YARM development using "Atmel Studio 7" and "AFS" Library.
To use this libraries follow this simple guide line.
- You must download and install Atmel Studio 7 from here: http://www.atmel.com/Microsite/atmel-studio/
- Launch "Atmel Studio 7" then select "File -> New -> Project". Inside the "New Project" window click on and select "GCC C ASF Board Project"
- Type in the name of your project, and click "OK".
- A new windows appear. Now you must choose the MCU. Select inside "Device Family" pop-up the family "SAML21"; then select the "ATSAML21E18B" device and click OK.
- The new project will be created. Now is time to insert the "Atmel Software Framework (ASF)" modules.
- Select "Project -> ASF Wizard" from the menu, after a while, on the left side of the window will appear a list of the available modules.
With the help of the "Search for modules" text box, search and then "Add >>" the following modules:
- Generic board support (driver)
- Delay routines (service) [cycle] ^1
- EXTINT - External Interrupt (driver) [callback]
- PORT - GPIO Pin Control (driver)
- RTC - Real Time Counter Driver (driver) [count_callback]
- SERCOM I2C - Master Mode I2C (driver) [polled]
- SERCOM SPI - Serial Peripheral Interface (driver) [callback]
- SERCOM USART - Serial Communication (driver) [polled]
- SYSTEMS - Core Systems Driver (driver)
- Standard serial I/O (stdio) (driver)
- N.B. Some of this modules can be configured using a pop-up menu on the right of the name. The correct value to set is inside the square bracket of each modules.
- Click on "Apply". At this point your project is ready to use this libraries.
- Inside the project window, right click on the "src" folder inside the "Solution Explorer" window on the right. Choose "Add -> Existing Item" to copy the source library inside your project.
- Remenber to add inside in "Properties -> Toolchain -> ARM/GNU Linker -> Miscellaneous" the option: "-lc -u _printf_float" to visualize the float value with "printf".
^1 On Atmel Studio 7.0.634 and ASF 3.31.0 set the Delay routines (service) [systick]
