#100217 - Software driven UART - Bit-banging
Responding to: Dan Henry's previous message
Look at the receiver output with a scope and see how much noise is present and whether you expect a UART to clock in the data properly. You see, it takes only something with the appearance of a start bit to get the UART started shifting in bits.


I will test it with my software oscilloscope

I have been informed that if I use bit-banging at the receiver instead of UART, would solve the problem. I don't know it is true or not.

And most likely bit-banging at the transmitter too. Bit-banging transmit and receive are done when internal peripheral subsystems in incapable of generating the waveform of the encoding scheme chosen to suit the RF link's characteristics.



Do you have bit-banging for transmitter and receiver in C language for 8051?

I really need it asap
