Problem:
if you want to use : output_high(PIN_A); output_low() ; output_float();
you must include : #use fast_io(A);

This is incorrect. #use fast_io() is not a requirement to use those functi ...

You are making things too complex.
You say your real issue is with the touch pad.
Concentrate on that.
Ignore everything else.

Dear Mike walne.
As you say.
i must code for simple test.
...

What's the circuit with the transistor to Vref for?.

Vref for the touch, is the supply. When you send 'output_high', on the pin connected to the ADC, you charge the internal ADC capacitor to this v ...

Hi Ttelmah
This is the first time i working with Mtouch CVD.
So I do not have experience.
Thank you for the help.
This is the hardware touch button.
Please check help me :

There is also a big misunderstanding going on.

A _single_ touch pin requires two ADC inputs. The code as written implements one touch pad only.
You can re-use the same two inputs to give a second ...

You need to use:

int16 get_touch()
{
output_high(PIN_A0); //set AN0 driven high
set_adc_channel(0); //connect it to the ADC
output_low(PIN_A4); / ...

int16 get_touch()
{
output_high(PIN_A0); //set AN0 driven high
set_adc_channel(sAN0); //connect it to the ADC
output_low(PIN_A3); //set AN3 to drive low
output_float(PIN_A3); / ...

Hi Ttelmah and Mike Walne
I created a circuit test.You can see the schematic:

Reduce your code to testing the touch switch only. (Probably no more than 10 lines of code.)

Get to the stage where you know it is working correctly.

I don't have your touch switch, so there is ...

OK. Your PIC is running.

You do not have any de-bounce.
