GALAXYHP’s Liangshan-style smart car

Participate in the smart car training camp jointly organized by Lichuang Development Board and GigaDevice, use Liangshan School development, draw the PCB board according to the tutorials, and initially learn to write and reproduce certain functions through tutorials on basic codes and functional codes. , during the process of verifying the project, I found that the pins of the board I originally drew were wrong, and I started to change the code wildly. A friend who had almost adjusted the program helped me take a look, and the code I changed was just the tip of the iceberg.
When choosing between blacklisting and saving the board, I thought over and over again and decided to use the DuPont cable I bought before to connect the Liangshan faction and the expansion board. That’s why it became what it is now, which is inconsistent with the original idea. Based on this, I have verified functions such as lighting, tracking, and Bluetooth remote control, and achieved good results. However, for some unknown reason, when verifying the final program, functions such as tracking/Bluetooth cannot be switched. This is the best that this car can achieve. Scored.
This experience taught me the lesson of carefully reading the relevant user manual when designing a circuit board.
Since there is not much time left, we will continue to modify the code later and look forward to switching all functions to use.
