I have the following questions when learning to use 51 MCU to control LCD based on ST7920. I hope you experienced people can help me. I would like to thank you in advance. Question 1: If I want to dis...
In our common sense, the word technology often has two definitions. The first is the technology sealed in the laboratory. They are like flowers on the mountain top. Only a few people on the mountai...[Details]
1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can...[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]
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]

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]
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 role of the watchdog: Since the operation of the microcontroller is often interfered by the external electromagnetic field, the program may run away and fall into an infinite loop. The normal ope...[Details]
When STM32 uses JTMS (PA13) and JTCK (PA14) as normal I/O ports, add the following code before initialization (the order cannot be reversed): RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE); G...[Details]
