Hi Guys, I will be working on a motor control project a bit later this summer. The motor I will be driving is 6 Volts @ 8 Amps. I only need it to run in one direction but I would like it to be variable speed. So, I figure I could use PWM output from a PICAXE and feed that into a logic level...

Hi guys, I do a lot of labeling here at work. I print the labels, I take them off the sheets, and I apply them to the packages - very boring, very tedious, and very expensive. A while back there was some talk here about an inkjet printer, or ink jet printing head, or something to that effect...

Hi guys, I am having a tough time working through this and I don't know why - it should be simple for me. I am working on a routine to run a stepper motor. I need to accelerate the stepper up to speed and decel it back down when required. I understand acceleration as a change in velocity...

Hi All, I am working on a new project that will need to be fairly accurate regarding real time. I am not worried about tracking calender days and such, but rather accurately knowing when 48 hours have passed by. If it's within a few seconds, that would be accurate enough for this application...

Hi all, I believe the pending .net product will do this, but I am wondering if there someone has a circuit for using USB to communicate with PICAXEs? To clarify, this isn't for programming the chip, but rather in-application communications. THanks again! Chris

Hi All, Is there a document or anything that shows which commands can be used with the assembler output? So far, the only thing I have found is that the Serin function will not work but no indications anywhere on the other commands. Thanks Chris

Hi everyone, sorry to ask this question again, but I am hoping to find the solution using PICAXE so I don't have to learn yet another programming language :-( Here is my problem... I need to create a pulse stream that can deliver up to 50,000 pulses per second, each about 5 usec in duration...

Hi all, I am working on another high capacity I/O device using a 28X and MCP23017 chip. I did one already with the MCP23016 chip, but this time I want to make things much more compact and the 23017 seems to be much better laid out for this. I want the system to work like this... All inputs...

Hi Group, I have an application in mind that I think will work with PICAXE chips. Everything I need to do is going to require very high speed so I will have to overclock to 16MHz and or use the assembler function output. I also need to have high speed communications between a PC (Windows) and...

Merry Christmas to all, and thanks to all those who took the time to help me out with my crazy projects this past year! A really big thanks is extended to AndyP and Hippy, I learned a ton from you guys! Chris

Hi all, knowing that I can use a PICAXE to control an R/C servo, I am thinking this may be just the ticket for something I am working on. I need to move and hold a lever in position for a device. I tried to use 4 pound pull solendoids, but they just don't have enough pull to move the lever...

Hi All, Getting more interested in this concept of using the assembler output function. I believe currently, using BASIC, these chips can do about 10,000 instructions per second. I am wondering what that would be if I used the assembler output? THanks Chris

Hi All, This function of the editor is very interesting to me. I have always wanted to work in assembler, but never took the time to learn it/use it. I would like to tinker and learn using this feature as it can convert BASIC to Assmebler - a great side-by-side comparison and learning tool...

Hi Folks. I love the new editor with the colors and such - makes reading a program much better. However, there is a small problem. When exiting the software, it always asks if I want to save the "Blank" file that is automatically opened when the editor starts up. Nothing big, just...

Hi everyone, I am spending some time try to organize all my PICAXE project hardware. I ran across a PIC16F628 mixed in with all my other PICAXE stuff. However, I can't determine what it is for? Does anyone know if this is one of the support chips for something else? Chris
