I am trying to use the I2C CMSIS driver for the Cortex M0+ processor (KL25Z128) with Keil uvision IDE.From the "Manage Run-Time Environment" window, I added the following:
This added to my project the header file "Driver_I2C.h", which I can use to call the functions that interact with the I2C.However, please correct me if I'm wrong; the header file functions have no implementation. I have to create a new file from the template, which will generate empty functions. I should then fill them out.
My question is: what is the purpose of the CMSIS I2C driver if it doesn't offer any implementation of the functions and if I have to implement it myself?
I might be missing something here, but I'm really struggling to understand where the implementation resides.
Any clarification would be much appreciated.
Alright. Thanks for the explanation. I understand now.
