GPS on DM1701 best hardware hookup?
Posted: Thu Apr 20, 2023 4:31 pm
HI, Colin,
I'm working on a solution to add a GPS receiver to the DM1701. I found that the ATGM336H module for arduino sold on aliexpress for ~$4 fits easily in the DM1701.
Looking at the code , the GPS on/off function is compiled out of the firmware, so I'll have to generate a new image.
Do you know what would be the best GPIO pin to power the GPS module ? ( I can then add the turn on/off function back in the firmware)
I see that in non MDUV380 radios usart0 is used for the GPS data input. Do you know if this is available in the DM1701 or should I use another one ?
Thanks,
