During this week’s lecture, we delved into a relatively less-explored subject: USB, a widely-used protocol enabling computers to interact with peripheral devices equipped with microcontrollers. Developing a USB device empowers any computer to establish communication without the need for the specialized software and hardware that have been our focus thus far. For the next two […]

In the previous article, I discussed the USART module of the ATMega32 device, providing some practical examples. In this article, I will present additional USART examples that involve AVR C programming techniques. These techniques include creating conditions based on received characters and utilizing the ANSI C string functions library. In this straightforward illustration, the user

In this guide, we will demonstrate how to connect a 4×4 keypad, which has 16 keys, to an ATMEGA32A microcontroller. It’s essential to recognize that keypads play a crucial role as input devices in electronics projects, providing a straightforward means to issue commands or directives to electronic systems. Components Required Hardware: ATMEGA32, power supply (5v), AVR-ISP

Numerous applications necessitate an external event to prompt an interrupt in the microcontroller, enabling it to respond accordingly. For instance, an interrupt might be initiated upon the detection of a fire by sensors like a temperature or gas sensor, or when a specific count threshold is achieved. Many microcontrollers, such as the ATmega32, are furnished

The project we are presenting differs from the one initially proposed. Our original plan was to construct a WWVB time-code receiver capable of extracting highly precise time information from a 60 kHz signal provided by the National Institute of Standards and Technology (NIST). However, due to issues with a weak signal and noise interference, we
