I've been having no luck getting I2C to work with my FRDM-KE02Z board.. I'm using the KDS 1.0.1 IDE and attempting to use the built-in component library, but I am obviously doing something wrong. I've enabled the devices and chose the appropriate slave, but every time I try to read/write data, I get an error (ERR_DISABLED)... It would seem that maybe I'm not correctly enabling turning the I2C hardware. a code snippet is below, "Accelerometer" is an "InternalI2C" component.
Accelerometer_Init();
error = Accelerometer_Enable(); // enable the accelerometer
printf("Err:%3d \r\n", error);
error = Accelerometer_SelectSlave(0x1D); // accelerometer address is 0x1D
printf("Err:%3d \r\n", error);
error = Accelerometer_SendChar(0x40); // reset the accelerometer
printf("Err:%3d \r\n", error);
// while( 1 )
// {
error = Accelerometer_SendChar(0x00); // Send start address
printf("Err:%3d \r\n", error);
error = Accelerometer_RecvBlock(AData, 7, &bytes); // read back 7 bytes
printf("Err:%3d \r\n", error);
error = Accelerometer_RecvChar(&bytes);
printf("Err:%3d \r\n", error);
status = AData[0];
// xG = (AData[1]<<8) + AData[2];
// yG = (AData[3]<<8) + AData[4];
// zG = (AData[5]<<8) + AData[6];
xG = AData[1];
yG = AData[3];
zG = AData[5];
printf("Err:%3d BytesRX:%3d Status:%3d X:%6d Y:%6d Z:%6d\r\n", error, bytes, status, xG, yG, zG);
