This repository is a training module covering basics of GPIO, TCA, TCB, events, USART, CCL and PIT to create simple applications for the ATtinyAVR 1-series.

Getting Started with the tinyAVR® 1-series

This repository contains training examples on the Microchip tinyAVR® 1-series. Follow the Training Manual - Getting Started with the tinyAVR® 1-series from Microchip for full step-by-step description. The training is carried out on a ATtiny817 Xplained Pro board.

This training includes three assignments covering topics such as:

• Driver Configuration in Atmel START
• PINMUX driver configuration and check LED toggle on button press
• Generate a PWM by using timer counter A (TCA) and implement Variable-Pulse-Width by using the RTC interrupt
• Duty cycle and frequency measurement using input capture mode of TCB
• USART configuration
• CCL (Configurable Custom Logic): A programmable logic peripheral, which can be connected to the device pins, events, or peripherals, which allows the user to eliminate external logic gates for simple glue logic functions.

The code in this repository is configured for the last assignment. Refer to the Training Manual - Getting Started with the tinyAVR® 1-series for additional information on how to configure from scratch.

This training manual is based on using Atmel Start with Atmel Studio. It can, with some adjustments, be used with MPLAB X IDE. When the traning manual re-configures the project using Atmel Studio: go back to the Atmel Start website where the project was created and exported to MPLAB X IDE. Re-configure the original project before exporting it to MPLAB X IDE again. You can now copy and move all the new files, except main.c, over in your old project folder. In this way changes you have made in main.c are kept, but the system is re-configured.
