Lokum_RP2040
Small programs examples for RP2040 Microcontroller ( Raspberry Pi Pico )
About RP2040
RP2040 is a low-cost, high-performance microcontroller device with flexible digital interfaces. Key features:
- Dual Cortex M0+ processor cores, up to 133 MHz
- 264 kB of embedded SRAM in 6 banks
- 30 multifunction GPIO
- 6 dedicated IO for SPI Flash (supporting XIP with it is a feature used in the 'boot from flash' type of application. XIP mode enables execution of code from serial SPI flash instead of the more traditional way of executing the code from memories such as DDR/SRAM)
- Dedicated hardware for commonly used peripherals
- Programmable IO for extended peripheral support
- 4 channel ADC with internal temperature sensor, with 0.5 MSa/s (the MSa/s means MegaSAmples per Second which it is a measurement of sampling rate in millions of samples per second, here means 5k samples/s ), 12-bit conversion
- USB 1.1 Host/Device

Install tools
Linux
Open terminal and write:
1- Get the script (if you do not have wget yet install it by: sudo apt install wget):
$ wget https://raw.githubusercontent.com/raspberrypi/pico-setup/master/pico_setup.sh 1
2- Make the script executable:
$ chmod +x pico_setup.sh
3- Run it:
$ ./pico_setup.sh
4- Reboot your system when the install is done:
$ sudo reboot
The script will:
• Create a directory called pico
• Install required dependencies
• Download the pico-sdk , pico-examples , pico-extras , and pico-playground repositories
• Define PICO_SDK_PATH , PICO_EXAMPLES_PATH , PICO_EXTRAS_PATH , and PICO_PLAYGROUND_PATH in your ~/.bashrc
• Build the blink and hello_world examples in pico-examples/build/blink and pico-examples/build/hello_world
• Download and build picotool and copy it to /usr/local/bin
• Download and build picoprobe
• Download and compile OpenOCD (for debug support)
• Download and install Visual Studio Code
• Install the required Visual Studio Code extensions
• Configure the Raspberry Pi UART for use with Raspberry Pi Pico
- More on "Getting Started With Raspberry Pi Pico" file
5- on VScode install "cmake-tools":
https://marketplace.visualstudio.com/items?itemName=ms-vscode.cmake-tools
6- Follow docs/How to build to build your project
Serial (to see printf output)
sudo apt install minicom
minicom -b 115200 -o -D /dev/ttyACM0
