Servo motors are widely used in servo systems as an actuator of mechanical equipment. When we use servo drives, we sometimes feel that the motors generate a lot of heat when they are working because w...
Let me ask a simple question. I use 52 to control 220V AC power through 74hc14/12V relay. Because two AC power lines are controlled at the same time, that is, two sets of relays, when I close one line...
Use 74LS194 (shift register), 74LS138 (3-8 decoder), 74LS20 (NAND gate), 74LS74 (D flip-flop). Design an accumulator. How should I design it? I can't figure it out no matter how hard I try. Especially...
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]
Recently, the " ZTE

caused by the Sino-US trade war
has caused heated discussions in the electronics industry. It not only reflects that Chinese companies are lagging behind in the...[Details]
In Windows environment, the source code is encoded in UTF-8. If the source file created by STM32CubeMX contains Chinese comments, then using STM32CubeMX to regenerate the source code will cause the C...[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]
Leading Chinese PV inverter manufacturer Huawei said it is supplying string inverters to a 75MW fully digital utility-scale solar project in Brazil, which it claims is the first of its kind in the cou...[Details]
According to foreign media reports, the 2018 GMC Terrain Denali is equipped with multiple collision detection systems, and a recent test verified the safety of the system. Even when driving in a bu...[Details]
In the project, CPLD is needed to complete part of the algorithm design. The parameters are given by AVR, so the communication between AVR and CPLD needs to be completed. Therefore, a test program is...[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]
WPG Holdings announced that its subsidiary Youshang has launched a wireless smoke alarm solution based on STM and Semtech . With the development of the national economy and the enhancement of...[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]
The STM32 watchdog has two WWDG and IWDG. The biggest difference between the two is that IWDG has only one lower limit for feeding, while WWDG, as the name implies, must be fed within a range to ensu...[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]
1) ADC multi-channel acquisition: (Multi-channel acquisition must use scanning mode. In scanning mode, the channels of the rule group share a register, so DMA transmission must be used; to prevent da...[Details]
