In the 3G era, can it replace the original fixed broadband? In January 2009, China issued three 3G licenses. Telecom cdma2000 launched the Tianyi brand, claiming that the test speed has reached 3.3Mbp...
Can be used on wince to do pushmail. A friend said he had heard of it and asked me, I don't know either, so I'm here to ask everyone if the word may be spelled wrong. Thanks!...

1. The first project We are going to create the first project, which is mainly for project analysis, so that we can understand how CubeMX works and how to trace the code logic. Okay, no more nonsense...[Details]
This is my first time writing an STM32 program. I have many questions to ask. I want to convert the data of the SO of MAX6675 into the actual temperature and read it out using the serial port tool. I...[Details]

I used the bit definition in my 51 program: bit flag. After defining it this way, I ran the program and downloaded it to the circuit board. I found that the flag was not the value I set, which led to...[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]
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]
The clock system of STM32 can be directly summarized in a diagram (from the STM32F10X reference manual). The following is an analysis of this diagram 1. STM32 input clock source 1.1 Function of cl...[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]
How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
Interrupts and timers implement a 24-hour clock. The program is as follows: #include reg52.h #define PORTLEN P0 sbit bit_select = P2^0; sbit seg_select = P2^1; unsigned char src = {0x3f,0x06,0...[Details]
Each I/O port of the AVR microcontroller corresponds to three registers: DDRx, PORTx and PINx, where DDRx is the data direction, i.e. input or output; PORTx is the state of the internal pull-up r...[Details]
