1. Principle 1. Infrared emission protocol There are many infrared communication protocols. This experiment uses the NEC protocol. This protocol uses PWM modulation and uses pulse width to represen...[Details]
Today, under the guidance of a low-level expert, I learned how to configure the PWM module! Woof! First open the file configured last time, as follows: Then, we need to use TIM1 to set PWM: Then,...[Details]
introduction STM32 has many registers, which are difficult to remember, so the official packaged two sets of library functions. One is the standard library, but the official has not updated it on F7,...[Details]
I have always wanted to write some posts and blogs, but I just couldn't bear to do it as I just graduated. After some preparation, I decided to write down some of the things I learned in the past few...[Details]
Serial Port: 一. USART_ITConfig(USART1, USART_IT_TXE, ENABLE): As long as the transmit register is empty, there will always be an interrupt. Therefore, if you are not sending data, turn off the tran...[Details]
Time flies. Since the beginning of 2018, news related to home appliance companies have repeatedly made headlines, and competition in the home appliance market continues to intensify. In order to be...[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]
Superconductors have physical properties such as zero resistance effect, Meissner effect and Josephson effect, which make them have broad application prospects and unparalleled advantages in many b...[Details]
This small program is still the use of timer, which is relatively simple. The specific parts are noted in the comments, please refer to the comments. /*********************************************...[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]
This routine is also a classic routine on the development board. I modified the framework of the program to make it more suitable for future calls. The specific 4*4 keyboard scanning principle is rel...[Details]
