I have to generate check sum for Hex file that is having size approximately up to 52 K,I done the checksum generation settings in IAR EW STM8 as below:Fill pattern: 0xFF (can be any pattern)Start address: 0x0 (adjust to your application)End address: ...

I am trying to set the PORT E pins 1 and 2 (PE1 and PE2) as Output .When i am writing High on it, I am only getting 500mv and Low as 0v.There is no external push-pull circuitry involved.Let me know your comments.

I am able to send and receive Data by polling method but i am not able to receive.
