Does the I2C function in processor expert automatically generate and send the CRC packet?

Hi,

I'm using the KL43z SDK processor expert function:

It sends the command, command length, data and data length; but the crystalfontz display I'm using requires a CRC for every interaction. Does the function do this automatically? If not, how do I send the CRC packet?

Thanks!

Chris

Hi, Christopher,

As you know that IIC module transfer data based on timing, it does not transfer packet, I do not think there is any CRC concept, maybe this is the display issue.

Hope it can help you.
