Hello everyone,
I have created a project for configuring the peripherals of the ATSAMC21G using Atmel START (https://start.atmel.com/). I saved the configuration and exported the project. The export works also great. With the help of the *.atzip I could import the project in IAR EWARM and Microchip Studion. But before I add programs to the project I wanted to build it on a trial basis. The compiler ran well, the linker generates errors due to duplicate definitions. On closer inspection I see that the functions of the ADC have the same name as the SDADC (Sigma-Delta ADC). This is somewhat disadvantageous, since I use both ADCs.
Does anyone have similar problems? I have seen several amounts in the forum with multiple definitions. For example when using multiple SERCOMs.
Does anyone know an elegant way. Other than renaming? Because then the problem reappears with a new configuration or configuration adjustment.
I wish you a nice day and hope this thread meets interest.
Here is an excerpt of my linker(IAR EWARM):
