Only related topic I found from 2011
I have a very similar application to the above thread. I have a piece of industrial equipment that displays an output to a 16x2 display. I would like to be able to read the text data so that I could do better logging and monitoring based on the messages it displays. I do know mine is also in 8 bit mode. I was wondering if anyone had figured out how to do this after 9 years.
My plan to approach this if there aren't any better suggestions will be to use their code at a higher multiple frequency to sample a string of data. Then parse it out to find where it repeats and from there separate it out into the 8 bit strings. If I can then convert the bits into the text I expect, I can then figure out how to "sync" the two devices using the rising or falling edge with probably some offset. That seems to be where the previous effort fell short.
