Hardware

I have the Raspberry PI 3A+ working with Python 3 when I use USB to USB. I can use ardSerial.py to send commands. So I know I have the software setup correctly on the Raspberry PI and that the Nyboard responds.

I have soldered the 2 x 5 socket on and when I connect this way, the commands do not work. It seems to upload them, but never comes back from the operation.

minicom connection is similar - no errors - but no response upon connecting.

The Raspberry PI fires up and I can access it when connected this way - so at least the power is working.

Suspecting a possible bad solder job, I have remelted the solder joints to reset them - did not help. I have 1 wire disabled, serial port enabled per the instructions (but I think if I had this wrong it would show up in the USB to USB test?) I bent the 6 pin programming connector 180 degrees to connect both the computer and the Raspberry PI to troubleshoot. When I send commands from the Pi, the serial monitor on the usb port is not seeing anything and it just hangs forever. Things I'm wondering about: Question 1: I have reloaded Bittle's WriteInstinct in the past - is it possible that there is a missing library (even if it works via USB - seems unlikely).

Question 2: Is there any way to diagnose a bad pin from either side? Question 3: Putting a new 2 x 5 on the board would be challenging for my desoldering skills - would anyone here suspect the connector block itself? Question 4: I am using the /dev/ttyAMA0 port - but that port is present even when the Pi is not connected to the Nyboard. Does that sound right or indicate a hardware problem? FYI I have all my code in a Git repo that I will make public. With a single curl command you will be able to download and configure all that I've done. Once it's working I will share!
