Using latest CO Gas sensor with Arduino-Programming help


hi there!

i'm building gas detection project detect co gas using arduino mega 2560 , ze03co. i'm having trouble understanding data sheet regards communication protocol , check sum calculations. can please explain me how , should use these calculations?

a checksum basic way try , ensure data integrity. random noise can cause bit errors on communication lines , make data appear way off.

if receive message , calculate checksum should match checksum @ end of message. if not match, data should thrown away.

the same checksum needs added message send well, give fucchecksum code help.
