-### Configuration :id=avr-configuration
+You'll need to determine which pins can be used for I2C -- a an example, STM32 parts generally have multiple I2C peripherals, labeled I2C1, I2C2, I2C3 etc.
 
-The following defines can be used to configure the I2C master driver.
+To enable I2C, modify your board's `halconf.h` to enable I2C:
-
-|Variable          |Description                                        |Default|
-|------------------|---------------------------------------------------|-------|
-|`F_SCL`           |Clock frequency in Hz                              |400KHz |
-
-AVRs usually have set GPIO which turn into I2C pins, therefore no further configuration is required.
-
-## ARM :id=arm
-
-For ARM the Chibios I2C HAL driver is under the hood.
-This section assumes an STM32 MCU.
-
-### Configuration :id=arm-configuration
-
-The configuration for ARM MCUs can be quite complex as often there are multiple I2C drivers which can be assigned to a variety of ports.
-
-Firstly the `mcuconf.h` file must be setup to enable the necessary hardware drivers.
-
-|Variable                      |Description                                                                        |Default|
-|------------------------------|------------------------------------------------------------------------------------|-------|
-|`#STM32_I2C_USE_XXX`          |Enable/Disable the hardware driver XXX (each driver should be explicitly listed)    |FALSE  |
-|`#STM32_I2C_BUSY_TIMEOUT`     |Time in ms until the I2C command is aborted if no response is received              |50     |
-|`#STM32_I2C_XXX_IRQ_PRIORITY` |Interrupt priority for hardware driver XXX (THIS IS AN EXPERT SETTING)              |10     |
-|`#STM32_I2C_USE_DMA`          |Enable/Disable the ability of the MCU to offload the data transfer to the DMA unit  |TRUE   |
-|`#STM32_I2C_XXX_DMA_PRIORITY` |Priority of DMA unit for hardware driver XXX (THIS IS AN EXPERT SETTING)            |1      |
-
-Secondly, in the `halconf.h` file, `#define HAL_USE_I2C` must be set to `TRUE`. This allows ChibiOS to load its I2C driver.
-
-Lastly, we need to assign the correct GPIO pins depending on the I2C hardware driver we want to use.
-
-By default the I2C1 hardware driver is assumed to be used. If another hardware driver is used,  `#define I2C_DRIVER I2CDX` should be added to the `config.h` file with X being the number of hardware driver used. For example is I2C3 is enabled, the `config.h` file should contain `#define I2C_DRIVER I2CD3`. This aligns the QMK I2C driver with the Chibios I2C driver.
-
-STM32 MCUs allows a variety of pins to be configured as I2C pins depending on the hardware driver used. By default B6 and B7 are set to I2C. You can use these defines to set your i2c pins:
-

-| `I2C1_SCL`               | The pin number for the SCL pin (0-15)                                                        | `6`     |
-| `I2C1_SDA`               | The pin number for the SDA pin (0-15)                                                        | `7`     |
-| `I2C1_BANK` (deprecated) | The bank of pins (`GPIOA`, `GPIOB`, `GPIOC`), superceded by `I2C1_SCL_BANK`, `I2C1_SDA_BANK` | `GPIOB` |

-The ChibiOS I2C driver configuration depends on STM32 MCU:
-
-    STM32F1xx, STM32F2xx, STM32F4xx, STM32L0xx and STM32L1xx use I2Cv1;
-    STM32F0xx, STM32F3xx, STM32F7xx and STM32L4xx use I2Cv2;
-
-#### I2Cv1 :id=i2cv1
-STM32 MCUs allow for different clock and duty parameters when configuring I2Cv1. These can be modified using the following parameters, using <https://www.playembedded.org/blog/stm32-i2c-chibios/#I2Cv1_configuration_structure> as a reference:
-
-| Variable           | Default          |

-| `I2C1_CLOCK_SPEED` | `100000`         |
-| `I2C1_DUTY_CYCLE`  | `STD_DUTY_CYCLE` |
-
-#### I2Cv2 :id=i2cv2
-STM32 MCUs allow for different timing parameters when configuring I2Cv2. These can be modified using the following parameters, using <https://www.st.com/en/embedded-software/stsw-stm32126.html> as a reference:
-
-| Variable              | Default |

-| `I2C1_TIMINGR_SCLH`   | `15U`   |
-| `I2C1_TIMINGR_SCLL`   | `21U`   |
-
-STM32 MCUs allow for different "alternate function" modes when configuring GPIO pins. These are required to switch the pins used to I2Cv2 mode. See the respective datasheet for the appropriate values for your MCU.
-
-| Variable            | Default |
-|---------------------|---------|
-| `I2C1_SCL_PAL_MODE` | `4`     |
-| `I2C1_SDA_PAL_MODE` | `4`     |
-
-#### Other :id=other
-You can also overload the `void i2c_init(void)` function, which has a weak attribute. If you do this the configuration variables above will not be used. Please consult the datasheet of your MCU for the available GPIO configurations. The following is an example initialization function:
 
 ```c
-void i2c_init(void)
+#define HAL_USE_I2C TRUE
-{
+```
-  setPinInput(B6); // Try releasing special pins for a short time
-  setPinInput(B7);
-  wait_ms(10); // Wait for the release to happen
 
-  palSetPadMode(GPIOB, 6, PAL_MODE_ALTERNATE(4) | PAL_STM32_OTYPE_OPENDRAIN | PAL_STM32_PUPDR_PULLUP); // Set B6 to I2C function
+Then, modify your board's `mcuconf.h` to enable the peripheral you've chosen, for example:
-  palSetPadMode(GPIOB, 7, PAL_MODE_ALTERNATE(4) | PAL_STM32_OTYPE_OPENDRAIN | PAL_STM32_PUPDR_PULLUP); // Set B7 to I2C function
+
+```c

 You'll need to determine which pins can be used for SPI -- as an example, STM32 parts generally have multiple SPI peripherals, labeled SPI1, SPI2, SPI3 etc.
 
-To enable SPI, modify your board's `halconf.h` to enable SPI - both `HAL_USE_SPI` and `SPI_USE_WAIT` should be `TRUE`, and `SPI_SELECT_MODE` should be `SPI_SELECT_MODE_PAD`.

-Then, modify your board's `mcuconf.h` to enable the SPI peripheral you've chosen -- in the case of using SPI2, modify `STM32_SPI_USE_SPI2` to be `TRUE`.
 
-As per the AVR configuration, you may select any other standard GPIO as a slave select pin, and can be supplied to `spi_start()`.
+```c
+#define HAL_USE_SPI TRUE

 Configuration-wise, you'll need to set up the peripheral as per your MCU's datasheet -- the defaults match the pins for a Proton-C, i.e. STM32F303.
