I recently got a CAN485-Dev Board and tried connecting it to Arduino IDE through my computer. I installed the library and made sure the IDE could recognize the board. But, whenever I try to upload any code, I keep getting this error: "“avrdude: ser_open(): can’t open device “\.\COM8”: Access to the port ‘COM8’ is denied”. Does anyone know how to resolve this issue?
Try swapping physical ports, restarting the machine, run the program “as admin”…any luck?
Also ensure that you have the board pkg https://learn.sparkfun.com/tutorials/as … stallation
Hey! Thanks for your suggestions! I tried all of those, and consulted the guide posted too. But the board is still giving me the same problem. Is there anything else I can do?
