REGISTER EDUCATION FORUM / MONOCHROME / SPARKFUN SERIAL ENABLED LCD BACKPACK SparkFun Serial Enabled LCD Backpack L C D - 0 0 2 5 8 ROHS 3 DESCRIPTION FEATURES DOCUMENTS The SparkFun Serial Enabled LCD Backpack allows you to control a parallel based LCD over a single-wire serial interface. The SerLCD backpack takes care of all the HD44780 commands allowing seamless integration with any micro that can communicate over a wide range of TTL serial baud rates. The SerLCD currently supports 16 and 20 character wide screens with 2 or 4 lines of display. Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps (8-N-1). You can adjust the baud to any standard rate between 2400 and 38400bps. The power, ground and RX pins are all broken out to a 3.5mm pitch screw terminal. SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the backpack to adjust the contrast. Note: The SerLCD v2.5 Datasheet incorrectly identifies the PIC as a 16F688, when it's actually a 16LF88.

It might be a couple simple solder joints, or require special reflow tools. Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need. See all skill levels 1 Core Skill: DIY Whether it's for assembling a kit, hacking an enclosure, or creating your own parts the DIY skill is all about knowing how to use tools and the techniques associated with them. Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns. See all skill levels 1 Core Skill: Programming If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code. Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginnerlevel software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL. See all skill levels 2 Core Skill: Electrical Prototyping If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics. Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

I had a lot of trouble finding and installing the files to make it work. working with files in the Arduino IDE. is hard for me to understand. unzipping and putting files into folders and then having to rename them and move them around is above my ability. Spark fun products are good I have used your products in the past and will continue to buy from Spark Fun. It would be nice for people like me, if you offer software, to make it auto install and no errors!!! and also a good schematic would be nice. Keep up the good work. Works Great! about 3 years ago by Member #635840 verified purchaser I had this up and working very quickly. I only gave it 4 stars because: There is discrepancy on the interwebs on whether it requires 5v or 3.3. Since I used this with an electric imp I had to pull in a 5v power source. Documentation seemed lacking on the pinouts to connect this to the LCD. I'm curious if you can send special characters to the LCD through this board. I didn't see anything in the documentation on that either... All in all, provides basic control of an LCD with 1 wire. Good product about 8 months ago by Member #588774 verified purchaser Easy to assemble START SOMETHING.
