FREMO Fast Clock

This is a fast clock implementation based on a 2.4GHz wireless transmission layer based on NRF24 controllers. The software runs in two modes: Master or Client. A GPIO pin decides which role the hardware should play.

The definitions in config.h define the ports to be used:

  • PIN_MASTER_CLIENT_SELECT defines the pin to be used to identifiy master or client. If that pin is LOW, then master is identified.
  • PIN_NRF24_CE defines the pin that is used for the CE signal
  • PIN_NRF24_CSN defines the pin that is used for the CSN signal
  • PIN_RELAY1 defines the pin that controls relay 1
  • PIN_RELAY2 defines the pin that controls relay 2
  • DEFAULT_HOLD_RELAY_MS 150
  • DEFAULT_MIN_RELAY_OFF_TIME_MS 80
  • DEFAULT_RELAY_ACTIVE_LOW true

Depending of the controller used, an SD1306 controlled display can be used. See the "-D WITH_DISPLAY" flag in the build_flags definition of the appropriate environment.
