As photovoltaic power stations come into people's view, people are paying more and more attention to them. Recently, some netizens asked me how to match the inverter and components of photovoltaic ...[Details]
At the beginning, I used the stdlib library. Recently, I found that the cube library is more and more widely used, so I started to use the cube library to complete the ADC multi-channel acquisition e...[Details]
STM32 has two watchdogs: independent watchdog and window watchdog. This article mainly introduces the use of independent watchdog. Independent watchdog (IDWG): driven by an independent 40KHZ low-sp...[Details]
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]
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]
Summary of STM32 peripheral DMA usage: 1. Select DAM mode according to your needs: (1) Circular mode—DMA_Mode = DMA_Mode_Circular (2) Normal mode—DMA_Mode = DMA_Mode_Normal 2. For Chanel3 of DMA1, t...[Details]
ADC: 1. The ADC module inside STM32 has three ADC1, ADC2, and ADC3, which are independent of each other, so synchronous sampling can be performed. 2ADC input clock must not exceed 14MHz, it is genera...[Details]
