Re: Part IV: Fundamentals of Digital Debugging

NO RATINGS
Jon, on using this small receipt printers as a debugger: what about the time overhead implied it the communication with the I/O interface?

 

A:  After you connect the printer, you just push one or two bytes into the UART and proceed with the main program.  The overhead is small.  And during the type of debugging for which I use the small printer, I'm not concerned too much about a few extra instructions or real-time performance.
