Thank you Biljana, I have received the license number.

I like the idea of combining the graphic designer into the compiler IDE. However, I see a problem for those of us who already have a registered copy of Visual TFT. My copy did not have a serial number, but required downloading and running the Visual TFT Reg.exe, this program does not reveal the seri...

The reference to power sources on page 7 and the legend on the board, state external power sources of 7-23VAC or 9-32Vdc can be used.

Pages 8 and 9 state in bold 7 - 12VAC or 9 - 15Vdc

I don't see any decoupling capacitor on your breadboard across the power supply.

Not having this can cause unpredictable results as the Pic becomes sensitive to noise on any pin and can give different results form Pic to Pic.

Brilliant, thanks.

I'm using the ECCP Special Event Trigger mode to start and ADC conversion as stated in the 16F690 datasheet.

In the simulator the DONEGO bit doesn't get set when CCP1IF gets set.

Is this due to the simulator only being coded for the older Pic parts that have a CCP2 which starts an ADC conversion?

Are you sure it just isn't flashing too fast for you to see?

How does it look in the simulator?

I see some one else had a problem with using sbit's, so I wonder if your problem would be solved if you used a struct for the GLCD bits.

Try changing sbit GLCD_CS1 at LATB2_bit; sbit GLCD_CS2 at LATB3_bit; sbit GLCD_RS at LATB4_bit; sbit GLCD_RW at LATB5_bit; sbit GLCD_EN at LATB6_bit; sbit GLCD_RST at LATB7_bit; to sbit GLCD_CS1 at RB2_bit; sbit GLCD_CS2 at RB3_bit; sbit GLCD_RS at RB4_bit; sbit GLCD_RW at RB5_bit; sbit GLCD_EN at R...

Have you traced what happens if you just use the simulator, do you see 'a' transmitted?

What happens if you temporarily change the code to

Would accessing the structures via a pointer make any difference to the way the compiler optimises code? Just thinking, index 0 should be available as an array is just passing an address plus index, if a pointer to either the struct or array is passed this might solve the problem. Maybe even an arra...

How are you declaring your variables locally or globally?

Could you post a snippet of the call and the function code?

Which Pic24 are you using?

There could be many reasons why the compiler will optimise out code.

For those who make their own libraries, this would be a nice extra to allow function overloading.

I think it would be useful to provide either the hex file and preferably the source as well for the preloaded demo software provided on these board. I sent an email about this, but I think people thought I was referring to the programming software, when to be absolutely clear I'm referring to the pa...
