CRC - Build Signature and Rebuild to test.

The CRC is first used to build a signature using a seed and multiple data values. This signature is considered as the checksum and can be sent by a UART connection along with the data to verify the correct data has been sent. The second half of this program is used to test the CRC checksum of the data that has been created, by recreating the same checksum and comparing it to the first checksum. If the two checksum are equal, then P1.0 is set and the LED is turned on. Breakpoints can be set before the CRC_setData() function to observe the CRC register values and see the subsequent signatures before/after each data set.

Tested On: MSP430FR5969

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

• CRC peripheral
• GPIO Port peripheral

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.

• NONE
