The solution requires two serial ports: ● Receive and process the serial port data of device A, and then send it to device B; ● Receive and process the serial port data of device B, and then send it t...
I started using the MSP430 series for experiments when I was in school. I have made many small things and have a clearer understanding of microcontrollers. Now TI has upgraded the MSP430 series produc...
The current status of the serial port driver in the powerpc+linux environment is that the console works well, but another serial port (used for data transmission) reports the following error (open err...
I want to learn embedded Linux recently, and I want to buy a microcontroller to get familiar with the use of embedded Linux. I don't know which board is better? I searched on Baidu and found that TQ24...
The most significant event in the technology circle during this period is undoubtedly the news that ZTE was banned by the United States. Once the news came out, it shocked the entire Chinese techno...[Details]
Designing for automotive LCD displays larger than 5" can be complex. The display source driver requires a supply rail called analog voltage device drain (AVDD) in the 10V to 15V range and two supply ...[Details]

The independent watchdog of STM32 is driven by a dedicated internal 40Khz low-speed clock, that is, it is still effective even if the main clock fails. Here we need to note that the clock of the inde...[Details]
At this exhibition, Microsoft brought its flagship intelligent voice products - XiaoIce and Xiaona. In addition, the voice will be equipped with an intelligent face recognition system. Let's see ho...[Details]
1. Function and purpose There are two pins BOOT0 and BOOT1 on each STM32 chip. The level status of these two pins when the chip is reset determines which area the program starts from after th...[Details]
1. What is PWM What is PWM? Professionally speaking, it is pulse width modulation. In layman's terms, it is the continuous output of high and low levels. For example, the microcontroller outputs...[Details]
Timer Interrupt The timer function of STM32 is very powerful. There are advanced timers such as TIME1 and TIME8, general timers such as TIME2~TIME5, and basic timers such as TIME6 and TIME7. In th...[Details]
For complex calculations, the speed of the microcontroller is too slow. The best way is to manually calculate all the results in advance, store them in ROM in sequence, and then directly check the re...[Details]
