Yes, it says that pointers don't support "." operator. That's why I did the workaround.
http://www.mikroe.com/forum/viewtopic.php?f=88&t=29243 this is where I have asked for something similar.

As far as I know you can do this using bitwise operators: -XOR (^) : let's say this is your byte: 0100 1111. You want to change bit 6. you do 0100 1111 ^ 0100 0000. -> 0000 1111. -OR (|): your byte: 0000 1111. you want to set bit 6: 0000 1111 | 0100 0000 -> 0100 1111. -AND (&): your byte 0100 1111. ...

@ananth.antony: have you also tried a hardware test? Maybe the virtual sim is working ok but a practical test doesn't. I have tried this example both with easypic6 and ISiS on a 18F452 PIC. Worked ok for me

The PWM is a built in feature. So you don't get to choose pe desired pin, you get to use the Microchip has assigned. I believe it's the RC1 and RC2 pins. The PWM1_init() and PWM2_Init() take care of the initialization of the modules.

Are you sure RA0, RA1, RA2, RA3 are pulled down?

How do you want to send the data? I mean, are you doing to write your code for accessing serial port and sending and receiving data, or do you have some other idea? On the pic part it is easy. You can use mE library for UART communication. The help files will give you everything you need.

Well, we do not know what's the code in mE's library. I believe it set's the OSC so you don't have to. But I am not sure.
PWM1_init initializez the first module. I don't know how many modules does your pic have. You should check the datasheet for that.

I have sent you a PM with a link towards the video.

You have to press repeatedly or keep a button pressed for a little while to notice the change. After I download the hex into the PIC, the RC1 and RC2 leds are lighting very dim. When I press a button it either gets dimmer or stronger. As I said, it is not instant. You have to press repeatedly or kee...

I really don't know. I have tried this same example and it worked for me. I used PIC18F452 and easyPIC 6. All I have changed was the configuration for PIC's I/O pins.
I have checked it with an oscilloscope to see how the signals change and everything is ok.

Ra0-Ra3 are used to increase or decrease the length of the pulses. They modify how long does the PIC keep the pin in High state and how long in keeps it in LOW state. It acts like a chopper.
Thanks for the Proteus.

Maybe. Anyway, is everything ok now? Or there still is weird stuff goin' on?

if (ra_bit) = If(ra_bit==1)
When you press the button 5V must get to the pin of the PIC.

If I may, what software do you use to draw the schematics like the one you've posted? Thank you.

You're welcome. I still don't know why it blinks, but I use only 0 or 1 for the colour setting.

I have reviewed your code. I use EasyPIC6 with PIC18F452 at 8MHz. Except the configuration bits for the GLCD and pin configuration for the 18F452 I haven't changed anything and it works ok for me. Oh I have used While (1) {} not the do while(1). I don't know if this make any difference :) And you ha...

Right. Ok then, if all the other analog inputs work as they should, then there is something wrong with the 2 problematic ones. As far as I have read the code, there is nothing different between reading the inputs so you should turn your attention towards hardware part. Maybe something interferes wit...
