Hi, thanks for ur reply.
May i know should i add in any decoder and encoder chip in my block diagram design for the decoding and encoding purpose?
Or this can be done juz in programming? So, that mean i dun need any hardware for the encoding and decoding part?
1 more things, i read from somewhere said that the data will be inverted after the rs232 conversion.
so if it is true, so the data that we transmit out will be in the inverted form and the receiving part juz simply receive the data without any further action in my design.
so, is it still valid?
Thanks.
