How to enter ISP (serial port /USB download)
* Method 1:
Press Boot0 and NRST at the same time and
release NRST. After 0.5s, release Boot0 and
enter ISP mode
* Method 2:
In the power off state, press Boot0, power on,
wait for 0.5s, release to enter ISP mode
* Serial port download: use USB to serial port to connect the core board PA9,PA10 can be, do not use USB port power supply
* USB download: use the data cable to connect to the computer, if there is no identification problem,The chip can be properly heated (25°C+),then re-entering ISP mode
* STM32CubeProg, Weact Studio Download Tool (see Github/WeActTC/MiniSTM32F4x1/Soft/)

WeAct Studio HID Flash

* No USB to serial port, no debugger, no computer driver, just a Type-C data line can complete the firmware download
1. Burn HID IAP firmware (the factory program
brushes in by default, which is a special test
version)
2. Press the KEY KEY to power up or press the
KEY to reset, LED C13 flashes, release the KEY
to enter
3. Confirm APP firmware address is 0x8004000,
interrupt address offset is 0x4000
4. Download it using
