* usb: unify handling of length parameters The length parameters in USB packets are strict and the existing implementation does already hardcode the length within the serialize functions. Therefore the user should not provide these lengths during creation time. In order to make this more verbose use defaults values within the structs and reference these defaults values within the serialization functions. It's not possible to remove these fields completly as this fields are used within deserialization from the hardware itself. Signed-off-by: Tobias Kohlbau <tobias@kohlbau.de> * Remove length fields as they are obsolete. The lengths is only required during the serialization and therefore is already hardcoded. The only other convinience is the calculation of the descriptor size, but this is already wrong. extern structs are padded and therefore do not have the right sizes.

Examples for the BSP raspberrypi-rp2040
Demos
All demos that run on the RaspberryPi Pico can also be run on the RP2040-Plus without modification.
- adc on RaspberryPi Pico
This example takes periodic samples of the temperature sensor and prints it to the UART using the stdlib logging facility. - blinky on RaspberryPi Pico
Blinks the LED on the board. - blinky core1 on RaspberryPi Pico
Blinks the LED on the board using the second CPU. - flash program on RaspberryPi Pico
Writes and reads data into the flash. - gpio clk on RaspberryPi Pico
Enables aCLKOUTmode on GPIO0. - i2c bus scan on RaspberryPi Pico
Prints all I²C devices on UART0 (Pin 0,1) attached to I²C on SCL=GPIO4, SDA=GPIO5. - pwm on RaspberryPi Pico
Slowly blinks the LED on the Pico with a smooth blinking using PWM. - random on RaspberryPi Pico
Showcases how to use the internal random generator. - spi master on RaspberryPi Pico
Showcases how to use the SPI host controller. - squarewave on RaspberryPi Pico
Showcases how to use the PIO to emit a basic square wave. - uart on RaspberryPi Pico
Showcases how to use the UART together withstd.log. - usb device on RaspberryPi Pico
A really basic example for a raw USB device. You can use the Python 3 scriptscripts/usb_device_loopback.pyto test the USB device. - usb hid on RaspberryPi Pico
A really basic example how to implement a USB HID device. You can use the Python 3 scriptscripts/hid_test.pyto test the HID device. - ws2812 on RaspberryPi Pico
Showcases how to control one WS2812 LED attached to GPIO23. - tiles on RP2040-Matrix
Showcases how to control the LED matrix on the development board to do a simple color flipper effect.
Flashing
You can flash all examples using either your file browser by dragging the example .uf2 file from zig-out/firmware/ to the directory.
Or you can use picotool to flash a uf2 file:
[user@host] raspberrypi-rp2040/ $ picotool load -x zig-out/firmware/${file}.uf2
Loading into Flash: [==============================] 100%
The device was rebooted to start the application.
[user@host] raspberrypi-rp2040/ $
