[size=12px]I would like to ask: What are the operating systems based on arm9? What are their advantages and disadvantages? What programming languages are used? I am new to these and don't know how to ...
I am designing a simple voltmeter with voice prompts, which will prompt the measured voltage value every certain time (such as 5 seconds). The program is written in C language. The voice module uses t...
[align=left]Our group has always used hardware adjustment in the adjustment of PWM wave. Compared with software adjustment, hardware adjustment is simple and crude in adjustment, but it requires a goo...
[align=left]Those who do motor testing should be familiar with current shunts. We usually choose large-range or small-range current shunts to configure on the equipment. Usually used as an accessory o...
1. Principle 1. Infrared emission protocol There are many infrared communication protocols. This experiment uses the NEC protocol. This protocol uses PWM modulation and uses pulse width to represen...[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]
We have come a long way from the 2G era, and now 5G is about to be commercialized. Suddenly, we realize that time has passed quickly, but technology has never stopped. The activation of 5G heralds ...[Details]
Recently, there was news that the US government asked Google to shut down the Android operating system for ZTE phones. After that, some people even imagined what the consequences would be if Intern...[Details]
Today, under the guidance of a low-level expert, I learned how to configure the PWM module! Woof! First open the file configured last time, as follows: Then, we need to use TIM1 to set PWM: Then,...[Details]
Chip: STM32F107VCT6 Application Pin: THOUSANDS, RMII STM32CubeMX is very convenient to use ETH. The software comes with LWIP and configuration. This time, STM32F107VCT6+DP83848CVV is used. The MII a...[Details]
background After the hardware engineer completed the PCB and schematic design, the routine was modified according to the tutorial of Zhengdian Atom to verify the correctness of the hardware. STM32F...[Details]
