Is an int signed then unless you specify unsigned int or int8? This could be a problem, i'll change this on monday and check the result.

Haven't had chance to try this bit yet, but here is the c ...

Sorry, left work at Lunch time.

As for the LST code from 0045, i won't be able to get that until monday, so i will post it then. (sorry didn't notice it jumped back up to 0045!)

I appreciate all the help you guys are giving.
Ttelmah, thanks for your suggestions. I will look at using a timer i think.

Here is the full list of the code, it pretty simple really..

// SEOS H ...

Yeah, that does account for some of the extra delay, but not all of it.

I suppose i will just have to say it is one of those things, but i hate to do that. It would be better to know.

Yes certain of X=5 because if i have a value in PosServo0 then it moves the servo by the calculated amount. If X=0 then this would not happen, it would just generate a HUGE pulse.

Puzzling..!

Hmmm,

I don't think so.. This delay is triggered by an interrupt every 16.5mS so each time this delay is triggered the ISR has just started and this delay is over well before the next ISR 16.5mS la ...

Hello,

Here is a snippet of code that generates a pulse of a varying size dependant on the value of PosServo0.

I need a minimum pulse of around 900uS to drive a servo but i get some very strange ...

Hi Guys,

Now these questions may sound daft, but i must start somewhere!!

OK

No. 1 With a 5v internal reference on a 16F873 (10bit) will the result of a READ_ADC automatically be within the r ...

for completeness - this is my actual code inside the isr

#int_TIMER0
TIMER0_isr(){

output_high(PinServo0);

delay_ms(1); // the minimum on time for servo
...

next problem...... Very Happy

i want the RTCC to interrupt every ~17ms

at the moment the setup of the timer0 is

setup_timer_0(RTCC_INTERNAL | RTCC_DIV_256);

in the device file it sa ...

Excellent, thanks people..

Suspect my project will kick out a few more problems yet!!

Be back soon...

John

For those who know what they're doing....unlike me!

Hello people,

If i compile this simple bit of code

//SerialServo.c
//----------------
#include <SerialServo.h>

#define ...

Just figured it out! It is 0x4F times 12 gives 960. So the value in data_byte multiplied by 12 gives the on time for the servo (plus the 1ms delay)

Ta..

Cheers Doug,

I will have a look at that... Seems easy when someone explains how to do it. I wouldn't have known where to start!!

One question. Where does the value 12 in the last bit of code com ...

Hello all,

I want to control 3 groups of servo motors, essentially i can just assume as far as the PIC is concerned it is just 3 servo motors..

I am completely new to this and two days ago i did ...
