Launched in 1996, the AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two ...

Regardless of whether you love it or hate microcontroller documentation, you still have to negotiate it. In the first part of this article series, we looked at what is found in a microcontroller ...

In the previous parts of this series, we covered register functionality and took a look at the clock block diagram. Here we provide more block diagrams and investigate where you can find the rest of ...

ATmega16 is an 8-bit high performance microcontroller from the Atmel’s Mega AVR family. Atmega16 is a 40 pin microcontroller based on enhanced RISC (Reduced Instruction Set Computing) architecture ...

Many of us should be familiar with the popular microcontrollers and development boards like Arduino, Raspberry Pi, ESP8266, NoduMCU, 8051, etc. In fact, for most people, Arduino would have been their ...

Here’s an interesting article about reading data from shift registers using less than three pins. 74HC165 shift registers are a popular choice for adding inputs to a microcontroller. They have a ...

Digital and Analog is an integral part of Electronics. Most of the devices have both ADC as well as DAC and they are used when there is a need of converting signals either from analog to digital or ...

In most keypads, pressing a key closes a contact that bridges two lines in an xy matrix. If you use a microcontroller to detect a key closure, checking the states of (x+y) lines requires an equal ...
