PICAXE28x1, Sharp IR Sensor and Infrared sensor problems

Hi everyone,

 

I'm making a robot project for my mechatronics course and I am using picaxe28x1 with an infrared range sensor that I just copied from the Start Here post here at LMR. I did everything, and exactly the same set up like what the guy did. Howeve because we are required to make at least one of our own infrared circuit, I added an infrared sensor (with a transmitter and receiver circuit and a LED indicator) circuit together with the servo and the Sharp IR sensor. I did the set up and wrote my program but it's not doing the job.

PWMOUT only on two output, that are really inputs?

Am I reading the manual (section 2, page 128) correctly? Can I only use the PWMOUT on 2 specific ports on my 28X1?

This would mean that I can't run more than two outputs with pwm, and that has to be the digital in/outs 1 and 2, so there's no hope of running it through the onboard L293D??

I must have missed something, surely there is a way around this. Pulsout maybe? I'm R'ing T. F'ing M. now, but if somebody already knows the answer, that would be helpful..

 

 


EDIT:

 

pwmout newbie questions

Why is this code not registering on my multimeter?

#picaxe 28x1

main:
pwmout 2 , 62, 250 ' 100% @ 16 Khz
pause 2000

pwmout 2 , 62, 25  '  10% @ 16 Khz
pause 2000
goto main

I measure DC over GND and digital output pin #2. And it keeps reading 0 V. Is the pwm too fast for my meter? Should I put a cap in/accross?
