Hi all, I am having trouble getting my newly acquired LCD+ to talk to my 4 x 4 keypad (Jameco 169244). Connecting the right eight pins to the eight pins on the LCD+ board gives me nothing! The LCD+ doco talks of grounding to the Keypad chassis ground. Some mucking about with a bit of wire, the LCD+ ground and keypad pins revealed that those pins need to go through to ground for the LCD+ to see anything, but my keypad has no ground connection! Checking some of the Grayhill product, none of them seem to have more than the basic 8 pins either. Clearly I am missing something downright obvious (and know it), but what is it? What is the story with keypad grounding? Thanks, Andrew

Are you sure you have the connections right? The documentation for the keypad is at... http://www.jameco.com/Jameco/Products/ProdDS/169244.pdf Mine works with just the 8 connections.

Andrew, the earth is only a screen. but if your cable is longer than about 12" and has no screen, you will get unpredictable results. Some keyboards have a metal plate on the back of the keys to act as a ground plane. Tip: Use screened cable and keep the lead as short as possible. You only need 8 wires. neil Dave Houston wrote: > Are you sure you have the connections right?

Neil and Dave - thnxs - appreciate the help. Makes me feel better to know that it can be made to work with the keypad that I have! I am still most perplexed though. You guys clearly can get it to work simply by using the straight 8 wires. Me... well. Nup. I have just written the worlds simplest VB app to send it chr(25) to poll the keypad once every second(hey, don't plan to use it that way, but just want to see what it thinks is going on). I run this and it returns 255 every time (no keypad attached). I take a 10 cm wire a connect pin 1 to pin 2. Still 255. I connect any of the pins to any of the other pins - the same 255. I take the same wire, attach it to ground and touch pin 1 with it. Behold! I get 127. Pin 2 191. Pin3 223.... and so. But simply connecting pin 1 to pin (n) gives me nothing, neatly simulating my keypad experience. I am still suspecting I must be doing something terribly stupid, but for the life of me I can't figure it out. Do I have a sick LCD+?

Hey Andrew, you don't poll the keybaord Its scanned all the time, and you need to setup the keypad by sending it a ctrl-x to set its mode. I'll send you a bit of code in another email, as soon as i find it. neil wrote: > Neil and Dave - thnxs - appreciate the help.

Neil, Just wanted to publicly thank you going out of your way to help. It is folk like you that make groups like this a success. I've been tied up at work the last couple of days (and probably like the rest of us a little distracted by the horrible events up in NY). I'll bash my head against the little beast again in the next day or two and let everyone know how I get on. While I of course love showing everybody how dumb I am, if it helps someone else to read about me screwing up, it will have been worth it. :-) Regards, Andrew --- In basicx@y..., Neil Jepsen <jepsen@x> wrote: > Andrew > The code below should echo your key presses to the LCD, and > beep each key press.

Neil, Well: 1. Using your keypad settings, I was able to short the pins and get key beeps. Whatever settings I had, they were not doing the trick! 2. The key offender was my cabling. I was using some serial cabling hooked to a DB9 to plug and unplug my keypad as I pleased. This cablinghad some sort of inductive properties that while a multimeter said no resistance, they effectively shorted all the pins to each other (I was able to measure very small, significant microvoltages on all pins after connecting just one!). This was an eye opener. But my keypad is finally making my LCD+ beep and display characters. So, the moral of the story is to 1. Ask folk who know more than you 2. Be careful with what type of cabling you use! Thanks again, Andrew --- In basicx@y..., Neil Jepsen <jepsen@x> wrote: > Pleased to help Andrew.
