We have developed a complete guide to learn AVR microcontroller – a tutorial which teaches the architecture,pin diagram,how to program an avr micro controller, how to work with ADC of avr, how to work with SPI of avr,interfacing LCD... read moreHow to work with the ADC unit of an AVR Micro-controller
Introduction The first step to digital signal processing is to convert a signal into digital data, and here the Analog to Digital Converter devices comes into action. Some of the AVR micro controllers include ADC unit in their... read moreWorking with External Interrupts in AVR micro controller
Introduction to Interrupts Although micro controllers can accept inputs from Digital I/O Ports,interrupts are preferred for accepting inputs generated by external events. This is mainly because of the less attention required for an interrupt based program. An Interrupt... read moreHow to Establish A PC-Micro controller USART communication
Introduction USART is one of the primitive inter-device communication protocols. It is not used in modern computers. But still, a few mother boards come with the module necessary for an USART communication. Here, in the case of PCs, the... read moreHow to Work With SPI in AVR Micro Controllers
Introduction Micro controllers support wired communication protocols. Most of the time, microcontrollers come along with internal modules that support these protocols. The commonly supported protocols are: UART or USART communication SPI TWI USI etc. And few advanced protocols... read moreHow to Work With 32K crystal and AVR Microcontroller
