[differential_manchester](pio/differential_manchester)| Send and receive differential Manchester-encoded serial (BMC).
[hub75](pio/hub75)| Display an image on a 128x64 HUB75 RGB LED matrix.
[i2c](pio/i2c)| Scan an I2C bus.
[ir_nec](pio/ir_nec)| Sending and receiving IR (infra-red) codes using the PIO.
[logic_analyser](pio/logic_analyser)| Use PIO and DMA to capture a logic trace of some GPIOs, whilst a PWM unit is driving them.
[manchester_encoding](pio/manchester_encoding)| Send and receive Manchester-encoded serial.
[pio_blink](pio/pio_blink)| Set up some PIO state machines to blink LEDs at different frequencies, according to delay counts pushed into their FIFOs.

[spi](pio/spi)| Use PIO to erase, program and read an external SPI flash chip. A second example runs a loopback test with all four CPHA/CPOL combinations.
[squarewave](pio/squarewave)| Drive a fast square wave onto a GPIO. This example accesses low-level PIO registers directly, instead of using the SDK functions.
[st7789_lcd](pio/st7789_lcd)| Set up PIO for 62.5 Mbps serial output, and use this to display a spinning image on a ST7789 serial LCD.
[quadrature_encoder](pio/quadrature_encoder)| A quadrature encoder using PIO to maintain counts independent of the CPU.
[uart_rx](pio/uart_rx)| Implement the receive component of a UART serial port. Attach it to the spare Arm UART to see it receive characters.
[uart_tx](pio/uart_tx)| Implement the transmit component of a UART serial port, and print hello world.
[ws2812](pio/ws2812)| Examples of driving WS2812 addressable RGB LEDs.
