The `PIO` subsystem is a Raspberry Pi RP2040 specific implementation, using the integrated PIO peripheral and is therefore only available on this MCU. Because of the flexible nature of the PIO peripherals, **any** GPIO pin can be used as a `TX` or `RX` pin. Half-duplex and Full-duplex operation is fully supported. The Half-duplex operation mode uses the built-in pull-ups and GPIO manipulation on the RP2040 to drive the line high by default. An external pull-up is therefore not necessary. -Configure the hardware via your config.h: +You may optionally switch the PIO peripheral used with the following define in config.h: ```c #define SERIAL_PIO_USE_PIO1 // Force the usage of PIO1 peripheral, by default the Serial implementation uses the PIO0 peripheral ``` diff --git a/docs/ws2812_driver.md b/docs/ws2812_driver.md index f8cad20ce0..9b79cfa905 100644 --- a/docs/ws2812_driver.md +++ b/docs/ws2812_driver.md @@ -170,7 +170,7 @@ To configure it, add this to your rules.mk: WS2812_DRIVER = vendor ``` -Configure the hardware via your config.h: +You may optionally switch the PIO peripheral used with the following define in config.h: ```c #define WS2812_PIO_USE_PIO1 // Force the usage of PIO1 peripheral, by default the WS2812 implementation uses the PIO0 peripheral ``` |
