In daily SMT production, we occasionally encounter PCBA data with unconventional angles (non -0, 45, 90, 180, etc.). When we encounter such data, it is quite troublesome when we do panel assembly.Is t...
Last time, I posted a post about the inaccurate heart rate measurement of max30102. In the last question, the measured heart rate was between 100-500, the waveform was relatively large, and the heart ...
I am a newbie in STM32. Recently, I want to use F4 to read the data stored in the device through the host USB port. After a quick look, I found that after the high-speed USB port is connected to the c...
