#162718 - Your code looks fine Responding to: ???'s previous message |
The common mistakes are not checking for an ACK when addressing a Slave.
And not doing the final NAK in a i2c_read() operation. You seem to have done both of these. Remember that a page write will wrap if you cross a page boundary. Just what exactly are you getting with your sequential read ? 0xFFs or just incorrect data ? David. |
