I did not know there is a internal E2PROM in lpcxpresso 1769 ,when I examine getting started document I saw internal E2PROM which is connected to P0.19 and P0.20 , so can I use it with I2C .I have never used I2C before so ı want to try this E2PROM.

Dear Zero ,I am waiting your answer , thank you man!

why did you write NO , I2C sample codes writed for this 24LC64. so there is a E2PROM...ofcourse , Its an options that solder it out ,it could be little weird for who never used it before .

#define Master_Buffer_BUFSIZE35
#define Slave_Buffer_BUFSIZE32

Could you explain , why buffer size allocated like that?
