Template: Pico Kit B Guides
Software Setup
Please follow the guides of Raspberry Pi to install and set up Pico for the Pico.
For easy use, we recommend you use the Thonny tool.
- Thonny website
- Please set the Thonny development environment to be RaspberryPi when setting
Hardware Connection
Please take care of the direction when you connect Pico, an USB port is printed to indicate. You can also check the pin of Pico and the LCD board when connecting.
You can connect the display according to the table.
LCD | Pico | Description |
VCC | VSYS | Power Input |
GND | GND | GND |
MPU.INT | GP2 | INT pin of MPU9250 |
LPS.INT | GP3 | INT pin of LPS22HB |
SDA | GP6 | SDA pin of I2C |
SCL | GP7 | SCL pin of I2C |
FSYNC | GP22 | FSYNC pin of MPU9250 |
Connect the expansion board
Download the examples
Open a Raspberry Pi terminal and run the following commands:
sudo apt-get install p7zip-full cd ~ sudo wget https://www.waveshare.com/w/upload/c/c5/Pico-Kit-B-code.7z 7z x Pico-Kit-B-code.7z -o./Pico-Kit-B-code cd ~/Pico-Kit-B-code cd c/build/
How to use
C Example
Go to the directory of C example and build it
cd ~/Pico-Kit-B-code/c/
Create the build folder and enter it. add the SDK:
../../pico-sdk #should be the path of the SDK according to the actual situation.
We have created the build folder in the example, you can just enter it.
cd build export PICO_SDK_PATH=../../pico-sdk (Note: Please check if you set the correct path of SDK, it maybe different for different users)
Run cmake to generate the Makefile
cmake ..
Run make to build the example, it will takes minutes.
make -j9
uf2 is generated after building.
Press and hold the button of the Pico board, and then connect the Pico to your Raspberry Pi or PC by USB cable, then release the button. Then copy the main.uf2 file which is saved in the build folder to the Pico (It should be recognized as a portable drive, which is named RPI-RP2).
Python example
Work with windows PC
- 1. Press and hold the BOOTSET button of Pico, and connect the Pico to your PC by USB cable. Release the button if the Pico is recognized as a portable drive.
- 2.Copy the rp2-pico-20210205-unstable-v1.14-8-g1f800cac3.uf2 from the python directory to the Pico.
- 3.Open Thonny IDE (Note: Please use the newest version).
- 4.Click Tools->Options->Interpreter and choose the Port of Pico (you can check it in the Device Manager).
- 5. Click File->Open..., choose Raspberry-Pi-Pico-Kit-B.py, and run it.
Working with Raspberry Pi
- 1.The steps to download the firmware is the same as Windows PC. Copy the rp2-pico-20210205-unstable-v1.14-8-g1f800cac3.uf2 to Pico.
- 2.Open the Thonny IDE in Raspberry Pi(Menu -> Programming -> Thonny Python IDE , you can check the version information in Help->About Thonny make sure that it is the version which support Pico.
- 3.Click Tools -> Options... -> Interpreter to choose the MicroPython(Raspberry Pi Pico and the ttyACM0 port.
Please update the Thonny IDE if the pre-installed one doesn't support Pico.
sudo apt upgrade thonny
- 3.Click File->Open...->Pico-Kit-B-code/python/Raspberry-Pi-Pico-Kit-B.py and run the codes.
Expected result
- 1. The LCD keeps blank if you didn't run the demo codes;
- 2. After running the codes, the LCD turns on and displays the data which is collected by the Pico-10DOF-IMU.
