Version 3 has been released!

{DR?} command (Request Digital Read)

Request the binary (0/1) value of a pin (GPIO)


{DR?} pin

  • pin - the GPIO (or pin name) of the pin to be read
The value of the pin will be returned by a {DR} command. The pin in the return command will be the same as supplied on the {DR?} command. i.e. if you send a GPIO number you will get that number back. If you send a valid pin name you will get that back.

For example if you send:
{DR?} D5
the reply will be something like:
{DR}D5 ␑ 0

Note the ESP8266/Wemos D1 supports the following pins:
  • GPIO 0 (D3)
  • GPIO 1 (D10/TX)
  • GPIO 2 (D4)
  • GPIO 3 (D9/RX)
  • GPIO 4 (D2/SDA)
  • GPIO 5 (D1/SDL)
  • GPIO 12 (D6)
  • GPIO 13 (D7)
  • GPIO 14 (D5)
  • GPIO 15 (D8)
  • GPIO 16 (D0)
