Osepp lcd keypad shield

Pages: [1] 2. Alright I wasn't sure where to put this, I am not really having issues with the shield, aside from "what to do with it" my concern is the "with" since I drop it on top of the micro controller, and no more pins available. I suppose I could attach to a bread board, and then go from there?

This is what I got.

It is currently a clock LOL. I had to do something with it. I guess what I am asking also is how do I get more use out of the Arduino, while this shield is plugged in. Re: lcd 16x2 shield. You might want to find a plastic case for the shield but once you connect the pins used by the lcd LiquidCrystal lcd 8, 9, 4, 5, 6, 7 to the shield and the one analog pin it needs then it will not know it is not plugged into the arduino and you can use the arduino as you wish.

If you need help setting up the I2C adaptor let us knowwe've already been through that drill with someone else and have all the relevant config info now. Danger, Will Robinson! What you "do" with the shield, is to purchase a set of "extender" headers for the Arduino so that you can mount the display shield over the sensor shield once you have whatever sensors you require, plugged in.

There is of course, a problem that the LCD shield will use pins that would otherwise be available on the sensor shield, but you would have to allocate them anyway.

Pleas note however that this shield does have the "bodgie" wiring blunder described in the "sticky" at the top of this forum and needs to be modified unless you are extremely careful with coding especially for it as it can damage the Arduino.

Thanks for the reply's guys. I appreciate it. Paul, thank you very much for the link, and the warning. I would have never figured this out, without destroying something LOL. I downloaded the LCDcheck on the forum link, yes sir, bad pin So Well I guess I can use this to play with and test, and just avoid pin 10, germanium 1n34a solution, or, which I think is the proper answer, get one that works properly.

So that being said, any recommendations for an lcd screen. I was also looking at a touch screen as well, which I would really like, but this little experience has made me a little nervous about purchasing. I want to buy a touch screen anyways, so perhaps that is the route to go.

I Contacted Osepp via email yesterdaywith the specifics and the link, as I thought they should know this. My intent was just to inform them about the issue, so they can at least warn people about it. They returned an email and asked for my address to get me a new one, without the 10 pin issue, ASAP.

I must say I am surprised and impressed that they want to send me a new one. Go Osepp. Quote from: sensai on Feb 09,pm. Quote from: bperrybap on Feb 10,am. Quote from: sensai on Feb 10,pm.Work fast with our official CLI. Learn more.

LCDKeypad shield is quite common and popular. Pins 4, 5, 6, 7, 8, 9 are used to interface with the LCD. Analog pin 0 is used to read the buttons. You can optionaly specify button analog pin default A0 and backlight pin default Lcd pins are 8, 9, 4, 5, 6, 7.

All the defaults pins can be changed by editing appropriate defines. You can also change button analog level values if default ones do not match your board. Read filtered button states. Great for use in menus or similar situations where you need only one button press code.

Thank you Clay, I'm not using any library. I figure it out a few days ago, this shield is a mess mapping its signals to physical pins. So I took a multimeter and start finding the signals. Here are my findings, hope this help. If you have a previously loaded Sketch on the Galileo, that might cause an issue.

Wiring the LCD 16×2 Keypad Shield on Arduino

I bread boarded the shield before connecting myself. I have unloaded the sketch, taken the shield off and back on. Nothing works on the galileo. Anyone know of pin incompatibilities on the Galileo boards that don't truely match the Arduino Uno specification? Now, after installing on regular UNO board, it powers up on the Intel board. Very strange. More updates on Monday, after I fix the library code. On your installation dir, locate the file LiquidCrystal. This is going to be integrated soon in the official IDE release but use this file as workaround.

Judging from the date, it should have been for Gen 1 Galileo since the Gen 2 was not yet released back then. Is the replacement LiquidCrystal. My Gen 2 boards work well with the as-is LiquidCrystal library files, I wonder if this fix for Gen 1 will still keep the Gen 2 working.

I was planning to use this sort of LCD shield for my next char 16x2 or GLCD project however not with a keypad one but this post surely warns me to look out for this abnormality.

Thank you! For those wanting to test their shield for this problem, there is an easy test. It is no longer recommend. Use the test sketch, or the hd library and its test sketch to test for the issue.

Refer back to the original post for details.

OSEPP LCD and keypad shield

Remove the shield from the arduino. Attach a wire to the D10 pin on the shield. Hook up ground and 5v to the corresponding shield pins. When power is turned on, the backlight should light. Ground the wire going to D10, the backlight should go off. Now for a simple test. Briefly and I mean just a brief touch connect the wire from D10 to Vcc. If the backlight, blinks when you touch the D10 wire to VCC, the shield has this issue. You can still control the backlight.They provide an adjustable backlit LCD display with two lines of 16 characters, six programmable pushbutton switches, and a reset switch.

They're available at reasonable cost and look to be a good solution for adding a minimal user interface to a prototype or lab project. Unfortunately there are a few problems with these that will tax your sanity and possibly fry your Arduino.

Hopefully my experience with it will save you some time and trouble. Several online vendors sell boards that appear to be identical to this one so this information ought to apply to them as well, but the OSEPP one is the only one I've had direct experience with.

This and similar boards allow the LCD backlight to be switched on and off by toggling the state of the D10 digital output pin. When D10 goes high, the backlight is switched off.

Unfortunately, there's a design fault that will eventually fry your Arduino if the backlight is switched off. At least one online vendor specifically warns users not to play with D Several solutions to this issue have been devised but the only one that's likely to be feasible and infallible, especially in an educational setting, is to disable the backlight control altogether by cutting off the D10 pin on the bottom of the display board.

This will make the backlight stay on all the time. You'll need a pair of fine wire cutters for this. When in doubt, take it to your IT person. If you don't do this, my bet is you're going to have an epidemic of blown microcontrollers. Here is very informative forum thread that outlines the problem in detail. If you're going to be doing more with this than printing messages on the LCD, you're going to need access to the Arduino interface pins that aren't used by the display.

Three of the four sets of interface pins on the display board have a parallel row of holes, but no connectors. I've heard of people just sticking jumper wires into those holes but that didn't seem like a particularly robust solution to me. After a few experiments, I opted to use a set of stackable headers.

It was necessary to shorten a couple of these by removing pins from them. I put the connectors in a vise and carefully cut off the required number of pins with a cutoff wheel in a Dremel tool. Rather than having the new header connecters mounted at right angles to the board, which would have interfered with mounting it in an enclosure, so I clamped the pins of each connector in a vise and carefully bent them to a degree angle.

Finally, I soldered the connectors in place from the back side of the board and cut the pins off flush with the back of the board.

That is to say, I cut the newly-installed pins, not the ones that were already there. You need those. After using this for a while, I'm not sure I'd do it this way again. Having the jumper wires for the power and digital pins connect on the sides of the device is awkward and if all you're not putting the display in an enclosure, not really necessary.

Next time I mod one of these boards I might just install the headers perpendicular to the circuit board without bending the pins. The pinouts of the two connectors on the "bottom" edge of the board are incompletely but usefully labelled and in any case follow are in the same order as the pins they connect to on the Arduino.

It is also unlabelled and I guarantee you will never be able to figure out the pinout from the wretched excuse for a schematic diagram provided by the vendor. The pinout of the top connector, from left to right when looking at the board from the front, is as follows:. While we're on the subject, note that D1 and D0 are also used for serial communication and can't be used if your program uses serial communication. Also, I found that if there was anything connected to D1 or D0, it had to be unplugged before uploading a sketch that is, a program to the Arduino.

Here's a simple project using the LED Keypad Shield and an ultrasonic range sensor: a distance-measuring device. Disabling backlight control.

It does not look like you hooked up Vo to the variable resistor in the schematic. Can you confirm you hooked that up? Does the contrast on the display change when you change that variable resistor? Thanks for input bko however, I believe it is hooked up. This schematic is for hooking up to the LCD directly the blue board, not the black board in your picture.

Here is my stab at a map for you using this shield… the J? I had to use that schematic. I saw it when I first stared working on this this morning and had absolutely no idea how to relate, I spoke with some friends and they helped me understand better.

The end result is that the following image shows numbers in pink that correspond to the LCD please ignore my D pinsI also used pwm pins according to the diagram did I need to use pwm pins?

An issue I had was to kind of guess what J7 and J6 were from the diagram, how come it is not labeled on the shield board or is it?
