I've had an OSEPP nano (arduino compatible) for a while now, and have begun working out its programming and setup.
I have finally worked out its sync and connection issues (apparently having an external power connected to Vin causes the unsync- power needs to come from usb to get upload to work), and successfully uploaded my first sketch to it (blink LED on digital pin 5).
... and weirdness happens. Sketch "pinMode (5, OUTPUT)" with "DigitalWrite (5, HIGH)".. etc, causes not digital pin 5 to blink.. but rather digital 1 pin!!
When I change the sketch to pin1, no pins perform the flash.
So it seems the sketch pin assignments, and the pin arrangements of the chip itself, do not match.
I have searched for OSEPP specific nano drivers or whatever, and no such thing exists. (Arduino nano w/ATmega 328 is the board it works with).
so... what do you guys think the issue is? OSEPP not actually being compatible? firmware/bootloader glitch New arduino program changes? Faulty controller?
how could I fix this or figure it out?
