By Aaron Bauch, Senior Field Application Engineer, IAR Systems Design specifications require the ability to update a device’s firmware in the field dynamically. This is done commonly via a bootloader. Designing a bootloader, however, is challenging as it must meet various requirements. For example, the mechanism for getting the new application into the MPU is…
WhatsApp-based home automation: Protocol bridging with MQTT
In this article, we will be controlling devices that do not support WhatsApp but support other communication protocols like MQTT, TCP, IMAP, etc. If a house is installed with home automation devices that do not support Whatsapp, we will communicate with these devices (controllers) using protocols supported by these devices. Thus, we will be able…
ATtiny85 microcontroller tutorials, Part 3: Building LED blinking application using ATtiny85
In the previous tutorial, we learned we need the following hardware and software tools to build any application using ATtiny85. Arduino IDE software USB SPI AVR programmer PROGISP software So let us build the first LED blinking, “hello world” application for the ATtiny85 microcontroller. Open Arduino IDE. Open LED blinking example from file->example->basic->blink Modify the…
