![]() ![]() I could go on more about it but lastly, I want to mention that the manual for the firmware is very thorough and that I’ve learned more about how GPIB works from that manual than from any other single source. ![]() ![]() Then there’s a small test utility so I didn’t have to work with terminal software. I think it can auto-configure for the Uno R3, Nano, Micro, Leonardo R3 and the Mega 2560 – handy for guys that need more pins for wireless operation or for extra sensors. It autodetected my Pro Micro and I didn’t need to change a single value from default, I just put the bits together (in minutes) and flashed it and it worked (just as soon as someone pointed out that I needed to set an address). While I’m at it I have to say I’m very impressed with the firmware that blog is all about, their version of AR488 just worked. That being the case, guys are making a separate interface for each instrument so no GPIB cables required at all – and that’s what I’m going to try next with Test Controller so my current issue will hopefully become a non-issue. It cost me $10 for 30 PCBs and $10 for 10 connectors so people can have a working GPIB interface for less than the cost of a used GPIB cable. Yes it seems a popular solution over on the “Topic: AR488 Arduino-based GPIB adapter” blog.
