The most significant event in the technology circle during this period is undoubtedly the news that ZTE was banned by the United States. Once the news came out, it shocked the entire Chinese techno...[Details]

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]

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]

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]

1. The first project We are going to create the first project, which is mainly for project analysis, so that we can understand how CubeMX works and how to trace the code logic. Okay, no more nonsense...[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]

This routine is also a classic routine on the development board. I modified the framework of the program to make it more suitable for future calls. The specific 4*4 keyboard scanning principle is rel...[Details]

In the project, CPLD is needed to complete part of the algorithm design. The parameters are given by AVR, so the communication between AVR and CPLD needs to be completed. Therefore, a test program is...[Details]

According to TechRadar, given rumors that Google is developing a Pixel Watch , the recently renamed Wear OS smartwatch operating system may soon be able to show its full cap...[Details]

    //Observe the difference between feeding the dog and not feeding the dog, and use the LED indicator of the PB port for status indication.     //Switch the LED indicator enable switch of the PB po...[Details]

Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[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]

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. Last week, a...[Details]

A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]

Here is the temperature added in the previous chapter The above figure is the temperature calculation formula: where Vsense is the ADC value collected from the temperature channel. The stm32f407 ...[Details]
