I have a RS1D. I have it setup remotely with a solar panel. I want to monitor battery voltage using a MCP3008 ADC. The ADC communicates via the SPI interface. Does the RS use the SPI channels or does it only use UART on the RX TX pins?
I am hoping I can just connect the MISO, MOSI, SCLK and CS pins on the MCP3008 to the RP header and use it.
Thanks for your help.
