Programming Nano DCCduino

Post by goudard »

Hello Freematics,
I just received your kit Nano+Screen+OBD2 cable, great !
I installed the libraries in Arduino software environement.
And then I tried to load the NanoLogger program into the board.
Unfortunately I get the following error:

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x41

I tried many workaround to solve this but no one worked. I am using mac os x Mojave.
Can you help me to solve that tricky issue?
If you need further detail please do not hesitate to ask.
Thanks you in advance,
Regards,
Olivier

This error means the IDE cannot communicate with the board.
I set these configs, which worked for my Mac High Sierra install:

Board = Arduino Nano
Processor = ATmega328P (Old Bootloader)
Port = /dev/cu.usbserial-1410

Also, I found I had to disconnect the OBD adapter and the screen before programming would work, as there is only one serial interface on the Nano.

If you don't see /dev/cu.Xxx as port selection, you may need to install 3rd party Serial USB driver.

NOTE: The drivers were already installed on my High Sierra install so I have no tested the above serial drivers. Use at your own risk.
