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]

 I recently upgraded MDK to V5.25 and found that there are many libraries in the Managing Run-Time Environment. Compared with the past, it is much better, from the bottom-level driver to the upper-le...[Details]

After studying the F4 FSMC method to drive the touch screen for a few days, I have gained some understanding, which are listed below. The unorganized record is only for my own reference in the future...[Details]

Overview Lightning is a strong discharge phenomenon that occurs between thunderstorm clouds and between thunderstorm clouds and the earth due to severe convective weather. Lightning is gen...[Details]

Although it is early summer, the Chinese smartphone market is still in the cold winter, just like Beijing in April with snow. For mobile phone brands caught in the middle, the cold is even more bit...[Details]

Recently, the "Smart Photovoltaic Industry Development Action Plan (2018-2020)" jointly issued by six departments has put this concept on the forefront. Photovoltaic smart solutions will become the ne...[Details]

Since China began to try to produce panels independently in 1998, in 2018, China's panel industry has gradually upgraded from a marginal industry to the largest production scale. Especially in the ...[Details]

This example is mainly to familiarize yourself with the register configuration of Timer A and the configuration method of IAR. /***********************************************  Program function: re...[Details]

I rewrote the main part of this program. The program uses the watchdog as a normal timer and scans the digital tubes in the watchdog interrupt. In addition, I added a display buffer. If you want to d...[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]

    This paper proposes a design scheme for an embedded CNC system based on ARM and FPGA. The software and hardware design of the ARM system, the implementation method of hardware fine interpolation ...[Details]

In recent years, in order to meet the needs of social development, more and more companies have entered the fields of smart phones, artificial intelligence, VR , AR, etc. After seeing the d...[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]

STM32 has 2 watchdogs: independent watchdog and window watchdog. Independent watchdog IWDG: A system fault detector that is independent of the system and is not affected by the system because it has ...[Details]
