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]

For STM32, there are two ways to reset the software:   1) Use the official software library     The system reset function is directly provided in the stm32f10x_nvic.c file of the official software li...[Details]

The status of interrupts in developing embedded systems is absolutely unquestionable. In the era of C51 microcontrollers, there were only 5 interrupts, including 2 external interrupts, 2 timer/counte...[Details]

In the actual project development process, it is common to encounter modifications to the hardware circuit, and then the modified part requires the modification of the driver. Thinking about the comi...[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]

1. Initial understanding of FSMC: FSMC consists of 4 modules: (1) AHB interface (including FSMC configuration register) (2) NOR flash memory and PSRAM controller (when driving LCD, LCD is like a PSRA...[Details]

Superconductors have physical properties such as zero resistance effect, Meissner effect and Josephson effect, which make them have broad application prospects and unparalleled advantages in many b...[Details]

Autonomous driving and 5G are the two hot topics that global companies and media are paying the most attention to, and the combination of the two is the focus of everyone's attention....[Details]

From the functional classification, it can be divided into: 1. Active control ADAS: ACC/AEB/LKS, etc. 2. Warning ADAS: FCW/LDW/PCW, etc. 3. Other auxiliary ADAS: BSD/ADB/panora...[Details]

This is a "cooperation" that is related to the future development of China's semiconductor industry. Let's follow the embedded editor to learn more about the relevant content. Last week, a...[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]
