LCD Interfacing with AVR

Interfacing LCD Display in 8bit Mode I’ve already discussed about the LCD display in a note here in this website. You can read the Note on character LCD Display here. Now let us come to the interfacing side of LCD. Let us see the 8bit mode interfacing of the LCD display with an AVR micro controller first. I have added two circuits in this post 1) Interfacing LCD with Avr Atmega8 and 2) Interfacing with Atme ...

Week 11: Networking with ESP8266

For this week I set out to make a board that will show realtime MBTA bus arrival times using the ESP8266 wifi module and a LCD. Seemed doable. People of the internet have been excited about the ESP8266 lately. Here is a snapshot of google trends for searches for esp8266 vs couple of other arduino favorite processors. That's the rough plan. I run the atmega32u4 and the LCD at 5V. The ESP8266 I power at 3.3V ...

Running an HD44780 Display off the ATmega on a Gertboard

There was a thread on the Raspberry Pi forums about running a 16x2 HD44780 based display off the ATmega chip on the Gertboard.  I normally use a shift register to run my display, so I wasn't much help to them.  I decided to try and get it setup without the shift register to help out the folks having trouble. So, this instructable will detail how to go about getting an HD44780 display running off the ATmega ...

Interfacing 16X2 LCD to AVR Microcontroller

  Well this is not different from the way interfacing the LCD to 8051 or PIC microcontroller. The crystal oscillator will provide the clock to the microcontroller. The capacitors connected to the crystal will act as filters and help the crystal to resonate and oscillates to its parallel resonate mode.  The potentiometer which is connected to the pin 3 and pin2 of LCD will help to adjust the contrast of the ...

LCD interface

This example is based on a LCD module with the Hitachi HD44780 LCD-controller.You can get these displays in various kinds, from 1 to 4 lines and from 8 to 40 characters per line. A display with 16 characters per line and 2 lines is used in this example. The display uses a power supply of 5V DC. The LCD controller can accept 8 bit data bytes or 4 bit nibbles. In this example the 4-bit mode is used. There are ...

LCD/switch interface

Page 1 of 2 This board can directly connected to the STK 500 board or the ATTiny2313 ISP program board with a 10 pole flatcable on the 10 pin header of the STK500 and the 10 pin header of the LCD/Switch board. The display has 16*2 character positions and is Hitachi HD44780 compatible, and also has a LED backlight that can be switched on/off by a jumper. You can puchase the ATTiny2313 board at www.bizztronix ...
