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]

1. Function prototype In the function library officially provided by STM32, you can find functions like HAL_Delay(). This function uses a timer to achieve a more accurate time delay and provides it...[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]

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]

Security PPP is a new model of urban video surveillance projects: 1) The government and social capital establish a project company in a certain proportion; 2) The project company participates in the ...[Details]

This program uses the eight-channel ADC single acquisition mode. According to the configuration, ADC12SC will automatically reset after the conversion is completed in the single mode, so it is necess...[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]

Kevin Jensen ams Semiconductor Sensors and lighting expert. Let's learn more about the relevant content with the network communication editor. Everything is becoming "smart" these ...[Details]

With the development of the automobile industry, more and more automotive electronic components are being used in modern cars, providing better safety, comfort and economy for cars. In the past, cars...[Details]

Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]

A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]

The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]

I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]

1. Common knowledge about DMA.  1. Function: to achieve high-speed data transmission between chips. That is, it can achieve data transmission without occupying the CPU.  2. Mode: There are three tran...[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]
