This book introduces the hardware structure, composition principle and instruction system of the MCS-51 series single-chip microcomputer in detail. Combined with application examples, it briefly descr...
I am currently using cy7c68013+FPGA+TVP5150 to make an image acquisition card. I have just finished drawing the schematic diagram of the board. I just need to modify the firmware program with the rout...
I am going to implement the EINT interrupt driver, so I have looked at the Userkey driver in SMDK2440. In the Userkey.cpp file, there is the following function BOOL InitInterruptThread() { ... KeyEven...

Has anyone used the signal amplification circuit of a pressure sensor? I use a pull pressure sensor, which outputs a voltage of 0-18mv under a 12V power supply. I want to amplify the voltage to 0-5v. ...
This article discusses how to wake up a touch-sensitive device such as a tablet without touching the device, using basic gesture recognition and novel proximity sensors. The article discusses the p...[Details]

It is well known to automotive suppliers that automakers are demanding more from their supply base. For connector suppliers, this means stricter requirements for product performance, stability and ...[Details]
The era of mobile access to the Internet has arrived, and it will rapidly change the business and infrastructure needs of mobile operators under a whole new trend of requirements. We need 4G LTE to...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Infrared remote control is widely used in home appliances, but the remote controls produced are not compatible with each other. The universal remote controls commonly seen on the market can only co...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
In recent years, the application of single-chip microcomputer systems in the field of industrial measurement and control has become more and more extensive. However, for industrial sites with harsh...[Details]
