When learning about stm32f103, I found that most of the online methods use DMA to achieve multi-channel and continuous conversion. Now I want to use interrupts to achieve ADC multi-channel and continu...
Automatic street light control circuit This device can automatically turn on the street lights at dusk and automatically turn off the street lights at dawn, achieving automatic control of street light...
I use timer 4 to count in timer 1 interrupt, sample AD channel 6 once in timer 4 interrupt, and sample AD channel 5 again when the program runs to timer 1 interrupt. At this time, the program will be ...
[size=3][b]Last weekend, I debugged a simple capacitive slider experiment on the 430boost-NOKIA1202LCD board. It is actually quite simple. The PCB capacitive slider on my board is based on the officia...
Finally I have some time to take a break, so I'd like to show off my board. 1. The hardware configuration of the PPLive box motherboard is very powerful, single-core A9, 1G DDR3 memory, 4G storage, on...
