AutoSAR series analysis: Mcal Mcu clock configuration
AutoSAR is an application software architecture standard for the development of automotive electronic systems in embedded systems. Among them, Mcal (Microcontroller Abstraction Layer) is a part of the AutoSAR architecture, which provides an abstraction and access interface to the underlying hardware. In this article, we will focus on the configuration of the Mcal Mcu clock and how to implement it using the corresponding source code.
Mcu clock configuration is very important in embedded systems, it determines the operating frequency of the microcontroller, the selection of clock sources and the clock distribution of each peripheral module. Properly configuring the Mcu clock has a crucial impact on system performance and power consumption. Below, we will introduce the process of Mcal Mcu clock configuration step by step.
First, we need to understand the basic principles of Mcu clock configuration. Most microcontrollers provide multiple clock sources such as internal oscillator, external crystal oscillator, etc. We need to select the appropriate clock source according to the requirements of the system and distribute it to each peripheral module. In addition, a frequency divider needs to be configured to match the clock frequency between the system clock and the peripheral modules.
Next, let's look at an example to show how to use the related functions of Mcal Mcu clock configuration to realize clock setting.
