# Problem To better understand how a CRC helps detect errors, edit the scrolling message to alter one or more of the characters. What happens to the CRC values? What happens to the red LED array? # Process The CRC value stored in the `CRC_Tx` variable was calculated for the message originally provided in the `Message[]` variable declared at the top of `main.c`. If the contents of `Message[]` are changed, the CRC value that's calculated from it will be different than what is stored in `CRC_Rx`. Since the values are now different, the red LEDs will light up to show the difference between the two values. # Answer The CRC values will be different. The red LEDs will light up to show the difference between the two values.
