#The Fifth Lichuang Electronic Design Competition#Intelligent offline downloader

1. Self/team introduction

I like to tinker with code and am more interested in smart products. I use C language more when doing embedded development. I have a certain foundation in using C language. I have used C plus plus when taking on Qt projects. I can’t say I’m proficient. I learn while doing it, and I can experience the improvement of my abilities. I should guard against arrogance and impetuosity, and keep moving forward, hoping to make further leaps and make more interesting things.

2. Briefly introduce the project

This project is purely something I did in my spare time, because usually when we download the program, we connect it to the burning interface on the control board through the computer, and then click download, and the program is burned onto the control board. So if the computer is not around, or the equipment needs to be upgraded outdoors, the computer is inconvenient to carry, or there are a large number of control boards to burn programs, is it necessary to provide each burning person with a computer to burn the program? ? So I searched and found that there is an offline downloader. There are many pins to be connected when burning. In fact, so many pins are not needed, but it is a standard interface. Therefore, I want to make a downloader that uses the serial interface to download. Different from using the jtag interface, we use the bootloader that comes with the microcontroller to upgrade the microcontroller firmware.

1. Describe project details

The project uses the stm32f103 series of microcontrollers. The specific plan is for the user to copy and paste the program to be downloaded from the computer to the offline downloader. Then connect the downloader to the control board where the program needs to be burned, press the download button, and the program will be downloaded to the control board.

2. Describe the challenges faced by the project and the problems solved

The problem that the project needs to solve is how to store the program to be downloaded on the offline burner, and how to burn the program to the control board of the program to be burned.

3. Describe the key points involved in the hardware and software parts of the project

The hardware aspect is the docking method of the interface and the definition of the interface. The software aspect is the storage method and burning method of the program.
