EEPROM support for FT24C256A BBT SKR 1.4

[K2AAE]

The SKR 1.4 EEPROM Module has a FT24C256A device, looks to be pin compatible with 24LC16B/24AAxxx devices allowing a device swamp to be compatible with the existing drivers, it appears. Has anyone tried to swamp out the part?

Has anyone tried to swamp out the part?

It should not be neccesary to do that, try with setting EEPROM_ENABLE to 2 for 64 byte pagesize in my_machine.h first:

grblHAL/drivers/LPC1769/src/my_machine.h

Line 39 in 9f405ba

//#define EEPROM_ENABLE 1 // I2C EEPROM support. Set to 1 for 24LC16(2K), 2 (64 byte pages) or 3 (32 byte pages) for larger sizes. Requires eeprom plugin.

You have to change the board map as well as it does not allow EEPROM, looks like replacing this code

grblHAL/drivers/LPC1769/src/btt_skr_1.4_turbo_map.h

Lines 33 to 35 in 9f405ba

	#if EEPROM_ENABLE
	#error "This board cannot be used with current EEPROM code!"
	#endif

with

#define I2C_ENABLE 2

should work.
