[size=4]Number calibration[/size] [size=4] In fixed-point DSP chips, fixed-point numbers are used for numerical calculations, and their operands are generally represented by integers. The maximum repr...
A few days ago, I adjusted the driver and was able to read the six-axis data correctly. Now I want to read the hardware pedometer data and find that the data I read is 0. I simulated it but it didn't ...
How to judge whether the selected CPU and memory are compatible during circuit design? Does the matching of pins mean that the memory and CPU are compatible?...
I bought an STM8S-discovery some time ago, and recently there was a problem when burning the program. The RST pin of the STM32 was always low, which resulted in the program not being able to be downlo...
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]
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]
Recently, Zhejiang Lipu Crushing Equipment Co., Ltd. invested 50 million yuan to build a new "annual production of 1,200 high-efficiency and energy-saving ultra-fine pulverizer construction project...[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 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]

In one of my products, there are two chips, AVR and PIC, at the same time. When AVR drives the relay, then drives the contactor. PIC is used for display. I found that PIC actually has a little interf...[Details]
Pay attention to whether the new lock matches the old door Smart locks have many advantages over traditional mechanical locks. Although the domestic penetration rate is not high, with the strength...[Details]
The top row of pins is the row, and the bottom row of pins is the column. The row is the LED anode. Each row and column is controlled by four 74HC573, each controlling 8 pins. At the sa...[Details]
