The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
OSC_IN and OSC_OUT are external crystal pins by default. If you do not use an external crystal oscillator on the STM32, how to connect OSC_IN and OSC_OUT If you use the internal RC oscillator instead...[Details]
I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
The first one is a DMA mode of multiple channel acquisition void ADC_DMA_Config(void) { ADC_InitTypeDef ADC_InitStructure; RCC_HSICmd(ENABLE); while (RCC_GetFlagStatus(RCC_FLAG_HSIRDY) == RESET); ...[Details]
1. Common knowledge about DMA. 1. Function: to achieve high-speed data transmission between chips. That is, it can achieve data transmission without occupying the CPU. 2. Mode: There are three tran...[Details]
Title: Use two dynamic digital tubes to display from 0 to 60, output from the P1 port of 89C51, without adding a decoder, and directly connect the digital tubes. Note that they are dynamic digital tu...[Details]
Requirements: Set timer T1 as an external event counter, count 500 pulses every time, then switch T1 to timing mode and output a positive pulse with a width of 10ms at P1.2. Over and over again. A...[Details]
Qinghai has successfully developed two megawatt-class photovoltaic grid-connected inverters. The Qinghai Photovoltaic Research Center has undertaken the national "863" project and has made many r...[Details]
A transformer is an electrical device that can change the AC voltage while keeping the AC frequency unchanged. In the power transmission and transformation process of the power system, the transfor...[Details]
