#143491 - two uC are able to read .. Responding to: ???'s previous message |
Does the System work if the second CPU is in, but not talking?
-- yes, both controllers were able to read from 24c02 .but not able to write . -- with only one controller on board(i.e. when other uC is removed from board) there is no problem in read and write operations. |
