# Development kit: Raspberry Pico
|
|
|
|
This is the official development kit. It offers the following advantages:
|
|
1. Low cost
|
|
2. Parts are easy to find
|
|
3. Low wiring/soldering: usage of a motherboard
|
|
4. SWD debug port
|
|
|
|
Current status: ON DEVELOPMENT
|
|

## Bill of materials
|
|
|
|
The minimal list of components are:
|
|
|
|
| Part | Price | Shop |
|
|
| ----------------------------------------- | -------- | --------- |
|
|
| Audio board + speaker | 13 € | Waveshare |
|
|
| Raspberry Pico W | 9 € | Kubii |
|
|
| 2inch LCD (320x240) | 14 € | Waveshare |
|
|
| Some Pimoroni buttons are rotary switches | 4 € | Pimoroni |
|
|
| UPS module or Pimoroni LiPo Shim | 15 € | Waveshare |
|
|

|
|
| **TOTAL** | **67 €** |
|
|
|
|
In addition to this list, you may need some more materials such as wires, prototype boards, resistors...
|
|
|
|
We may propose in the future a PCB to help the connection without soldering.

# Developers: how to build from the source code
|
|
|
|
## Install build tools
|
|
|
|
Install build tools, example for a Debian based operating system:
|
|
|
|
- sudo apt install gcc-arm-none-eabi
|
|
- sudo apt install picolibc-arm-none-eabi
|
|
|
|
Download the pico SDK somewhere on your disk:
|
|
|
|
```
|
|
git clone https://github.com/raspberrypi/pico-sdk
|
|
```
|
|
|
|
|
|
|
|
Copy past the following command line, execute at the directory root. Replace the PICO_SDK_PATH value with the real location on your disk where you have installed the Pico SDK.
|
|
|
|
First, create a CMake build directory:
|
|
|
|
```
|
|
mkdir build
|
|
cd build
|
|
```
|
|
Then generate the makefile (we use the Pico toolchain here, so there is no specific toolchain file to setup.)
|
|
|
|
```
|
|
cmake -DCMAKE_BUILD_TYPE=Debug -DOST_BUNDLE=RASPI_PICO -DPICO_SDK_PATH=../pico-sdk -DPICO_BOARD=pico_w ..
|
|
```
|
|
|
|
This assume that the Pico SDK is located on the git project root directory. Change this path according to your real Pico SDK location.
