You have to set bit 2 to 0 T1CON = %00110000 for external oscillator.Can I still use "T1CON=%00110100"?
The above has been copied from the code you have posted. This code, without correction, will not compileCode:gosub Debounce_AutoRepeat if (triacdelayMaxDelay, fullbright=1 ' set the full brightness Flag endif

All progress began with an idea
|
I checked the datasheet for Bit2, will timer1 be running at 4MHz & TMR1 interrupts be happening at 16.383mS?Originally Posted by aratti
Also can bit2=0 run timer1 or it won't work at all?
|
Progress........
OK, I have now changed the code to work on 16F676. Code is attached.
I have tried different values for triacdelay from 8000 & downwards as in lampdim.bas to as high as 15000 & downwards, but I am not getting satisfactory results for my fan speed.
It woks fine at full speed but when values start reducing, the fan speed reduces quiet a lot at the first step only. Any ideas as to what values I should try with?

Hi,
IF my old memory is right ... your motor is not one of the so called " universal " type ... AND modifying its speed is not so simple as for your electric drill ...
as speed is based upon the mains FREQUENCY ...
BTW ... This:
Shows you did not understand at all the way steve's DIMMER ( never been a motor speed controller !!! ) works ...2) Confirm if in Dimmers only Positive half is controlled (and WHY)?

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

It does say it can be used for motors in the code lampdim.basHi,

Also, I am not using this code for previous motor control project, it is just for controlling speed of my ceiling fan, not any stepper motor or anything like that.
I am trying to understand how fan/light Dimmers work & what is the benefit and use of half wave & full wave. Which one can be used for inductive load & which is better for resistive load?

Soooo ... if you already know the things ... why do you ask such questions and why doesn't it want to work properly.
excuse me if I have disturbed you ...

A little explanation would have been more appreciated than this. I said it because I read it in the lampdim.bas " ' This program is use to dim intensity of an AC line loadSoooo ... if you already know the things ... why do you ask such questions and why doesn't it want to work properly.
excuse me if I have disturbed you ...

' like lamp, motor and other. Developped for 60 Hz line."
