Model A UART & Megalogger

Post by oakguy »

I had purchased the earlier Model A UART version 1.2 with the two connectors. Used it with the Uno and it worked well. I then went and purchased the ITEAD Mega board and Datalogger along with the 2.8 TFT Shield. I have never been able to get the UART to talk to the Megalogger. I have connected the UART to the TX and RX pins 1 & 2 on the datalogger. But it has always reported no OBD. I have updated the files from GitHub as well. I did change the Config.H to the UART setting. Any ideas?

Thanks

Make sure you make the necessary changes to config.h in megalogger.

Change this line:

Code: Select all

#define OBD_MODEL OBD_MODEL_I2C

To:

Code: Select all

#define OBD_MODEL OBD_MODEL_UART

Don't forget to connect GND.
