Anonymous upper computer V7 waveform display

2022-07-23 12:35:00 【Alone, sir】

Set the corresponding... According to the anonymous upper computer's flexible format frame Frame head

Because the format is relatively simple, the original code is directly pasted for reference （ General debugging pid Both are data comparison and debugging , So I only wrote two functions to send comparison , One int16 And a int32, It's enough ）

Be careful ： Due to the large sending volume, it is best to configure the serial port dma, The procedure here is stm32 Upper
