I have to develop a project with the ATSAMD20E14 which involves:
- Configure Internall Oscillator as the main clock source for the process. (I'm planning to use the 8MHz internall oscillator from the SAMD20E14)
- Configure External Interrupt (Rising Edge could work)
- Configure I2C module with SERCOM according with the Datasheet
- Configure 2 timers:
- 8 bit timer
- 16 bit timer
- Configure DAC module
- Configure GPIO pins.
The problem is that I'm familiar with the Microchip 8bit Microcontrollers and I don't have too much experience with AVR MCUs (I have developed some small projects with ATMEGA164A). So I was wondering if you know some resources or a good way to start getting familiar with the SAMD20E14 MCU.
I was thinking to start with the 8MHz configuration clock and then go with toggling a LED using GPIOs, delays, and next I will go with the rest of all the peripherals that I have to deal with.
Do you know some tutorials to follow or the only way to go with this is through ASF examples? It is a little bit hard to follow the ASF examples as they are not too much descriptive.
Also the other things is that I don't have the hardware in my hands so I will follow my codes through Simulator debugger from Atmel Studio 7.
Thanks, and I will look forward to read some good advices from you guys.
