Test code

Testing peripherals on the custom RP2350B servo controller PCB.

Commands

Warning

The zephyr sdk has bug in the rp2350 pinctrl file. The RP2_PINCTRL_GPIO_FUNC_UART_AUX macro is defind, but RP2_PINCTRL_GPIO_FUNC_UART_ALT macro is used. A pull request has been made to fix this.

Note

While shell is over USB, the adc scan_for command uses uart. The UART uses spi1 pins, so the spi1 needs to be disabled and extra_uart.overlay needs to be used.

Command	Parameters	Description
`led set <id> <on\|off>`	`id`: `0-1`	Set LED state
`led allon`	-	Turn all LEDs ON
`led alloff`	-	Turn all LEDs OFF
`servo set <id> <angle>`	Servo ID, angle in degrees	Set servo angle
`adc read <id>`	ADC channel ID	Read a single ADC channel
`adc read_for <id> <count>`	ADC channel ID, sample count	Read one ADC channel repeatedly
`adc scan`	-	Read all ADC channels once
`adc scan_for <count>`	`count ≤ 1024`	Read all ADC channels repeatedly and log timestamps
