Rotary encoders are pretty interesting pieces of technology. They’re a solid way to accurately measure rotation including the direction. [David] recently wrote some software to handle these input ...

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.

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 ...

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

Atmel has introduced a 6-pin microcontroller. The 8bit AVR ATtiny10 has 1kbyte of flash and 32byte of SRAM in a 2x3mm SOT-23 package. Performance is claimed to be up to 12MIPS, and peripherals include ...

Embedded code development software does not come cheap if you are developing tens of thousands of lines of code in a multi-engineer project. On the other hand, if the project is smaller, and ...

Microchip Technology expands its Arm Cortex‑M0+ microcontroller offering with the launch of the PIC32CM PL10 family.

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 ...
