Experiment 1: Configuring the System Clock

13.4 Experiment 1: Configuring the System Clock To briefly explain the idea: using different frequencies for the system clock will result in varying execution times for a simple software delay function in the CPU, leading to different delay effects, which can be judged by the frequency of the LED blinking. The simple software delay function … Read more

PLL2 Phase-Locked Loop

13.2.2.2 PLL2 Phase-Locked Loop The PLL output is mainly used for system clock (ICLK) and others, while PLL2 is primarily used for some important peripherals, providing them with a stable clock separately. Here, we do not use PLL2. PLL2 section in the FSP clock configuration diagram: 13.2.3 System Clock Area See the marked area ③ … Read more

Opening the FSP Configuration Interface

4.4 Opening the FSP Configuration Interface If the target project is a new project, it can be compiled and run directly. However, if it is an imported project, you need to first open the FSP configuration interface to regenerate the FSP library-related code before compiling; otherwise, a compilation error will occur. The specific steps are … Read more
