Because when simulating in protues, the power supply and grounding parts are hidden, I don’t know how to connect the isolated power module, how to design a power isolation module......
[size=4] About the signal input mode selection of the power amplifier. In professional audio engineering, we often encounter problems such as signal parallel connection and bridging. First of all, we ...
I want to organize people in the forum to make some videos, but I hope there is a good video recording software.lilong8470 recommended Screen Recorder Expert, but it seems that Youku cannot support th...
Recently, when calling the Aurora 8b/10b IP module, everything was normal when simulating with the modelsim function . However, when it was downloaded to the FPGA board, the signal that the channel_up...
In this example, TPS54360 is used as a power supply, requiring an input voltage of 55V, an output current of 3A, and an output voltage of 24. 1. Open the device page [url]http://www.ti.com/product/tps...
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]
The trade war between China and the United States has become the focus. The United States has begun to play the ban card against Chinese technology companies. The ZTE incident shows that if the ban...[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]
introduction In the general project development process, two or more microcontrollers are often required to communicate to complete data transmission. For example, a quadcopter wirelessly transmits d...[Details]
After studying the F4 FSMC method to drive the touch screen for a few days, I have gained some understanding, which are listed below. The unorganized record is only for my own reference in the future...[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]
STM32 uses FSMC to read and write CPLD programs. CPLD is hung on the address line and data line of STM32. CPLD is regarded as an off-chip RAM for reading and writing. On the board I made, CPLD is hun...[Details]
This paper proposes a design scheme for an embedded CNC system based on ARM and FPGA. The software and hardware design of the ARM system, the implementation method of hardware fine interpolation ...[Details]
