# 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
|
|
|
|
Here is an example of components.
|
|
- Links are examples of what to buy, price is not optimized
|
|
- Use traditional suppliers for generic components (buttons, resistors...), such as Adafruit, PiHut, Pimoroni, Kubii, Gotronic...

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.
