Hello. 1) As I understand format of i2c read command is following: 2, (dev_i2c_addr<<1)|1, addr_hi, addr_lo, size_hi, size_lo but in debug output I saw following commands: >>> 02 a3 00 01 <<< 55 >>> 02 a3 00 04 <<< 55 00 53 00 This commands are shorter then command described above. Meaning of bytes 1, 2 and 4 is clear, but what mean third byte: if it is size_hi, then where is address? if it is addr_lo, then it is not clear why answer's first byte is 55 according to Cypress documentation first byte of program eeprom should be C2 2) What is format for i2c write command? 3, dev_i2c_addr<<1, addr_hi, addr_lo, data... ? 3) what mean following command >>> 03 a2 51 3f 80 write byte 80 at address 513f?
