adxl335 vibration sensor-based on stm32G0+ThreadX

Question requirements:
This internship requires development in C language under μC/OS-III or FreeRTOS, RT-Thread embedded operating system (but I used Microsoft's ThreadX. Use an analog output acceleration sensor to collect the vibration status of the equipment. Through RS485 The interface communicates bidirectionally with the PC. The PC side displays the vibration amplitude, acceleration, speed, and vibration frequency, and at the same time can set the working parameters of the acquisition side. The internship content of the
problem analysis
is far-fetched. Such a simple thing requires the use of a real-time operating system, but because of its simplicity. , so you can save some money (referring to using the G0 from the previous garbage collection (laughing). The sensor must use an analog output sensor, and the cost has increased sharply. There are no cheap analog output sensors on the Internet. After checking, I found that there is a sensor on Taobao The store sells adxl330, only 16 pieces, but after placing the order, the seller said it was out of stock, so I had no choice but to order the 20 yuan adxl335 module to remove and use. (Some students may ask: Why not just use the module? Which is more convenient? ————The store told me that the PCB was out of stock after I placed an order.
