PixelRadio is a FM Radio Transmitter with RDS (Radio Data System) capabilities. It was developed for holiday "Pixel" displays (e.g., animated Christmas lights).
The GPIO Tab is used to configure the three programmable GPIO Pins.
These can be used for On/Off control of other devices via any of the four Controllers.
For example, use one of the GPIO pins to turn on a audio amplifier for your outdoor speakers when the light show begins.
The After boot, the GPIO pins are typically managed by the Serial, MQTT, or HTTP Controllers. The command keywords used to control the GPIO pins are summarized on the RDS Controllers page. For Local Control the GPIO Tab's boot state entries can be changed during runtime. The The The Any changes can be saved as default "Power-Up" settings.
