The WM signal is a digital signal with a fixed period and an indefinite duty cycle.If the counter of Timer_A works in the up-counting mode, the output adopts the output mode 7 (reset/set mode)to contr...
Because the op amp is powered by a single power supply, a bias voltage VCM1 of tens of mV must be added (why?). I see that the classic differential amplifier circuits are all grounded? Also, I used a ...
1. Introduction
In the last post, I wanted to test the production program, but after consulting and posting, I seem to know that the program is not included when it leaves the factory. Today, I will p...
