There is an A/D module . One analog input generates a 16-bit digital output . The average value of the 8 outputs before the tth (t=8) th clock needs to be calculated . How many sequential logic units ...
This white paper provides an overview of the WiMAX certification process and the value that certification brings to network operators and vendors. The first section begins by discussing the role that ...
I have studied driver development for two months and read a lot of materials. I have made some simple driver examples (made by ds). Now I have a PCI modem card, but I don't have a datasheet (I have se...
I want to switch to embedded development if I have the chance, but I have no idea about this. Let me ask you a question. For example, if there is a machine for growing plants, how can I maintain the t...
I just replied to an email, but when I checked, I found that the reply time was 8:05 in the morning. :puzzle:
The pictures are as follows:But it’s four o’clock in the afternoon now?[[i]This post was l...
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 the war without gunpowder between China and the United States,
ZTE
has become a new victim. The seven-year chip ban by the United States has pushed this communications giant to a life-or...[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]
I have read the source code of mbed these days, and the interface encapsulation for upper-level application calls is quite good. The code quality is relatively high, the comments are also very detai...[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]
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]
Friends who work in the photovoltaic industry, do you still remember the hard work on June 30 last year? How many people worked late into the night for months in a row just to connect to the grid a...[Details]
1. About FPU transplantation As long as the chip has FPU function, the use of FPU is generally enabled by default. You can also select it in the Options tab; 2. About the transplantation of DSP li...[Details]
Regarding the PHY construction of LWIP, the PHY chip used is LAN8720A, RMII mode. Regarding the hardware connection part, the Atomic board F407 is used, and the hardware connection is as follows: ...[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]
Serial Port: 一. USART_ITConfig(USART1, USART_IT_TXE, ENABLE): As long as the transmit register is empty, there will always be an interrupt. Therefore, if you are not sending data, turn off the tran...[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]
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]
