Hi, I want to use on pic 16f1827 capacitive input for some buttons and i don't know how ! Can you help me please with how can I configure pic for these inputs and how can I read these inputs ? I am using PCHD Compiler 4.126
Thank You |

Did you read the datasheet that covers the CTMU?
Did you download examples from microchip's website?
Did you look at the schematics for their demonstration kits?
Did you google for anything on the topic?

Yes I did, all instructions are in assembly, and I don't know assembly. |

More to the point, look at #use_touchpad in the manual. 
Best Wishes |

No. You didn't.
Microchip has 7 examples most if not all (I didn't look at them ALL) are written in 'C'.

Yes, i read those examples. I understood the principle but i don't know the syntax of functions in CCS C.
I am new in pic's world. Until now i played on an Arduino with some leds for school. I've made a led cube 3x3x3.Arduino is much more simple than pic.
I have made a little program and it's not working :
| Code: |
#include <main.h>
#use touchpad(threshold=5,pin_a1='J')
void main()
{
setup_timer_0(RTCC_INTERNAL|RTCC_DIV_2|RTCC_8_BIT);
setup_timer_1(T1_INTERNAL|T1_DIV_BY_1); //524 ms overflow
setup_timer_4(T4_DISABLED,0,1);
setup_timer_6(T6_DISABLED,0,1);
setup_comparator(NC_NC_NC_NC);// This device COMP currently not supported by the PICWizard
setup_oscillator(OSC_500KHZ|OSC_TIMER1|OSC_PLL_OFF,0);
char c;
enable_interrupts(GLOBAL);
while(TRUE)
{
c='a';
if ( TOUCHPAD_HIT() )
c = TOUCHPAD_GETC();
if(c=='J')
{
output_high(pin_b7);
delay_ms(500);
Output_low(pin_b7);
}
}
}
|
this is the main.h
| Code: |
#include <16F1827.h>
#device adc=16
#FUSES NOWDT //No Watch Dog Timer
#FUSES INTRC_IO //Internal RC Osc, no CLKOUT
#FUSES WDT_SW //No Watch Dog Timer, enabled in Software
#FUSES NOBROWNOUT //No brownout reset
#FUSES NOLVP //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#use delay(int=500000)
|
Can you help me please ? |

The bottom items are all clearly discussed in the helpfile that comes with PIC-C.
The function calls to things like
enable_interrupts and setup_timer_4 and so on are ALL explained in the help manual.
Did you read through those help file sections yet? (I'm guessing you have not.)
It sounds to me like you don't understand 'C'. I would recommend you take a class or go to the library and read up on the language.
Cheers,
-ben

look , i'm just asking some help , the deadline for my project is arriving, i don't have time to read books of hundreds of pages . my question is simple "how can i set a pin for capacitive input" .
You can help me or not ? Can you tell me what's wrong or not ? It's simple. |
