I used ATMEGA8 and 16M crystal to write a CTC mode frequency generator: I then used a key to control OCR1A to control the frequency generated by OC1A pin. I found that when the frequency of OC1A pin w...
[p=28, 2, left][color=rgb(0, 0, 0)][font=微软雅黑,][size=3][backcolor=white]The switching speed of a transistor is characterized by its switching time. The shorter the switching time, the faster the switc...
I would like to ask, after receiving a PCB file, how can I tell at a glance whether there is a cup hole in it? It seems to be a blind hole. The pad for the cup hole is generally an arc shape. The cup ...
Recently I saw the iic adapter driver in 2410, and found that s3c24xx_i2c_doxfer first turns on the interrupt at the beginning of the transmission, and then turns off the interrupt after the interrupt...

1. Function and purpose There are two pins BOOT0 and BOOT1 on each STM32 chip. The level status of these two pins when the chip is reset determines which area the program starts from after th...[Details]
DMA： 1. When using DAC, when the converted analog signal is output through the IO port, why is the IO port also configured to input mode? PS: The stm32 manual defines that PA4 and PA5 are connected...[Details]
T1 or T2 are two timers/counters of MCS-51 microcontroller. The first method can use two timers/counters to generate rectangular waves. In order to save interface resources, the second method is used...[Details]
Assume that the crystal frequency of the microcontroller is 6MHz. It is required to use timer 1 in mode 0 to generate a continuous square wave pulse with a period of 500us, and output it from P1.0. T...[Details]
Design a second and minute pulse generator for a single-chip microcomputer using the interrupt method. Assume that P1.0 generates a positive pulse of one machine cycle per second, and P1.1 generates ...[Details]
