My project is to control the temperature of a plant. The temperature of the plant will be monitored and as an input of the basicX controller. If the input...
I’m sure there are more sophisticated ways to do this, but… In theory you’re supposed to be able to put a very low resistance very high wattage resistor,...
After reading about Com3 overhead on one of the boards, I decided to measure it to determine if opening Com3 only when needed would be beneficial for my...
After about 2 or 3 thousand hours of use, I'm finding that the BX24p internal pull-ups are going bad. So far, 3 of them have gone south. The circuit is only a...

My experience is the contrary. I've never seen a bad pullup on a BX-24 pin; I've smoked a few pins, but only in careless development by my own hand. ... How...
I'll have to agree with Tom on this one, the internal pullups are internal to the Atmel chip, not the BX24 board. Thinking aloud: Given that I have a few spare...
Hi everyone, thanks for the help so far. I've done the recommended reading on the web and found a controller which I think is able to solve my problem. ...
... tempature ... Depending upon the required accuracy, you may or may not need PID control. Will your control device be simple heat on/off, cool on/off or do...
... If you understood my previous post then setting your control values should be done in stages. NOTE: I would use "Single" data types for the Gains as you...

... According to Netmedia, it's "For Windows 95/98/ME/NT/2000/XP" so you should be able to run a 386/16 with Win95 - or anything Wintel, later and faster. Tom...
A nice treatise Craig...I enjoyed reading it. It sounds to me as though you are a bit of a PID enthousiast, as am I. I enjoy playing with PID, whether it be...
Thanks for the help guys!Is it possible to count the number of measurements that have been recorded into EEPROM?For example using putEEPROM() to record for...

I had posted PID code for BX24 on this forum about two years ago. It was in "Files" area but now the whole area looks different. But it must be there...

Hi everyone, I've been trying to learn the differences between PStamp code and BasicX code with this project. I'm converting the provided code from Parallax...

... Most piezo sounders have a narrow useful frequency spectrum; those I've handled seem to like 2KHz, or so. If you intend to produce musical sounds or...
Anyone? I've got some newer code... Now I think it might be variable types, since it doesnt enjoy using bytes for some of them. ******************** ...
