Shenzhen Huichun Technology Co., Ltd. was established in December 2007. It focuses on chip design for consumer electronic products and is one of the leading integrated circuit chip design companies in China.
Now we need to use the FSMC bus to communicate between F4 (transmit) and F7 (receive). We hope to write directly into the SRAM of F7, but we don't know the SRAM address of F7. How should we operate th...
I have a power management chip, the silk screen on it is DE=NOT, the package is SOT23-5, please help me take a look, thank you[/size][/font][/color]...
I'm a newbie and just started learning Verilog. I'm working on a SPI receiving module. I encountered a problem during the testing phase. I don't know how to use simulation to verify the received signa...
As the title states, 5G requires a lot of infrastructure, and the United States is vast and sparsely populated. Is it possible to directly use satellites to lay out 6G?1. What are the differences betw...
I am using STM32F407ZG. This is a program that reads buttons. Every time the program runs to this point, it will enter the if statement regardless of whether the if condition is equal or not. I have n...
STM8SPWM Application A few days ago, there was a project that used PWM. Today, I sorted it out and made an atmosphere light. I recorded it so that I can come back and look at it later if I forget i...[Details]
This program measures the PWM high level time and cycle through two timers and one external interrupt, calculates and displays the duty cycle high level time in 1602. The data can be measured by simp...[Details]
