Good general information I just learned related to firmaware flash:
Exporting the compiled file from the arduino IDE provides two hex files. One is a bootloader versiona and one is not. This was something I never considered because when we press the upload button and the arduino ide compiles and uploads, it takes care of it.
FYI: I was just about to ask which hex version to use, but I consulted my friend google.
apparently since we are uploading over serial, we use the bootloader hex version.
If we were programming over ISP, then the non bootloader hex can be used.
Here’s to hoping I don’t need to recalibrate… I guess I published my calibration numbers in a youtube video so in a pinch, there is that. Hope you all have a productive day.
