Developing IoT Devices Using AVR Microcontrollers
The lecture series will begin by defining the architecture of an AVR microcontroller. The knowledge gained from our study of the AVR innards will be put to use in an 802.15.4-based IoT application.
ToDay's lecture is all about gathering data, storing it, displaying it or moving it about using AVR microcontrollers. The focus will be on developing low-level AVR drivers that are capable of interfacing an AVR microcontroller to various types of sensors.
MikroElektronika offers some very nice AVR development hardware. Coupled with Atmel Start, Atmel Studio 7 and an Atmel-ICE, the MikroElektronika XMEGA hardware development systems are compact enough and powerful enough to allow you to craft IoT designs at your desk. We will use the aforementioned development tools to bring some IoT ideas to life.
The ATmega4809 Xplained Pro development board is designed to interface with MikroElektronika click boards. In this lecture, we are going to 'click” on everything AVR and explore interfacing various MikroElektronika click boards to a number of differing AVR microcontrollers.
The final lecture in this series will utilize the services of a DIGI XBEE Cellular LTE CAT 1 Development Kit to demonstrate how AVR microcontrollers can be used in the realization of cellular-based IoT devices.
