Many of today’s designs use low-cost microcontrollers from Freescale and Microchip, but during the last decade, device packages have resorted to ever-smaller footprints featuring as few as eight or ...

Part of setting up a microcontroller when writing a piece of firmware usually involves configuring its connections to the outside world. You define a mapping of physical pins to intenral peripherals ...

There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

Inputting multiple bits of information using a single entry pin of a microcontroller without the complexity of UARTs can prove useful. Such a scheme could allow scanning of a keyboard, mode switches, ...

Eight-pin microcontrollers offer numerous peripheral features. However, the maximum number of I/O pins available is often limited to six, since two pins would be required for the chip's power supply.

Lots of programs take data from a file and create an X-Y graph under Linux. Desktop applications like xplot, gnuplot or even PHPlot do a great job. But, what if you want to see how a physical process ...

A microprocessor is an integrated circuit that contains no memory. A microcontroller has the ability to store information. The size of a circuit can be significantly reduced. This is because ...
