Roving RN-42
|
|
||||||
============
|
|
||||||
|
|
||||||
Bug:
|
|
||||||
- with Nexus5 keyboard and mouse are very laggy.
|
|
||||||
|
|
||||||
- lose USB connection during power-down mode
|
|
||||||
- USB initialize code in main() causes this - WRONG
|
|
||||||
- Do not power-down during USB connection is active - DONE 11/11
|
|
||||||
(USB_DeviceState == USB_DEVICE_Configured) is used to check USB connection
|
|
||||||
matrix_power_down() matrix.c - 11/23
|
|
||||||
|
|
||||||
Todo:
|
|
||||||
|
|
||||||
Design:
|
|
||||||
- remove MCU dependent power saving code from core/keyboard
|
|
||||||
- it should be located in project matrix.c - DONE 11/23
|
|
||||||
- HHKB matrix.c needs matrix_prev?
|
|
||||||
- is_modified() is obsolete now. really needs?
|
|
||||||
|
|
||||||
|
|
||||||
LUFA:
|
|
||||||
USB connection check: state of USB deivce
|
|
||||||
- USB_DeviceState:
|
|
||||||
USB_Deivce_State_t { Unattached, Powered, Default, Addressed, Configured*, Suspended* }
|
|
||||||
- USB_IsInitialized: state of LUFA core setup
|
|
||||||
becomes true in USB_Init() USBController_AVR8.c
|
|
||||||
becomes false in USB_Disable() USBController_AVR8.c
|
|
||||||
- USB_VBUS_GetStatus(): state of VBUS(power/connection)
|
|
||||||
- USB_Disable() detaches, disables all interrupts, controller, PLL, regulater.
|
|
||||||
|
|
||||||
|
|
||||||
Power saving:
|
|
||||||
- confirm suspend mode lufa.c: matrix_power_*, suspend_wakeup_condition
|
|
||||||
- 8MHz clock
|
|
||||||
- When not connected in a few minutes get into deep sleep to save battery life
|
|
||||||
- CTS is needed for waking up from deep sleep? How deep sleep is activated?
|
|
||||||
- firmware controlled 3.3V DC converter to switch on/off BT module
|
|
||||||
- sleep MCU and BT module(keyboard is not used)
|
|
||||||
- deep sleep MCU and BT module(keyboard is not used for long time)
|
|
||||||
- deep sleep MCU and turn off BT module(keyboard is not used and not connected)
|
|
||||||
- Battery ADC; switching, high resistance
|
|
||||||
- switching gnd end of divider with PF4
|
|
||||||
- high resistor 100K/1M?
|
|
||||||
capacitor 10nF
|
|
||||||
http://www.eevblog.com/forum/beginners/measuring-battery-voltage-without-consuming-current/
|
|
||||||
- During USB suspend change clock source to internal RC from external Xtal(6.8)
|
|
||||||
- FRZCLK: you can freeze clock for power saving. still WAKEUPI and VBUSTI interrupts are available while freezing.(21.7.3)
|
|
||||||
- Suspend: Clear Suspend Bit, Freeze clock, disable PLL, MCU sleep(21.13)
|
|
||||||
|
|
||||||
Improving:
|
|
||||||
- BT LED; connecting, linked, sleeping, deep sleeping
|
|
||||||
- Battry LED; blink(using timer?)
|
|
||||||
- move rn42 to protocol directory when it becomes reusable stack
|
|
||||||
- LUFA sendchar should be buffered and serial_uart.c buffur size is too large(256).
|
|
||||||
- ADC resolution
|
|
||||||
AVR120
|
|
||||||
AVR32138
|
|
||||||
|
|
||||||
Testing:
|
|
||||||
- Factroy reset doesn't work; need to **test again** 10K pull-up is too high?
|
|
||||||
- Lipo voltage ADC value is not stabilized
|
|
||||||
- DCDC converter: squeaky inducter; try other inductors
|
|
||||||
|
|
||||||
- Keymap layer bug: during space is pressed(mousekey) press Fn(HHKB) then release space before Fn, in result HHKB layer is locked(toggled) unintentionally.
|
|
||||||
|
|
||||||
|
|
||||||
Done:
|
|
||||||
- low battery alert(solid light) 09/04

|
|
||||||
USB Power is boosted unnecessarily, not harmful?
|
|
||||||
|
|

Idea 1:
|

|

|
|

|
|
||||||
+--------------+ +------+ +------+ +-----+
|
|
||||||
To enable BT when USB powered it still needs to turn siwtch on, Lipo consumes quinscent current at 5V converter in vain.(Not good)
|
|
||||||
|
|
||||||
Idea 2:
|
|
||||||
(USB) +---(Lipo)
|
|
||||||
| | |

|
|
||||||
|Power Selector|-----+---|DC3.3V|-----|RN-42|
|
|
||||||
+--------------+ +------+ +-----+
|
|
||||||
MCU can controlled power of RN-42 without hardware switch.
|
|
||||||
When USB powered and switch is on Lipo consumes quinscent current at 5V converter in vain.(Not good)
|
|
||||||
|
|
||||||
Idea 3:
|

|
|
||||||
Switch is needed to save Lipo when not used because decent power saving is not available now. If firmware can turn off BT module completely and make MCU deep sleep the switch will be not even needed.

DONE:
|
|
||||||
- BT_INDICATOR LED turns on wrongly when touching line or pin. -- pull-up enabled on PF6/GPIO2 08/30
|
|
||||||
- Lipo charger configuration: fast charge time: USB charger spec? -- used 2kohm
|
|
||||||
- use LED of charger to alarm low battery. LED should be powered directly from Lipo? - cancel; powered from VUSB
|
|
||||||
- Use RTS in serial_uart.c to resolve missing chars from help message of RN-42 - done
|
|
||||||
- CTS/RTS lines are needed? just connect in loop back if no flow control is needed. - done
|
|
||||||
- add IO pin to charger status CHRG; LED control(low) and detect charge status(input HiZ) 07.24
|
|
||||||
- LINKED: add trace on PIO2 to PF6 07.24
|
|
||||||
- Lipo voltage ADC sensing
|
|
||||||
- Lipo charger MCP73831: needs capacitor 4.7uF *2
|
|
||||||
- USB connection check - 07.01
|
|
||||||
- BT on/off check: whether RX line is pulled up? - checking RTS 07.01
|
|
||||||
- USB/BT switching BT is on -> BT, BT is off -> USB - 07.01
|
|
||||||
- Under voltage lock out UVLO for protection of Lipo - Lipo has discharge protection at 3.100V 07.01
|
|
||||||
- Power saving: HHKB scan, BT radio control - 9h with 850mAh, this is enough 07.01
|
|
||||||
- Power selector doesn't work; Q4 MOSFET leaks from Lipo to USB power line. -- use Schottky instead 07/04

TROUBLE SHOOT
|
|
||||||
-------------
|
|
||||||
07/16 After fix of voltage dividor on GPIO6, had a trouble that it could not send a char to BT module, though could receive.
|
|
||||||
Found R8 had wrong 1K resistor and changed to 10K, after that it can send to the module again. Not sure how it had sent with the wrong 1K before.
|
|
||||||
|
|
||||||
07/18 On Linux, had an USB related trouble; keyobard or console didn't work for some reason. Changing PID cured this problem. Very annoying, took very long time before resolved it.

Pairing
|
|
||||||
-------
|
|
||||||
First, host initiates pairing process and once it is done, auto connect will work thereafter.
|
|
||||||
SM,3 Master mode
|
|
||||||
SM,4 Auto Connect DTR Mode uses GPIO6 to make and break connection(Mode =DTR)
|
|
||||||
confirm: auto connect works and control connection with GPIO6
|
|
||||||
SM,5 Auto Connect ANY Mode (Mode =ANY)
|
|
||||||
each time GPIO is set, make inquiry and connect to the first found device
|
|
||||||
SM,6 automatically reconnect(Mode =Pair)
|
|
||||||
confirm: auto connect works well but difficult to enter command mode.
|
|
||||||
|
|
||||||
SR,Z removes all remote addresses for reconnecting.
|
|
||||||
can be used to connect another host
|
|
||||||
SR,I registers last inquiry address
|
|
||||||
|
|
||||||
|
|
||||||
Fast data mode
|
|
||||||
--------------
|
|
||||||
The module enters fast data mode after 'remote configuration timer' window is passed from power on.
|
|
||||||
In this mode the module does not accept '$$$' to enter command mode.
|
|
||||||
|
|
||||||
Power Management
|
|
||||||
----------------
|
|
||||||
Inquiry and Page window Idle or Active (3.1.1)
|
|
||||||
Downside: delay in discovery or connection time
|
|
||||||
SI, // set inquiry scan window(discovery) on/off duty?
|
|
||||||
SJ, // set page scan window(connection)
|
|
||||||
This reduces averaege power >20mA to 5mA(3mA in Sniff mode)
|
|
||||||
|
|
||||||
Sniff mode Transmit
|
|
||||||
Sniff mode is disabled by default and radio is active continuously when connected.(25-30mA)
|
|
||||||
In Sniff mode the radio wakes up intermittently and sleeps in very low power mode.(2mA)
|
|
||||||
SW,<val> // set interval timer(*0.625ms) 0000-7FFF
|
|
||||||
|
|
||||||
Deep sleep Idle (3.1.2)
|
|
||||||
In this mode the module shuts down completly and only draws about 300uA. To enable this set the most signifant bit(0x8000) of Sniff interaval timer.
|
|
||||||
SW,8320 // deep sleep enable(interval=0x320*0.625=500ms)
|
|
||||||
In normal sleep the firmware is still running in idle mode, and wakes up about 20 times per second to check ports, update LEDs, etc. During deep sleep, the firmware actually stops runnig some tasks and the LEDs only update about once per second.
|
|
||||||
To wake from deep sleep there are three ways: (in worst case wake up takes 5ms)
|
|
||||||
*send a charactor to the UART(first charactor will be lost)
|
|
||||||
*toggle CTS low to high and wait 5ms
|
|
||||||
*wake automatically every slot time(<val>*0.625ms)
|
|
||||||
Once the radio is awake it stay active for exactly 1 second of inactivity and then sleeps again.
|
|
||||||
Downside: latency and data loss
|
|
||||||
|
|
||||||
Disable Output driver Idle or Active (3.1.3)
|
|
||||||
S%,1000 // set all GPIO pins(0-11) to inputs.
|
|
||||||
|
|
||||||
Lower Transmit Power Idle or Active (3.1.4)
|
|
||||||
SY,<hex> // transmit power setting(takes effect after a power cycle and reboot)
|
|
||||||
Downside: reducing effective range
|
|
||||||
|
|
||||||
|
|
||||||
Optimizig for Latency
|
|
||||||
---------------------
|
|
||||||
By default the firmware is optimized for throughput.
|
|
||||||
SQ,16 // set latency bit
|
|
||||||
SQ,0 // unset latency bit
|
|
||||||
|
|
||||||
|
|
||||||
Configuration timer settings
|
|
||||||
----------------------------
|
|
||||||
Remote configuration is used for the module to be configured with various commands over Bluetooth(SPP profile only?).
|
|
||||||
|
|
||||||
The module has remote configuration timer to allow remote configuration over Bluetooth after power up in Slave mode. In Master modes the remote configuration timer is set to 0(no remote configuration). (In Trigger Master mode the timer is used as an idle timer to break the connection after time expires with no charactors receive.)
|
|
||||||
ST,0 // no remote, no local when connected
|
|
||||||
ST,<1-252> // local and remote with timeout in seconds from power up
|
|
||||||
ST,253 // local only without timeout
|
|
||||||
ST,254 // remote only without timeout
|
|
||||||
ST,255 // local and remote without timeout
|
|

Memo of deveopment
|
||||||
|
==================
|
||||||
|
just memo, NOT WORTH READING
|
||||||
|
|
||||||
|
Bug:
|
||||||
|
- Factory Reset PIO4 doesn't work
|
||||||
|
- the reason is unclear - 12/08 NOT LOOK INTO ANY MORE
|
||||||
|
- WORKAROUND: use serial pins(3.3V, GND, RX and TX)
|
||||||
|
- SF,1 and R,1 to set factory defalult
|
||||||
|
|
||||||
|
|
||||||
|
Todo:
|
||||||
|
- LED cover and switch knob and new Slide Switch
|
||||||
|
- RN42 auto configuration
|
||||||
|
- configure the module as HID device every time powering up
|
||||||
|
- this'll reduce work load of assembly
|
||||||
|
|
||||||
|
- move rn42 to protocol directory when it becomes reusable stack
|
||||||
|
|
||||||
|
- sendchar() in lufa.c no buffer
|
||||||
|
- no buffering. character lost can be caused.
|
||||||
|
- LUFA sendchar should be buffered and serial_uart.c buffur size is too large(256).
|
||||||
|
|
||||||
|
- BT operations
|
||||||
|
- disconnect
|
||||||
|
- new connection

|
- remove connection

|
- sendchar() in lufa.c block loop - DONE 11/29
|
||||||
|
- block loop when powered with AC adapter
|
||||||

|
- remove argument from suspend_power_down() for backward compatitibility
|
||||||
|
- remove MCU dependent power saving code from core/keyboard - DONE 11/23
|
||||||
|
- it should be located in project matrix.c
|
||||||
|
- HHKB matrix.c needs matrix_prev?
|
||||||
|
- is_modified() is obsolete now. really needs?
|
||||||

- ADC: removing AREF capacitor C10
|

TROUBLE SHOOT
|
||||||
|
-------------
|
||||||
|
07/16 After fix of voltage dividor on GPIO6, had a trouble that it could not send a char to BT module, though could receive.
|
||||||
|
Found R8 had wrong 1K resistor and changed to 10K, after that it can send to the module again. Not sure how it had sent with the wrong 1K before.
|
||||||
|
|
||||||
|
07/18 On Linux, had an USB related trouble; keyobard or console didn't work for some reason. Changing PID cured this problem. Very annoying, took very long time before resolved it.
|
||||||
|
|
||||||
|
12/07 rn42_rts() read 1 every time. R12 broke in open mode(no coductive), idk why, too much heat with soldering? and PF1 pin was not soldered.
|
||||||
|
It resolved with resoldering PF1 and new resistor on R12.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Done:
|
||||||
|

|
||||||
|
* MCP73832 doesn't leak from Vcc pin when unpluged and battery powered
|
||||||
|
34mV vs 2.07V(MCP73831) at Vcc pin
|
||||||
|
MCP73832 doesn't need revese protection diode D5
|
||||||
|
* PMEG2010ER is very low VF while reverse current/voltage is high
|
||||||
|
VF=0.96 vs 1.98(RB160M-30TR)with Fluke 175
|
||||||
|
Anode of D11 is 680mV vs 20mV(RB160M-30TR)
|
||||||
|
780mV is still low < 1.4V VBUS plugin detection(21.11)
|
||||||
|
this doesn't cause false VBUS detect
|
||||||
|
and 780mV on MCP73832 Vcc pin is also no problem.
|
||||||
|
D5 can be removed.
|
||||||
|

||||||
|
- wrongly suspended when powered from adapter without USB connection - DONE
|

RN-42 Bluetooth Module Support
|
||||||
|
==============================
|
||||||
|
Bluetooth controller board works with HHKB Pro2, JP, Type-S and Type-S JP and it supports both USB and Bluetooth as keyboard output protocol. Bluetooth module Roving Networks/Microchip RN-42 is installed on the board.
|
||||||
|
|
||||||
|
|
||||||
|
Limitations:
|
||||||
|
- short battery life
|
||||||
|
- connection switching
|
||||||
|
the module always connects to the last linked device. Remote address setting does not work as expected.
|
||||||
|
- HHKB JP requires case modification for power switch and LEDs.
|
||||||
|
without switch power controlled by MCU? Probably using 3.3V regulator enable pin power of RN-42 can be controlled.
|
||||||
|
- Wiress certification of RN-42

||||||

Apple iOS
|
||||||
|
---------
|
||||||
|
Keyboard can be used with iPhone, but mouse cannot.
|
||||||
|
|
||||||
|
|
||||||
|
Android
|
||||||
|
-------
|
||||||
|
3.7.1.5 Note: To connect with Android phone the modules must wake up 11ms every 2.5seconds.
|
||||||
|
|
||||||
|
|
||||||
|
Power Management
|
||||||
|
----------------
|
||||||
|
Inquiry and Page window Idle or Active (3.1.1)
|
||||||
|
Downside: delay in discovery or connection time
|
||||||
|
SI, // set inquiry scan window(discovery) on/off duty?
|
||||||
|
SJ, // set page scan window(connection)
|
||||||
|
This reduces averaege power >20mA to 5mA(3mA in Sniff mode)
|
||||||
|
|
||||||
|
Sniff mode Transmit
|
||||||
|
Sniff mode is disabled by default and radio is active continuously when connected.(25-30mA)
|
||||||
|
In Sniff mode the radio wakes up intermittently and sleeps in very low power mode.(2mA)
|
||||||
|
SW,<val> // set interval timer(*0.625ms) 0000-7FFF
|
||||||
|
|
||||||
|
Deep sleep Idle (3.1.2)
|
||||||
|
In this mode the module shuts down completly and only draws about 300uA. To enable this set the most signifant bit(0x8000) of Sniff interaval timer.
|
||||||
|
SW,8320 // deep sleep enable(interval=0x320*0.625=500ms)
|
||||||
|
In normal sleep the firmware is still running in idle mode, and wakes up about 20 times per second to check ports, update LEDs, etc. During deep sleep, the firmware actually stops runnig some tasks and the LEDs only update about once per second.
|
||||||
|
To wake from deep sleep there are three ways: (in worst case wake up takes 5ms)
|
||||||
|
*send a charactor to the UART(first charactor will be lost)
|
||||||
|
*toggle CTS low to high and wait 5ms
|
||||||
|
*wake automatically every slot time(<val>*0.625ms)
|
||||||
|
Once the radio is awake it stay active for exactly 1 second of inactivity and then sleeps again.
|
||||||
|
Downside: latency and data loss
|
||||||
|
|
||||||
|
Disable Output driver Idle or Active (3.1.3)
|
||||||
|
S%,1000 // set all GPIO pins(0-11) to inputs.
|
||||||
|
|
||||||
|
Lower Transmit Power Idle or Active (3.1.4)
|
||||||
|
SY,<hex> // transmit power setting(takes effect after a power cycle and reboot)
|
||||||
|
Downside: reducing effective range
|
||||||
|
|
||||||
|
|
||||||
|
Optimizig for Latency
|
||||||
|
---------------------
|
||||||
|
By default the firmware is optimized for throughput.
|
||||||
|
SQ,16 // set latency bit
|
||||||
|
SQ,0 // unset latency bit
|
||||||
|
|
||||||
|
|
||||||
|
Configuration timer settings
|
||||||
|
----------------------------
|
||||||
|
Remote configuration is used for the module to be configured with various commands over Bluetooth(SPP profile only?).
|
||||||
|
|
||||||
|
The module has remote configuration timer to allow remote configuration over Bluetooth after power up in Slave mode. In Master modes the remote configuration timer is set to 0(no remote configuration). (In Trigger Master mode the timer is used as an idle timer to break the connection after time expires with no charactors receive.)
|
||||||
|
ST,0 // no remote, no local when connected
|
||||||
|
ST,<1-252> // local and remote with timeout in seconds from power up
|
||||||
|
ST,253 // local only without timeout
|
||||||
|
ST,254 // remote only without timeout
|
||||||
|
ST,255 // local and remote without timeout
