 		 #100343 - why analyze how deep the water is before
Responding to: ???'s previous message
You need to answer that question before you jump in and start writing code...
Why analyze how deep the water is before you jump in, all that can happen is that you hurt your head and maybe break your neck.
Many can write code - great, but few take the time to find out what code to write.
For instance in theis thread there is a question "why not use the HW UART" and where is the answer?

"I tried to implement serial communication using with hardware UART in order to transmit simple byte to another microcontroller ... and learnt that the blue or red LED would not switch on. ... I prefer to test it with bit-banging (software UART) in order to see if it work better."

The "problems" do not have one minuscule iota of relation to whether soft or hard UART is used.
Si, instead of fixing the actual problem, the OP start bungling around wasting time with a soft UART only to find - who knows how much later - that the problem was not the UART.

LET IT BE CLEAR: using a soft UART when the hardware UART is availible is a total waste of time and resources
