"Principles and Applications of Relay Protection in Power Systems" first introduces the basic concepts of conventional protection and microcomputer protection in power system relay protection, and the...
I want to learn about PIC microcontrollers recently. I'm looking to see if anyone in the forum has used a development board that they no longer need and is willing to share it with me. If you are inte...
This design uses MCS51 single-chip microcomputer as the core, and collects data on the ambient temperature through the temperature sensor, so as to establish a control system, so that the electric fan...
Help!!! Waiting online!!! I encountered this problem when burning uboot, which great god knows how to solve it? ? ? Search OK U-Boot 1.3.4 (Dec 22 2011 - 02:26:52) for SMDKV210 CPU: S5PV210@1000MHz(OK...
External interrupts are the lowest priority interrupts of MSP430 and are maskable interrupts. They are relatively simple to use. 1.2.7 Simple port interrupts (external interrupts) All ports of P1 and ...
1. Principle 1. Infrared emission protocol The infrared transmission protocol has been written in the previous article , so I will not repeat it here. 2. Timer counting and input capture A timer...[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]
I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[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]
Use the STM32 timer input capture module to control 3-way ultrasonic sensors. The ultrasonic sensor used this time is the common HC-SR04, which is often used in the obstacle avoidance system of smal...[Details]
When STM32 uses JTMS (PA13) and JTCK (PA14) as normal I/O ports, add the following code before initialization (the order cannot be reversed): RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE); G...[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]
