Abstract

The invention provides a program downloading device, which comprises a reset button, a mode selection switch, a jumper interface, a first DB9 interface and a second DB9 interface, wherein the data pin of the first DB9 interface is connected with the data pin of the second DB9 interface through the jumper interface; the first DB9 interface is used for connecting with a computer serial port; the second DB9 interface is used for connecting with a target board card; the reset button is connected with the second DB9 interface for generating a reset signal; the mode selection switch is connected with the second DB9 interface and is used for selecting a single chip microcomputer as a BOOT mode; the STM32 single chip microcomputer of the target board card is reset to the BOOT mode directly through a toggle switch to carry out program downloading, level reset does not need to be set through a computer, and a program downloading operation process is simplified.

Description

technical field [0001] The embodiment of the present invention relates to serial embedded development technology, in particular to a program downloading device. Background technique [0002] At present, the program download method of the STM32 series single-chip microcomputer based on STMicroelectronics is all downloaded through the RS232 interface using the BOOT mode. To connect, you need to solder each wire at one end of the serial cable to each pin of the STM32 microcontroller, and then apply a high level to the BOOT pin through the computer, so that the STM32 microcontroller restarts and enters the BOOT mode to download the program. After the download is complete, remove the serial cable. [0003] However, when there are many boards of this type, it is necessary to add a high level to the BOOT pin through the computer every time to download the program, and the operation process is cumbersome. Contents of the invention [0004] The program downloading device provided...
