Working Principle
The STC Auto Programmer converts USB communication from a computer into TTL serial signals required by STC microcontrollers. During programming, the official STC software communicates with the programmer, which automatically resets the target microcontroller and transfers the compiled firmware through the UART interface.
This automatic download process eliminates the need for manually resetting the microcontroller before each programming cycle, improving development efficiency.
