1. Learning objectives
Read the pressed state of key KEY1.
2. Experimental preparation
As shown in the figure below, key KEY1 is an onboard component, so no external devices are required.
3. Core code analysis
To read the pressed state of a key, we judge by reading the data at address 0x0d:
read_data_array(0x0d, 1)
Parameter explanation: Read the status data of a key
0x0d: the address of the key, 1: read 1 byte.
Return value: 0: means the key is not pressed, 1: means the key is pressed.
Source code path: project_demo/03.Basic_car_course
4. Experimental phenomenon
Turn on the robot, open the computer browser to enter the Jupyter lab editor
Enter the source code path, double-click the code to be run
Restart the kernel and clear all outputs
Click the first code block, then click the run button to start running one by one
After the program runs, as the code block runs, we press the KEY1 button on the car, and a prompt will appear on the jupyter lab as shown below
