Realize the process of USB_Flash_BootLoader HID to flash the AVR microcontroller chip program

In the early stage of making USBASP, I learned the BootLoader principle of AVR microcontroller chip, found a lot of information about USB-HID and BootLoader, and made a simple atmega8(16) board that can flash the program. Now I will share what I have learned with you. 1. About BootLoader BootLoader means that

MCU pin flip test

The IO port rate of STM32 can reach 50MHz, but when the IO port is used as a read/write signal to read and write data, the flip rate is not that fast. When using STM32 to read digital camera data and write it into TFT, the data transmission rate is involved, and the IO port needs to be flipped quickly. So, I did thi
