Blinky flashes the on-board LED.

Blinky flashes the on-board LED.

Crudeblinky flashes the on-board LED without using HAL.

Display draws on the connected display.

Dma shows how to use the DMA controller for RAM to RAM transfers.

Gpiotest tests all GPIOs exposed as the Pico 2 GPIO pins.

Irqpin shows how to setup an IO pin to be an interrupt source.

Readpin polls the state of the GP15 pin and shows it using the onboard LED.

Smpblinky tests the Go and noos schedulers.

SPI loop test: wire GP3 and GP4 together.

Uart allows to tests the communication over UART peripheral.

WS2812 uses the UART peripheral to drive the string of the WS2812 RGB LEDs.

Pico-8seg-led uses standard fmt.Fprintf function to prints different chars and numbers on the 8-segment display.

Pico-lcd-1.3 is similar to the Waveshare demo code for this module.

Pico-restouch-lcd-2.8 allows to test the LCD module.

Blinky flashes the both on-board LEDs using two goroutines.

Irqbtn shows how to use interrupts to wait for the onboard button to be pressed.

Smpblinky tests the Go and noos schedulers.

Package dma provides interface to the DMA controller.

Package dmairq allows to share the limited number of system-level DMA interrupts between the interrupt service routines (ISRs, interrupt hadlers) for individual DMA channels.

Package nocache allows to allocate variables and slices of arbitrary type in the DMA-capable non-cached memory.

Package init when imported configures the whole system for typical usage assuming it's RPI Pico 2 compatible, that is, it's clocked from 12 MHz crystal, the XIP QSPI Flash supports 133 MHz clock, the IOVDD >= 2.5 V. Both the CPU and Flash are configured to run at conservative 125 MHz.

Package riscvst provides the implementation of a tickless system timer based on the RISCV platform timer.
