I went to a company (a relatively large one in China), and when they saw my resume, they said: Sorry, we only want people with ARM experience. Sorry. I searched the job market, but basically couldn't ...
Driving a three-phase BLDC/PMSM motor requires varying degrees of intelligence to ensure the correct magnetization sequence is successfully generated. By using a microcontroller, motor drive designers...

The update interrupt initialization configuration of the stm32 advanced timer TIM1 is not much different from that of the ordinary timer. What needs to be paid attention to is the configuration of TI...[Details]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]
The goal of this article is to build a TCP client based on the previous project that can ping the PC, and can actively send data to the PC, and can also send and receive data with the PC, and display...[Details]
The application of millimeter wave technology in mobile communications also involves a series of technical problems, including the large propagation loss of millimeter waves and the susceptibility ...[Details]
The article is written for LPC2148, but it is also applicable to Samsung's 44B0 chip. You only need to select S3C44B0 as the corresponding CPU when selecting it. JLINK debugging experience un...[Details]
As a leading company in automotive semiconductors, Freescale and Khronos Group have jointly launched an automotive multimedia embedded microprocessor i.MX35 with an integrated OpenVG hardware acceler...[Details]
I used the bit definition in my 51 program: bit flag. After defining it this way, I ran the program and downloaded it to the circuit board. I found that the flag was not the value I set, which led to...[Details]
The Vatican Secret Archives is one of the world's greatest historical collections, but many of its documents have never been transcribed. Recently, a project called Codice Ratio used a

As shown in the figure, the author soldered a STM32F207VET6 board using a TQFP (32-100PIN) 0.55MM to direct plug adapter board. The board leads out the SWD debug interface (only PA13 and PA14 are occ...[Details]
Interrupts and timers implement a 24-hour clock. The program is as follows: #include reg52.h #define PORTLEN P0 sbit bit_select = P2^0; sbit seg_select = P2^1; unsigned char src = {0x3f,0x06,0...[Details]
Single-chip microcomputer experiment design: It is required to use 8951 series single-chip microcomputer, design a pulse generator with a pulse width duty cycle of 50%, 25% adjustable, and a period o...[Details]
Arduino programming is easy to learn, but it has to be used with an Arduino control board, which makes it more expensive and bulky. In addition, most circuits other than the microcontroller circu...[Details]
