How to Enter ISP (Serial/USB Download):
- Method 1: Press BOOT0 and NRST at the same time, release NRST. Release BOOT0 after 0.5S, you can enter ISP mode
- Method 2: In the power-off state, press and hold BOOT0 to power on, wait for 0.5S, and release it to enter the ISP mode
- Serial port download: use USB to serial port to connect to the PA9 and PA10 of the core board, do not use the USB port for power supply
- USB download: Use a data cable to connect to your computer. If there is an unrecognized problem, you can properly heat the chip (25℃+), and then re-enter the ISP mode
- Software: STM32CubeProg, WeAct Studio Download Tool (see data/Soft folder)

How to enter H IDIAP (USB download):
No need for USB to serial port, no debugger, no computer driver. Just a TYPE-C data cable to complete the firmware download
1. Burn the HIDIAP firmware (the program is flashed in by default, which is a special test version)
2. Press and hold the KEY button to power on or press the KEY button to reset, LED C13 flashes, release the button to enter
3. Confirm that the APP firmware address is 0x8004000, and the interrupt address offset is 0x4000
4. Download using Soft/WeAct_HID_FW_Bootloader/WeAct_HID_Flash_xxx.exe
