LCD circuits often require a –10V voltage at 2 to 15 mA to bias a graphics-LCD-driver IC. You can usually accomplish this task with an external charge-pump IC, such as Maxim’s ICL7660, but that ...

This project completely deals with the interfacing AVR microcontroller (ATMEGA 16) with 16X2 LCD. The Atmega16 belongs to the AVR microcontroller family. This project completely deals with the ...

Until recently, a very common problem faced by electronic circuit designers was the difference in supply voltage standards between microcontrollers (e.g. 3.3 V) and peripheral ICs (e.g. 5 V). In order ...

When it comes to displays, there is a gap between a traditional microcontroller and a Linux system-on-a-chip (SoC). The SoC that lives in a smartphone will always have enough RAM for a framebuffer and ...

Atmel has announced the integration of an lcd controller into its AVR XMEGA microcontroller range, which it claims reduces design complexity and lowers overall system cost. The integration, adds the ...

Microchip Technology Inc. announces an expansion of its 8-bit segmented LCD microcontroller (MCU) family with five new devices — the PIC16LF1902/3/4/6/7 (PIC16LF190X) MCUs. Microchip Technology Inc.

A rduino boards are a popular choice for DIY electronics, but it's not always clear how to get started with building projects ...

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

While [Vinod] says he’s not an expert in this sort of thing, we really like his audio spectrum analyzer build from a simple microcontroller and LCD display. It is a well-studied fact that every audio ...
