I use the timer to start the AD conversion. I would like to ask if the timer continues to count after the AD interrupt service subroutine is started, or does it start counting after the interrupt serv...
How to design a circuit, a low-level trigger circuit. If the timing returns to a high level after 0.001s, the camera will not be triggered to take a photo. After the low level lasts for 0.001s, it wil...
I need to use multiple picture buttons in my program, so I overloaded the DRAWITEM of CBUTTON. But I found a problem. When I switch between different buttons, the buttons sometimes appear completely g...
1. When using PCF8563 for timing, there are 4 options for the timer clock source, but I don't know what the selection criteria are. Which frequency do people usually choose? 2. Is the value of the div...
