Hello. I am tying to add some flare to my robots. I want to display some simple animations on a led matrix. I have a 4x4 led matrix and several serial to...
Its caused by tightly written loops. Sprinkle some Sleeps or Delays with zeros values through out your logic and you will reduce the occurrence of this...
Not true Dan. With serial liberal use of com3, sleeps don't help much ... ADVERTISEMENT [Click Here!] ... [Non-text portions of this message have been removed]...
I need to get a hold of some string potentiometers for a project I am working on. They are basically a pot with a pulley on it to measure the position of a...
use resistance wire my guess is 100-500 ohms/foot - depends on your geometry and what wire is available (in the old days techs would roll their own resistors...
... I've done this with a 10-turn pot. I've never heard it called a string pot. It works well for measuring short distances if the string doesn't stretch and...
I would have to disagree with Dan too. I use very tightly coded loops, tons of COM3 (and switching between 3 different COM3 ports in fast succession too) and...

Frank I have a problem at the moment as follows. I am using RS485 to poll a remote uP device ( 9600bd) and receive as reply. I poll the device by sending a 10...
You are correct Frank. I have looked at flush ser port but thought it relied on statusqueue. Will give it a whirl and let you know. Thanks neil ... ...
... I've tried it and it doesn't seem to help much. I'm using a setup very similar to Neil's except for the specific pins. (I use 15, 16 & 17.) I've tried with...
From: "Neil Jepsen" <jepsen@...> ... It does rely on StatusQueue, in part. The trouble is that StatusQueue just tells you when the queue is empty, but...
Hi folks. There are two pointers in the queue that may be useful. (See Message #8952, from 2/9/02.) One points to the first byte of valid data and the other...
From: "venture288209" <fitzmad@...> ... This may very well be true (I don't what the specific internal data structure is), but getting back to the original...
Hi Frank. You're right - it was just a thought for part of the question about knowing when the queue was empty. However, the pointers may also help with the...
okay i want to buy a lcd screen for my project. all i need is something that shows the current temperature n such like that. i also want backlighting and...
Hmmm.... I only use Delays, no sleeps, (personal preference) and I always wait for Com3 to finish its transmissions (WaitForTXC routine). I never lock up. If...
Hector, I am having the same problem with my BasicX1. It work fine with a desktop but not my laptop. Did you find a solution? I suspect the power saver in...

Frank...we put a delay in the reply so that the output Q was empty before turning it around. Works well, but not elegant. In our case speed was not an issue. ...
I would recommend the LCD+. I did the LCD device search about 3 years ago. Nothing could beat the LCD+ in my opinion. It's more then bells and whistles. The...
