The picaxe 28X1 has some very cool memory features that can be used to free up program space or to give your robot a more convenient user interface. This post … Read more

hardware not found error

mintvelt's picture

Hi,

I run the picaxe programming editor on windows XP in a virtual machine (parallels desktop) on my OS X laptop. The serial connection to the picaxe 28x1 works fine when I'm just communicating using hyperterm or when the picaxe sends debug info.

When I want to upload a program to the chip, it usually takes 4 or 5 tries to get it right. The larger the program, the more it fails to load.

So i decided to use the command line compiler for mac OS X. Now the uploads are very stable only a new problem appeared.

Continuous Rotation Servo & Picaxe

Ok, so I finally got all my gear set up to build robot numero uno, but Im goin friggin nuts trying to control my continuous rotation servos from parallax. Im using a picaxe 18x to produce the code, but no matter what pulsout or servo commands I use, my servo's only go clockwise.I NEED them to be able to go counterclockwise  for my differential drive train to work right. I have read every post on LMR about servos and have tried a lot. I have read their parallax data sheet and that they should respond based upon the pulse width, but no go.

Picaxe 28 and servo question.

Hi all :)

Im just getting started in robotics and just joined this forum. I got inspired by the great "start here" project you have here. I am starting with a similar project for my first robot, but I would like to make a few changes. Instead of using motors to drive the robot I plan on using servos modded for continuos rotation. The robot will have 4 servos. 2 for moving around, 1 for panning the head and the last one for either operating some sort of manipulator or panning the head up and down.

I have some questions though, which I hope you can help me with:

I think Picaxe is a great product. But somebody should kick their web department. Sometimes people buy a Picaxe product in another shop, and do not get the manual … Read more

Servo and picaxe: need resistor ?

Nicola's picture

hello, i'm trying to use a servo with my picaxe. I tried it on Arduino before, and it worked just connecting the pins at the right position, without resistors.

now i just connected the same way on the picaxe, and it doesn't move.. I then remembered that in the "start here" project, a resistor was used.. So the question is: is it necessary? why do i need a resistor? and how do i wire it ?

Another thing that is probably messing up.. i have the darlington chip there.. shoud i remove it?

 

thanks :) 

Driving servos

Here ( http://letsmakerobots.com/node/80 ) Frits had mentioned that either Arduino or PICAXE can control such and such number of servos. I'm pretty new to microcontroller world, so maybe my question will sounds a bit stupid... but I don't really get what we mean by saying "can only control X servos"? Does it actually mean, "platform X can have up to N serial outputs"? Because, AFAIK that's what servos are, aren't they?

Now, I can understand that PICAXE has also limitations due to the built-in Basic interpreter; but why Arduino?
