- uprintf -> dprintf - Fix atsam "vendor" eeprom. - Bump Kinetis K20x to 64 bytes, too. - Rollback Kinetis to 32 bytes as partitioning can only be done once. Add warning about changing the value. - Change RAM-backed "fake" EEPROM implementations to match eeconfig's current usage. - Add 24LC128 by request.pull/7993/head

# EEPROM Driver Configuration | |||||
The EEPROM driver can be swapped out depending on the needs of the keyboard, or whether extra hardware is present. | |||||
Driver | Description | |||||
--------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | |||||
`EEPROM_DRIVER = vendor` | Uses the on-chip driver provided by the chip manufacturer. For AVR, this is provided by avr-libc. This is supported on ARM for a subset of chips -- STM32F3xx, STM32F1xx, and STM32F072xB will be emulated by writing to flash. Other chips will generally act as "transient" below. | |||||
`EEPROM_DRIVER = i2c` | Supports writing to I2C-based 24xx EEPROM chips. See the driver section below. | |||||
`EEPROM_DRIVER = transient` | Fake EEPROM driver -- supports reading/writing to RAM, and will be discarded when power is lost. | |||||
## Vendor Driver Configuration | |||||
No configurable options are available. | |||||
## I2C Driver Configuration | |||||
Currently QMK supports 24xx-series chips over I2C. As such, requires a working i2c_master driver configuration. You can override the driver configuration via your config.h: | |||||
`config.h` override | Description | Default Value | |||||
------------------------------------------- | ----------------------------------------------------------------------------------- | ------------------------------------ | |||||
`#define EXTERNAL_EEPROM_I2C_BASE_ADDRESS` | Base I2C address for the EEPROM -- shifted left by 1 as per i2c_master requirements | 0b10100000 | |||||
`#define EXTERNAL_EEPROM_I2C_ADDRESS(addr)` | Calculated I2C address for the EEPROM | `(EXTERNAL_EEPROM_I2C_BASE_ADDRESS)` | |||||
`#define EXTERNAL_EEPROM_BYTE_COUNT` | Total size of the EEPROM in bytes | 8192 | |||||
`#define EXTERNAL_EEPROM_PAGE_SIZE` | Page size of the EEPROM in bytes, as specified in the datasheet | 32 | |||||
`#define EXTERNAL_EEPROM_ADDRESS_SIZE` | The number of bytes to transmit for the memory location within the EEPROM | 2 | |||||
`#define EXTERNAL_EEPROM_WRITE_TIME` | Write cycle time of the EEPROM, as specified in the datasheet | 5 | |||||
Default values and extended descriptions can be found in `drivers/eeprom/eeprom_i2c.h`. | |||||
Alternatively, there are pre-defined hardware configurations for available chips/modules: | |||||
Module | Equivalent `#define` | Source | |||||
-----------------|---------------------------------|------------------------------------------ | |||||
CAT24C512 EEPROM | `#define EEPROM_I2C_CAT24C512` | <https://www.sparkfun.com/products/14764> | |||||
RM24C512C EEPROM | `#define EEPROM_I2C_RM24C512C` | <https://www.sparkfun.com/products/14764> | |||||
24LC128 EEPROM | `#define EEPROM_I2C_24LC128` | <https://www.microchip.com/wwwproducts/en/24LC128> | |||||
24LC256 EEPROM | `#define EEPROM_I2C_24LC256` | <https://www.sparkfun.com/products/525> | |||||
MB85RC256V FRAM | `#define EEPROM_I2C_MB85RC256V` | <https://www.adafruit.com/product/1895> | |||||
?> If you find that the EEPROM is not cooperating, ensure you've correctly shifted up your EEPROM address by 1. For example, the datasheet might state the address as `0b01010000` -- the correct value of `EXTERNAL_EEPROM_I2C_BASE_ADDRESS` needs to be `0b10100000`. | |||||
## Transient Driver configuration | |||||
The only configurable item for the transient EEPROM driver is its size: | |||||
`config.h` override | Description | Default Value | |||||
------------------------------- | ----------------------------------------- | ------------- | |||||
`#define TRANSIENT_EEPROM_SIZE` | Total size of the EEPROM storage in bytes | 64 | |||||
Default values and extended descriptions can be found in `drivers/eeprom/eeprom_transient.h`. |
