2: iic question
is no problem to normal use iic control eeprom,but when i at front read/write iic take away eeprom, it will start err,ok no problem,but i connect the eeprom at err later(i also attempt software reset/clear flags etc), when i start iic again,the start err also occur. i measure the bus level found bus is low level, except reset i can't set the bus to high level again.
look forward to your reply.
