I plan to use TIM+DAC to achieve this. Use TIM2 to adjust the frequency and generate a square wave. TIM3 is a single pulse in slave mode, adjusts the pulse width, and is triggered by TIM2.This step is...
In March 2013, the first National Sensor Technology Application Conference and China Sensor Technology Engineers Annual Conference organized by the China Electronics Society will be held in Beijing. T...
Why are there more posts about STM microcontrollers in the forum and fewer posts about LPC microcontrollers? Is it because STM microcontrollers are used more than LPC microcontrollers?If I want to get...
I am working on a Modbus host program recently and need a software that can simulate the slave. I am currently using ModSim, but it cannot control the response delay. Does anyone have any good softwar...
Seoul, June 5 (Reporter Tai Ju) Yonhap News Agency reported on June 5 that Korean researchers found in a human experiment that electromagnetic waves emitted by CDMA mobile phones can change the physio...
Photovoltaic inverters are the core equipment of photovoltaic systems. Their main function is to convert the direct current generated by photovoltaic modules into alternating current that meets the...[Details]
In our common sense, the word technology often has two definitions. The first is the technology sealed in the laboratory. They are like flowers on the mountain top. Only a few people on the mountai...[Details]
The status of interrupts in developing embedded systems is absolutely unquestionable. In the era of C51 microcontrollers, there were only 5 interrupts, including 2 external interrupts, 2 timer/counte...[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]
In 1952, Bell Labs built a 6-foot-tall automatic number recognition machine called "Audrey", which could recognize the pronunciation of the numbers 0 to 9 with an accuracy of more than 90%. And its...[Details]
Although it is early summer, the Chinese smartphone market is still in the cold winter, just like Beijing in April with snow. For mobile phone brands caught in the middle, the cold is even more bit...[Details]
This example is mainly to familiarize yourself with the register configuration of Timer A and the configuration method of IAR. /*********************************************** Program function: re...[Details]
This is a "cooperation" that is related to the future development of China's semiconductor industry. Let's follow the embedded editor to learn more about the relevant content.

I have been working on a stm32 project recently and have been struggling with its startup method. I saw a good article and reposted it. The format of the original article is not very good, and there...[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]
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]
In 2014, the production and sales of new energy vehicles in China exceeded 80,000 units, and the development trend is encouraging. In order to enable new energy enthusiasts and junior R&D personnel t...[Details]
