CH340C-TYPEC-Serial port burning tool

Overview

2022-6-18 Additional note: If the prompt "Computer cannot recognize" pops up after connecting to the computer, please carefully check whether the TYPEC interface is cold soldered (I soldered a few more today, and one of them is this problem).

There are many open source projects about the burner, so I won't say much.

Preface: The first burner I used was one end plugged into the USB port of the computer (as shown below). When using it, you may need a long DuPont line to connect to the microcontroller.

So I drew this board:

You can connect the computer USB port to TYPEC through a data cable, and connect the other end to the burning hole or DuPont line through a pin header to connect the microcontroller to complete the burning.

Actual use (burning diagram):

I lead out two GNDs to facilitate IO0 grounding. Please adjust the lead-out according to your actual needs when using it.

STM interrupt problem
I have encountered a problem.PE0 and PE1 are used as external interrupt sources 0 and 1 respectively.The current problem is that no matter whether PE1 or PE0 is triggered, both interrupts are triggere
How to determine if calls and text messages are received when WinCE is connected to a GPRS network?
When WinCE is connected to the GPRS network, how can I tell when there is a new call or text message? I can hear WinCE make a "ding" sound when there is a new call, but I don't know which program made
Simple task scheduling system
I wrote a small scheduling system out of boredom. It can be run directly on launchpad. If you like it, you can download it and see the effect.
