Dear all,

Why am i keep getting this error by using return function in my coding?

can anyone explain and help me further on this CRC checksum coding ?

Your early reply is much appreciated.

Thank you.

Hi Joonsin,

you cannot return a value in a function which has a return type of 'void'.

So instead

void crc16(void) {

you have to write

int crc16(void) {

And the AS1_SencChar() after the return does not make any sense.

All these are basic C programming points.

I hope this helps,

Erich
