===============================
Raspberry Pi Pico
===============================
The `Raspberry Pi Pico <https://www.raspberrypi.com/products/raspberry-pi-pico/>`_ is a general purpose board supplied by
the Raspberry Pi Foundation. The W variant adds built in WiFi communications.
.. figure:: RaspberryPiPicoW.png
:align: center
Features
========
* RP2040 microcontroller chip
* Dual-core ARM Cortex M0+ processor, flexible clock running up to 133 MHz
* 264kB of SRAM, and 2MB of on-board Flash memory
* Castellated module allows soldering direct to carrier boards
* USB 1.1 Host and Device support
* Low-power sleep and dormant modes
* Drag & drop programming using mass storage over USB
* 26 multi-function GPIO pins
* 2× SPI, 2× I2C, 2× UART, 3× 12-bit ADC, 16× controllable PWM channels
* Accurate clock and timer on-chip
* Temperature sensor
* Accelerated floating point libraries on-chip
* 8 × Programmable IO (PIO) state machines for custom peripheral support
* Built in WiFi radio (Infineon CYW43439)
Serial Console
==============
By default a serial console appears on pins 1 (TX GPIO0) and pin 2
(RX GPIO1). This console runs a 115200-8N1.
The board can be configured to use the USB connection as the serial console.
Buttons and LEDs
================
LED controlled by GPIO0 of the wireless chip (not the RP2040 processor).
A BOOTSEL button, which if held down when power is first
applied to the board, will cause the RP2040 to boot into programming
mode and appear as a storage device to a computer connected via USB.
Saving a .UF2 file to this device will replace the Flash ROM contents
on the RP2040.
Wireless Communication
======================
The on board Infineon CYW43439 supports 2.4 GHz WiFi 4 communications
(802.11n), WPS3 and SoftAP with up to four clients.

GPIO23 Output - WiFi controller enable.
GPIO24 I/O - WiFi controller data line.
GPIO25 Output - WiFi controller chip select line.
GPIO29 Output - WiFi controller clock line.
ADC3 Input - Analog voltage equal to one third of VSys voltage.
Note: ADC3 and GPIO29 share the same pin on the RP2040. If the
GPIO25 line is held high (Wifi controller NOT selected) then a voltage
equal to one third of the VSys voltage with appear on this line and
can be read with ADC3. When the WiFi chip is selected this voltage
will be removed so the line can be used as a clock for data exchange
with the WiFi controller.
Separate pins for the Serial Debug Port (SDB) are available
WiFi Controller GPIO
====================
GPIO0 - Output - On board LED.
GPIO1 - Output - Power supply control.
GPIO2 - Input - High if USB port or Pad 40 supplying power.
Power Supply
============
The Raspberry Pi Pico can be powered via the USB connector,
or by supplying +5V to pin 39. The board had a diode that prevents
power from pin 39 from flowing back to the USB socket, although
the socket can be power via pin 30.
The Raspberry Pi Pico chip run on 3.3 volts. This is supplied
by an onboard voltage regulator. This regulator can be disabled
by pulling pin 37 to ground.
The regulator can run in two modes. By default the regulator runs
in PFM mode which provides the best efficiency, but may be
switched to PWM mode for improved ripple by outputting a one
on the wireless chip's GPIO1 (not the RP2040's GPIO1).
