Usage Notes You can use this CRC value to check data at a later date - to make sure it hasn't been changed, corrupted, deleted etc. They differ (at least) in the way which bit is shifted in first and also in the initialization of the flipflops. Data is possible to include via keyboard or from file. When this is used, anytime data in the 7 bytes changes, then the CRC must be recalculated, and sent out. In this example, the main program would have a transmit buffer (byte array) variable named serbuf[]. CRC operates anywhere in the world where our PPF methodology can be effective.
