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]

When Amazon launched its first cloud computing service, the outside world was not optimistic about this direction, as it had high investment, low profits and many uncertainties. Let's follo...[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]

What is SYSTICK: This is a 24-bit system tick timer, SysTick, with automatic reload and overflow interrupt functions. All microcontrollers based on the Cortex_M3 processor can obtain a certain time ...[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]

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 Vatican Secret Archives is one of the world's greatest historical collections, but many of its documents have never been transcribed. Recently, a project called Codice Ratio used a combination...[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]

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]

Homemade LED Electronics   Clocks can be seen in many electronic newspapers and magazines, but most of them need to reset the time and other parameters after power failure, which brings a lot of inco...[Details]
