Hi,

I want to use MCP4921 a 10bit DAC. I want to connect it to PIC16F877A.

But I have confuse on PIN CS on MCP4921.. Is it have to connect to pin RC0 or RC1 or RC2 or RE1?

Someone who had us ...

Hi bungee-

I still don't understand your coding on http://www.ccsinfo.com/forum/viewtopic.php?p=115112#115112. Is it for remote control flight?

1) I have compile and try to simulate in proteus I ...

ok

Because I have more than 2 RC servos, I have to generate PWM manually using loop.

Exp for 1 servo:

int i;

void main()

{
while(1)

Hi, all CCS member and Happy new year!!

I am a student at Singapore, I got a project about controlling 16 RCservo motors on PORTB & PORTC. Currently I am using 16F877A & 20MHz. I can contro ...

hello.. below is my code for my butterfly wings.. i use 2 motors and each motor have 2 limit switches...

the motor do not have same speed.. so my sequence is..

hi..

i want to ask u a question please...

about servo.c library... which 2 pins i have connect to give signal to my 2 servos and i am using PIC16f877a 20Mhz..

and if i want to control more ...

what if i write like this? is it correct?

#include <16F877A.H>
#device adc=10
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock=20000000) //20MHz
#use rs232&# ...

i had change some.. but it is correct how i define set_adc_channel(0) to set_adc_channel(7)?

i want to use all the ADC channel at same time.. if there is a change or not at any ADC pins.. i want it ...

ok its work Thanks~~

it not have many range.. I have to make it more range... so it can become more accurate and smooth.. can i?

actually i want to make a animtronic using potentiometer or flex ...

still cannot work.. can anyone heLp~~ thanks..

but still cannot work.. can anyone help me? is there another way?

Oo ic..

hehe~ still same.. u just remove the delay..

result still same.. ADC change but the motor stay at 90deg..

if i put this code it work.. but without ADC.. u just call the function

void servo1_0(void)
{

for (i ...

yes i have change the code that Matro gave..

The ADC change but the the RC motor stay at 90deg..
