I. Preface
Just now, the courier sent AT32F403 single-chip microcomputer, which was sent by Artery technicians. In order to better apply the single-chip microcomputer in the future, the following circuit board is made to conduct a preliminary test of the development tool chain of the single-chip microcomputer.
2. Circuit design
Design the test circuit, use SWD for program download, and add an LED to the outside to display the status of the IO. Design a single-sided circuit board that is suitable for one minute board making and one minute later to get a test board. The board is perfectly made. Weld it below.

The circuit board is soldered, cleaned and then debugged. Use AT-LINK to link the board. A probe clip is used to introduce the debugger and power supply into the board. The following is a test using ICP software to see if the circuit can be debugged.
After testing, the ICP software can be connected to AT-LINK, which lays the foundation for later software development. The following is a simple test program to test whether the LEDs on the circuit board and the serial port are working properly. Or use the AT32 microcontroller Workbench software to generate the software framework. Once compiled, download it using ICP. The board is working fine, operating at 240MHz and nearly 70mA.
Now, though, a strange problem has been encountered. Just now using the ICP software can download the program normally. But in the Keil environment, there was a problem. Download the program, the system prompts an error. It is not yet known which part is the problem. Later, I will ask for the help of Artery technicians.
※Summary※
In this article, the AT32 microcontroller that has just been received is tested. Using ICP and AT-LINK, the program can be downloaded from the microcontroller. But in the Keil environment it ran into problems. Program downloads are not possible. Later, we will seek the help of Artery technicians.
