#111480 - ur read function is not correct Responding to: ???'s previous message |
Hi narendar,
i think ur read function is not correct. it should be like this i2c_start(); i2c_send(0xa0);// device address with write i2c_send(0xXY);// word address nop(); i2c_start(); i2c_send(0xa1);// device address with read nop(); rcv_val = i2c_recv();// recving subroutine i2c_stop(); Also how u checked whether the eeprom is giving ack after writing.. |
