I2C EEPROM Memory Read Problem [SOLVED]

Postby GeekCharge » Wed Jan 11, 2017 9:55 am

Hi,

I have an I2C eeprom connected to the pyboard v1.1 and I am having issues with reading the memory. Device comes up fine during scan, and I can read from it using mem_read method. However, it seems I can only read once, i.e. if I read let's say 10 bytes from start address 0 I will get some data that I know it's there, but if I execute any further reads from that point onward I only get 0xFF regardless of how much data I read. This will persist until I restart the whole setup. Any ideas?

Many thanks,
Geek

Solved! When reading the docs I was using old version prior to 16bit addressing being introduced. Now I can read the memory without issues.
