MCP23017 Breakout board
Jesus Echavarria has written a detailed article about his MCP23017 Brekout Board: I develop this MCP23017 Brekout Board to interface a 2×16 LCD display with any microcontroller using a standard I2C bus. Typical 2×16 displays needs at least 6 lines to work (when working in 4-byte mode); in some cases, this will be prohibited for […]
Westinghouse L2410NM LCD power supply repair
Kerry Wong fixed his LCD monitor (Westinghouse L2410NM). He documented the whole process on his blog. My seven year old 24 inch LCD monitor (Westinghouse L2410NM) started to flicker recently, so I decided to take a look inside to see what was wrong. Even before I opened it up, I had a pretty good idea of […]
Stellaris launchpad based video player
Vinod made this video player using Stellaris launchpad and wrote a post on his blog detailing it’s assembly and operation: I am introducing my new mad project, a video player using stellaris launchpad and a 320×240 color lcd which I got from seeedstudio. I tried the lcd shield by connecting on an arduino board and loaded some example […]
Tiano-MSP430 based touchscreen piano
Rohit Gupta writes in about Tiano, a Touchscreen Piano he designed using MSP430. He used a resistive touchscreen and a MSP430G2553 (although MSP430G2231 would also do). He obtained useful information in designing this project from app notes from Atmel on the touchscreen theory of operation and from TI on the touchscreen control coding.. Via the […]
Lightweight PicKit2 using USB serial LCD backpack
jeanmarc78 shared his Lightweight PicKit2 using USB serial LCD backpack in the forum: Then i decided to try to use the LCD backpack which has the same microcontroller as the basis for a lightweight PicKit2 programmer. In fact, the LCD Backpack is a quite full PIC18F2550 breakout board with a 20 MHz quartz. The standard […]
Interfacing 8 2×16 LCD displays with only two wires
Jechavarria wrote a post on his blog detailing how to interface 8 LCD displays and 24 leds with only two wires: A couple of weeks ago, I just post a review of my MCP23017 breakout board. As the board configuration allows to connect up to 8 of these boards, I decided to do it and […]
