Package Include

• 1 x Pico Breadboard Kit Plus version

Getting Start

• Install CMake (at least version 3.13), and GCC cross compiler (Raspberry Pi OSis pre-installed by default, other systems please install it yourself.)

sudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi libstdc++-arm-none-eabi-newlib

• Install Pico-SDK in Your OS(like Raspberry Pi OS).

wget https://github.com/raspberrypi/pico-setup/blob/master/pico_setup.sh -O pico_setup.sh
chmod a+x pico_setup.sh
./pico_setup.sh

• Download the demo project directly and build it.

cd /home/pi/
git clone --recursive https://github.com/geeekpi/pico_breakboard_kit.git
Build Projects
cd pico_breakboard_kit/
mkdir build
cd build/
cmake --no-warn-unused-cli -DPICO_OPTIMIZED_DEBUG=1 -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug ../
make -j4

Upload firmware to Pico Unplug Raspberry Pi Pico from Raspberry Pi and press boot_sel button and then connect the Raspberry Pi Pico back to Raspberry Pi. Execute following command to copy the *.uf2 file to Pico.

cp firmware.uf2 /media/pi/RPI-RP2/

After a while, when the firmware has been uploaded to Pico, it will restart automatically, you can test the demo code according to the information on screen. Have fun!

FAQ

• Q: Why is is so slow when I drag the circle ring on screen?

Because of the memory of pico is just 264KB, and graphic interface may consume a lot of memory to show the graphic widget.

• Q: Can I use MicroPython with LVGL to drive the screen?

No, it is lack of memory, so it may stack when you upload the firmware.
