my project Capacitive Sensing LED dimmer 12F1822 via PWM

[visnja30]

Hi,
if someone can explain how using the program of Mr. Heckler to make that ports A.0, A.1, A.3 be the same as the touch sensing port A.2
For example, when I touch the port A.0 then lights are increases , and when I touch port A.1 to reduce the light LEDs.
I do not understand how to run the port A.0 and A.1 to be a touch sensor.
Best regards

If you look at the datasheet for the 12f1822 you will see that only pins A.0, A.1, A.2 and A.4 have cap sense capability.
You will have to work with those pins.

Also, as Charlie and others have pointed out, I would not do the Zener regulator. It is inefficient and does not allow one to draw more or less current as your circuit might demand, at least not efficiently.

The Zener regulator idea was a bad one... especially with the LDO regulators available for about the same cost and parts count.

My mistake,I mean portA.4 but wrong I write on post.

Have you been able to get the circuit and/or code working as I posted above?

Once you get it working as posted then you can work on getting other features and customize it as you want.

Right now each time you touch the cap sense pad it changes the LED brightness using PWM

Hi,
today I receive a free samples from Microchip and I got a big surprise.My EasyPIC5 development board can not program PIC12f1288 so I can not to try your code.
I have another PIC16f724 with capacitance sensing module But I dont have a working example for him.I try to adjust your code to PIC16f724 but I have a error while compiling.

ASM ERROR symbol not previously defined (TMR1) (0) error 113

When I compiling your code for 12F1288 I dont have this error.
