Situation: When using GPRS dial-up, if you unplug the device directly, the network connection icon will take a long time to disappear. I wrote a filter driver and found that there are still data packe...
We may usually only distinguish DSP by the chip model, and rarely pay attention to the letters in the chip suffix, but these suffix letters are sometimes related to our development. I remember that wh...
Abstract: This paper introduces the working principle and functional characteristics of two commonly used APFC chips, UC3854 and UC3855, and makes experimental waveform analysis and comparative resear...
For STM32, there are two ways to reset the software: 1) Use the official software library The system reset function is directly provided in the stm32f10x_nvic.c file of the official software li...[Details]
1. Function prototype In the function library officially provided by STM32, you can find functions like HAL_Delay(). This function uses a timer to achieve a more accurate time delay and provides it...[Details]
In the previous article, I wrote a simple GPIO running light test, which looked a bit monotonous. I was used to serial port debugging. If there was no serial port on the board, I had to find another ...[Details]
