The I2C Device address problem of MQX 4.1.1

Hello everyone,

    

          When I got starting with MQX 4.1.1 and tested the E2PROM program,I found the problem which the device address of E2PROM (24LC04) was '0x50',it should be '0xA0' or others.

          the above is the problem with the I2C example, <install_dir>\Freescale\Freescale_MQX_4_1\mqx\examples\i2c

 

          so, I rectify the address to '0xA0' (AT24C02) for my test E2PROM,I find the start ACK signal is '1' going wrong.

 

          Can anyone offer me a I2C operation (poll or interrupt based on MQX 4.1.1) example?

 

          THks!

 

Best Regards!
