# Picoco
A repository to store Rasbperry Pico C projects.
A repository to store Rasbperry Pico C sample projects.
It uses the **Freenove Super Starter Kit For Raspberry Pi Pico**, the tutorial and ressources can be found [here](https://github.com/Freenove/Freenove_Super_Starter_Kit_for_Raspberry_Pi_Pico).
The official documentation to start with the Raspberry Pi Pico: [Getting started with Raspberry Pi Pico-series](https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf).
The official documentation to start with the Raspberry Pi Pico: [Getting started with Raspberry Pi Pico-series](https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf). Some examples can be found here: [github.com/raspberrypi/pico-examples](https://github.com/raspberrypi/pico-examples).
**NOTE**: the configuration defined in `config/FreeRTOSConfig.h` is specific for the **Raspberry Pi Pico 2 RP2350**. Feel free to update it for your Pico spec.
## Installation
In order to build and deploy the binary in the Raspberry Pi Pico, you have to install the **Pico C SDK** and **Picotool**.
In order to build and deploy the binary in the Raspberry Pi Pico, you have to install the **Pico C SDK**, **Picotool** & **FreeRTOS Raspberry Kernel**.
So, you need to execute the following command that will installed both:
So, you need to execute the following command that will installed all:
```bash
make install
```
**NOTE**: this will install the **SDK** and **Picotool** in the current directory. If you want to set an other intallation path,
**NOTE**: this will install the **SDK**, **Picotool** and **FreeRTOS** in the current directory. If you want to set an other intallation path,
set the `INSTALL_PATH` variable. The `INSTALL_PATH` directory must exists, create it before and make sure user have write rights.
The **SDK** and **Picotool** version used is: **2.1.0**.
