I hope someone can help this analog design guy from the past. I have had a Banggood 328 tester for about a couple of years now, been working fine and use it daily. Last week the display wouldn't show any characters, power LED would come on, if I inserted a LED in the test zip it would flash a few times, checked the power supply, ok. 2.5V reference, ok. So I borrowed a friends same tester and swapped the 328 from his to mine, (thank God for sockets) and it works, so my 328 is bad. I just ordered a couple of new 328's (one for a spare) to replace mine in case it's not just a software problem. This is where I am at this point, I have no knowledge on programming accept some very basic Arduino stuff, I have only a MAC, all the threads on programing the 328 that I have read on this thread are way over my head, it's all Greek to me. Is there someone on here that could program a couple of 328 for me or another idea. Thanks in advance.
