10 steps to selecting a microcontroller

Electronics News Updates / Ibrar Ayyub

Selecting the right microcontroller for a product can be a daunting task. Not only are there a number of technical features to consider, there are also business case issues such as cost and lead-times that can cripple a project. At the start of a project there is a great temptation to jump in and start

Reverse engineering the silicon in the ARM1 processor

Electronics News Updates / Ibrar Ayyub

How can you count bits in hardware? In this article, I reverse-engineer the circuit used by the ARM1 processor to count the number of set bits in a 16-bit field, showing how individual transistors form multiplexers, which are combined into adders, and finally form the bit counter. The ARM1 is the ancestor of the processor

Galvanic Skin Response System

Electronics News Updates / Ibrar Ayyub

Summary The Galvanic Skin Response (GSR) is a property of the skin to exhibit electrical characteristics. It is also known as Electrodermal Activity (EDA), Electrodermal Response (EDR), Electrodermal Level (EDL), Skin Conductance Activity (SCA), Skin Conductance Response (SCR), and a lot more. The GSR utilizes the principle that skin property varies with the state of

Pull-up Resistors explained

Electronics News Updates / Ibrar Ayyub

What is a Pull-up Resistor Let’s say you have an MCU with one pin configured as an input. If there is nothing connected to the pin and your program reads the state of the pin, will it be high (pulled to VCC) or low (pulled to ground)? It is difficult to tell. This phenomena is

Howto Measure RTD over long distances

Electronics News Updates / Ibrar Ayyub

1. Introduction The RTDs are the most expensive, but they also provide best accuracy and best resolution for the measurement. This, however, only if appropriate analogue circuitry will be used (which of course will add cost to the already high price of the sensor itself). The appropriate analogue circuitry constitutes the subject of this article.
