We have all heard of static libraries and dynamic libraries. Static libraries are quite familiar to everyone, especially in microcontroller development. Dynamic libraries, however, are rarely seen in the microcontroller field. Today, I would like to share a method for dynamically loading functions, which is somewhat similar to dynamic libraries. Project Address: printf("hello world!"); Introduction … Read more
There are generally two methods for implementing precise delays in the 51 microcontroller: one is hardware delay, which requires the use of timers/counters. This method can improve CPU efficiency and achieve precise delays; the other is software delay, which mainly uses loops. 1 Using Timer/Counter for Precise Delay The microcontroller system typically selects an 11.0592 … Read more
Source: ICisC Nanjing Integrated Circuit Industry Service Center 1. Choosing Pull-up Resistors for Microcontrollers As can be seen in the reset circuit, when resistor R1=10k, RST is high, but when R1=50, RST is low. It is clear that R1=10k is incorrect, as the microcontroller remains in the reset state and cannot function at all. The … Read more
Search on WeChat Technical Training Can Microcontrollers Replace PLCs? Microcontrollers cannot completely replace PLCs. Although microcontrollers can achieve similar functions through programming, they are relatively less reliable and stable compared to PLCs. PLCs are widely used in industrial control and automation due to their good programmability, real-time performance, and stability. PLCs have the following advantages … Read more
In microcontroller systems, the issue of electromagnetic compatibility (EMC) is one of the most challenging to resolve. It primarily stems from electromagnetic interference (EMI) both inside and outside the system, which can easily lead to abnormal operation of the microcontroller, thereby affecting the stability and reliability of the entire system. Therefore, it is essential to … Read more
