STC89C52 singlechip download mode
(1) connections are as follows: (only need 3 lines)
TX USB to TTL small plate connecting MCU P3.0 (RX)
USB to TTL platelet RX connecting MCU P3.1 (TX)
USB to TTL platelet microcontroller GND GND connection
Note: download program is the highest baud rate adjusted to 2400, due to the development board circuit design is different, is meet to download program can try on the TX microcontroller TX, RX MCU RX.
Tip: USB to TTL small plate with single-chip microcomputer or other connection method of the products is:
USB to TTL microcontroller

(2) development board or minimum system using a separate power supply, after good line connection, will find that even at this time development board switch is closed, development board the power indicator light will be lighted (weak), belongs to the normal phenomenon, download or according to the serial port STC89C52 SCM method (power need a cold boot).
STM32 microcontroller download mode:
(1) connections are as follows: (only need 3 lines)
TX USB to TTL small plate connecting MCU PA10 (RX1)
USB to TTL platelet RX connecting MCU PA9 (TX1)
USB to TTL platelet microcontroller GND GND connection
Now basically computer are rarely with serial port, play development board or upgrade some equipment is more trouble, USB to TTL solves this problem very well, don't have to worry about no problem of the serial port of a computer, directly insert the USB, the other end received development board download mouth mouth or equipment upgrades.
The adapter plate adopts imported CH340G USB to TTL chip, this also is the most common use is also the most use of a single chip.
In order to see the board USES a very compact and reasonable double panel design, with a standard USB connector, with row needle raises output end, connected to the other board is very convenient.
You need to install the driver first, insert the adapter plate after installation, this time will pop up installation tips, automatically after the success of the installation, open the device manager to check the COM port, as shown in figure:
Open the download software, sets the serial number to the number of face to face, such as graphic:
OK, after the above Settings, can be downloaded to start debugging.
Tip: USB to TTL small plate with single-chip microcomputer or other connection method of the products is:
