writing and reading from I2c eeprom ?

[RixtronixLAB]

Dear Members,

Where can I find from software development kit the example for writing and reading from I2C EEPROM ?

Thanks

I got :

[1;37m[1;32muart_cli:~$ [1;37meeprom clear
                                 
[1;31mcommunication error
                                                    
[1;37m[1;32muart_cli:~$ [1;37meeprom clear
                                 
[1;31mcommunication error
                                                    
[1;37m[1;32muart_cli:~$ [1;37m                                               
                                         

what do I miss ? I use a real 24C16 chip

Is that what you're actually seeing on your terminal?

You need to remove the escape sequences to make that legible.

you should start with the TWI Scanner to verify your hardware connections, and Slave Address

on TWI scanner, I can not find 0xA0, which is 24C16, what do I miss ?

nfo> app: TWI scanner started.
                                               

nfo> app: TWI device detected at address 0x3C.
