3 Driver Implementation

The example code is written for Atmel START. It can be downloaded from the "BROWSE EXAMPLES" entry of Atmel START for both Atmel Studio 7 and IAR™ IDE. Double click the downloaded .atzip file and project will be imported to Atmel Studio 7.

To import the project in IAR, refer "Atmel START in IAR" , select Atmel Start Output in External Tools -> IAR.

Note: This external interrupt driver is not intended for use with high-performance code. It is designed as a library to get started with the external interrupts.
The example codes included are:
  • Basic external interrupt usage on ATtiny88
  • Nested external interrupt usage on ATtiny88
  • Generating software interrupt with external interrupt pin configured as output in ATtiny88
  • External interrupt for device wake-up of ATtiny88
