[Verified]DAPlink 0254

Overview

The original project address is: [https://oshwhub.com/jixin002/stm32f103c8t6_cmsis-dap](https://oshwhub.com/jixin002/stm32f103c8t6_cmsis-dap)

## Function
- Adjust the interface to TYPE-C
- Add 1.8V function (It is not automatically recognized, see [circuit board description] (#circuit board description))
- The original firmware is relatively old, upgraded to 0254, supports WEBUSB
- RST does not have an internal pull-up, it needs to be grounded when upgrading, and needs to be turned on when using the debugging function Pull
## Document description
- DAPLink-0254.rar Adapted 0254 version code (can be compiled and downloaded directly). No need to build a DAPLINK build system
- DAPLink 0254 Developers Guide.pdf Build a DAPLINK build system

## Circuit board description
- Connect U10 , do not connect R9, the circuit works at 1.8V
- connect R9, do not connect U10, the circuit works at 3.3V
- debug state needs to short-circuit RST to 3.3V, no further research

Output waveform problem of integrator circuit
The figure is an ideal integrator circuit. Due to the inverse relationship between the output and the input, in case (1), when the input is a constant DC quantity, the output is as shown in the figure

DSP fixed-point operation function set implemented in C language
This code is compiled with vc6.0 to implement fixed-point operations, including addition, subtraction, multiplication, division, some nonlinear operations, and a fast table lookup algorithm for log.
Why does this problem occur when entering the course?
I used to be able to enter the course directly after clicking on it. What do I need to enter here? I tried using my own account but it doesn’t seem to work…
I want to make an electronic counter. Can anyone provide me with a circuit diagram or finished product?

The plane in the hometown park was severely damaged!
I went back to my hometown recently and visited the city park. I saw that the old planes were all destroyed beyond recognition. What a pity! ! ! ! !
