Clock Loop,

I appreciate the advice. It will be well taken in this project. While I ended up getting reliable communications in my final experiment in that phase of my project, I realize I need to...

My test connection is only using a single 22 gauge single strand wire between the two Props and I am not using a common ground. Today I used a length of Cat 5E wire (one strand of it), that is about...

I was finally able to solve the problem, although it would be nice for someone to explain the reasoning behind what the issue was. I hooked up a serial LCD as suggested by Ravenkallen because I was...

Thanks all. I have a few things to try now.To answer a few poster inquiries, I am using Spin, I do not have any pullup or pulldown resitors in the circuit. I do have an inline resistor to protect the...

Hello,

I am very new to the Propeller, so newbie issues may be obvious here. I am trying to get a simple communication between two Propellers (a Propeller Demo Board and a PE Kit). I am using the...

Have you tried ajusting the contrast? Perhaps something you doing is actually working and you just can't see it.

That looks to be Hitachi or compatible controller, which means it should be rather straight foward to interface with the Stamp. As Franklin points, out, the 2p series having the LCDCMD and LCDOUT...

As was pointed out, you need to split up your program into "functional" blocks. Not all programs can be easily sliced up this way, but any program large enough not to fit in one slot can generally be...

Dr Evil,

You can't store those strings in a Word variable. The best you could do would be to use an array or read in each letter in DATA statements. Too much hassle. Franklin's suggestion is...

You may also be able to use an RCTIME circuit to do this.

What are you getting? Can you include the lead-in code in your program? Can you simplify the SERIN command a bit to try to get ANYTHING to parse?

You have to think about how a combination to a lock is processed. If the user stops at the incorrect number on the first pass, the lock doesn't stop the user and say "wrong first number... start...

I think you need to cycle back to Step2 in that section instead of going back to Main, which is checking button 1 again. In other words you need to cycle each button section until a button is...

Lloyd,

Neither using the SEROUT for serial LCDs or the LCDCMD/LCDOUT command for parallel LCDS are necessarily difficult, but there is a bit more to do with the parallel LCD. You will note that...

Lloyd,

Thanks for the compliment. The advantage of using Parallax Memory Stick Datalogger that you see was I could use the bike device away from a computer. I do not have a laptop. There were...

Lloyd,

I didn't mean to be confusing when I said "Manage" the back light. With serial LCDs, there is typically a command to turn on the back light. With a parallel LCD, there are two pins on the...

Lloyds,

I've played around with LCDs from several manufacturers and learned a few things along the way. Some LCD units that I've purchased on the internet did not have reliable documentation for...

This turned out to be yet one more issue with my aging PC that has been acting up lately. A new PC is already "in the mail". After a reboot, the Propeller Tool application worked and recognized the...

Hi,

I am new to the Propeller and can't get past step #1 (or is it #2?). The Propeller Tool software (v1.2.6), loads up and then goes to Not Responding after a few seconds. Two instances of the...

Senator Phil Gramm once said about gun ownership "I have as many guns as I need, but I don't have as many guns as I want." Similarly, I have as many BASIC Stamps as I need, but this is one that I...

Is your FREQOUT code working?

Adam,

Of course if you had another BS2 that would be nice to test that in the same environment. Was the BS2 in the socket when the soldering was taking place? You could try to connect the DS1620...

This is interesting. I agree that seems rather odd. In some implementations a second controller exists on the LCD (as with 4x40 LCD modules that I've used), that require you to use that other enable...

Another way to approach it would be to be cycling around with your code, monitoring the time and date from the DS1302 and comparing to a set of parameters and seeing what position the appropriate...

Kevin,

Also may want to check how your switch is connected. Are you pulling them up or down to keep the input at pin 7 from floating?
