Mainly due to the following issues:1. What is the default ACLK setting of the board? Is it the internal crystal oscillator?2. The temperature measurement example given by TI uses CCR0 of TimerA to sim...
Now, I have a jpeg file that needs to be packaged into mms format for sending. How to do it? I don't want the smil format, but the details of the package format (package format). Because it is used on...
It's snowing again, a rare snowfall. In the previous snowfalls, everyone generally said that the snowfall in the circle of friends was the heaviest:pleased: This may be the last snowfall in Beijing th...
In the process of functional verification, usually 60% of the time is spent on test platform development and debugging, and the remaining 40% of the time is spent on test platform construction and cov...
The purpose of this application note is to describe the procedure used to determine the power handling capability of the LFCW series LTCC low-pass filters due to thermally related failures.LFCW series...
I wrote a small driver for the 2.4 kernel. After loading it, I found that the init initialization process was not executed. I would like to ask the reason static void spi_drv_interrupt(int irq, void *...
Wang Xiaochuan, the "Wudaokou Goalkeeper", is going through a level that he has never gone through before. For example, Sogou's (NYSE: SOGO) financial report, artificial intelligence, and the futur...[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]
I recently upgraded MDK to V5.25 and found that there are many libraries in the Managing Run-Time Environment. Compared with the past, it is much better, from the bottom-level driver to the upper-le...[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]

With the development of information technology, intelligence, informatization and networking have become the development trend of modern industrial control. Since the 1980s, the rapid development...[Details]
In order to strengthen the traceability management of recycling and utilization of power batteries for new energy vehicles, and to standardize and guide all relevant parties to fulfill their tracea...[Details]
The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[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]
The photovoltaic industry has become a new business card for China to the world. It not only represents China's leading technology, but also constantly breaks various records with its development spee...[Details]
The STM8L contains a 12-bit ADC with 25 input channels, including an internal temperature sensor, an internal reference voltage As can be seen from the figure above, there is an internal re...[Details]
Summary of STM32 peripheral DMA usage: 1. Select DAM mode according to your needs: (1) Circular mode—DMA_Mode = DMA_Mode_Circular (2) Normal mode—DMA_Mode = DMA_Mode_Normal 2. For Chanel3 of DMA1, t...[Details]
T1 or T2 are two timers/counters of MCS-51 microcontroller. The first method can use two timers/counters to generate rectangular waves. In order to save interface resources, the second method is used...[Details]
