I was wondering how I could overcome the next issue;
My ESP8266 12E is connected as follows:
- GPIO0 ground if needed to program, vcc otherwise
- GPIO2 vcc
- GPIO15 ground
I also want to connect a MCP3002 to my ESP. However to use SPI I also need the GPIO15 pin to be connected to the Chip Select pin.
I tried connecting the GPIO15 pin from the ESP to the CS pin of MCP3002 and connecting ground in between. This did not work though, should I switch/remove the ground after boot somehow? (Or should I connect it differently?)
