A Method for Dynamically Loading Functions in MCU

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

Accurate Delay Methods for 51 Microcontroller

by
Accurate Delay Methods for 51 Microcontroller

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
