MCAL API Descrption

Embedded_novice — Wed, 25 Jun 2025 02:24:09 GMT

Currently, in the MCAL static code, I can only understand the usage of the API through the function comments. I would like to know if there are any documentation or websites available to query the explanations and parameter descriptions of each API in the MCAL API functions?

Hello,

API documentation is present directly at plugins:

For example ADC:

There is doc folder where you can find implementation and user manual.

best regards,

Peter

However, this seems to only include the outermost encapsulation interface. I was able to find the function Mcu_GetPllStatus, but the deeper-level function implementations within it, such as Mcu_Ipw_GetPllStatus, cannot be found in the manual. Can I understand it as follows: The manual only presents the API of the outermost layer, while the internal implementation API can only be understood through the comments?

Hello,

You are right. I do not see them in the API documentation.

Therefore I expect it could part of general AUTOSAR specification.

But I have only ASR 4.0 documentation here and I did not find it there.

As you shared, you can understand it from the code c and h files. Seems to me the quickest way to see the parameters.

Best regards,

Peter
