Product Description:
The USB to TTL downloader can be used as serial communication, microcontroller downloader, STM32 downloader, routing download, etc. This downloader has a USB interface, which can easily extend the download line, and reserve a pin header interface to facilitate short-distance download and plug.
STC microcontroller download mode:
1. The wiring is as follows: (only 3 wires need to be connected)
The TXD end of the USB downloader -> connect to the microcontroller P3.0 (RX)
The RXD end of the USB downloader -> connect to the microcontroller P3.1 (TX)
GND terminal of USB downloader -> connect to MCU GND
2. The development board or small system is powered by a separate power supply. After connecting the line, you will find that even if the development board switch is turned off, the development board power indicator will light up (weakly), which is a normal phenomenon, or download STC according to the serial port. Serial microcontroller method download (power needs to be cold-started once).
STM32 microcontroller download mode:
1. The wiring is as follows: (only 3 wires need to be connected)
TXD end of USB downloader -> connect to MCU PA10 (RX1)
RXD end of USB downloader -> connect to MCU PA9 (TX1)
GND terminal of USB downloader -> connect to MCU GND
2. The development board or small system is powered by a separate power supply. Or use a USB downloader to provide 5V power supply. When downloading, you need to connect boot0 to VCC output. After the download is completed, connect it to GND and press the reset button to complete the operation.
Support win7 32-bit, 64-bit operating system, support win xp operating system
