Push-down magnetic levitation_open source

Overview

This project uses the STM32f103c8t6 microcontroller as the controller and has the following features:
1. Use the Type-C (USB-C) power supply interface and use the CH224KPD deception chip to deceive the 12V supply voltage.
2. Use the 7805 linear voltage regulator to provide 5V voltage to the Hall. Sensor, LM324 power supply
3. Use MIC5219 linear regulator to provide 3.3V voltage to power STM32
4. Use LM324 chip to amplify the analog signal to match the STM32 analog pin sampling (ADC), and use the DMA module for data transfer
5. Use the one-dimensional Kalman filter algorithm to filter the collected analog values (to be verified)
6. Use the PID controller for control
7. Use the Bluetooth serial port to cooperate with the host computer to adjust the parameters of the PID controller and display the relevant parameters (to be verified ) Implementation)
8. Use IR2104 and PMLL4148L to form an H-bridge actuator

ucosIII Chinese translation
I just found the uCOSIII information on the Internet. If you don't want to read the English manual, you can borrow it. HahaThere are multiple files, the list is as follows:
How is the non-maskable interrupt input from the OMAPL38 NMI pin (J17) handled?
OMAPL138 has an NMI (J17) pin, which should be a non-maskable interrupt according to the name. ARM interrupts are managed by the interrupt controller. Is the interrupt of this NMI pin sent to the ARM
Dizzy! ! ---- STM32F429 ADC trigger problem.
I have always been confused about the ADC of STM32F429, and I still don't understand the HAL library. I copied the ADC_RegularConversion_DMA routine in ST's HAL library, which uses ADC_EXTERNALTRIGCON

Failed to register COM control on wince?
Failed to register mscesocket.dll on wince, error "Registration functions are not exported from %s". Why is this? Can someone explain it to me?
How to call Media Player in WINCE
This is my first time using WINCE. I have a basic question: how to call Media Player in WINCE? Could anyone help me? Please provide some sample source code. It should be in C#. I would be very gratefu
