Any ideas please? It simulates as expected but not in real life....

I seem to remember I souldn't use the LCD on Port A of ECIO not sure why though...


James :-}

Can you please mention which ECIO you are using? I mean ECIO-28 or ECIO-40

Please add the following code in the beginning of the flowcode in the c code box... Please let me know is that worked or not.
Enamul

The ECIO 40 - I'll check your fix now...

Nope still prints '?' in real life.

The file is here - I'm just trying to see the numbers selected on the slide switches on the LCD to test it...

This should certainly work.. Try this code together with earlier one..if not work then definitely USB issue...In that case use all RA pin except RA4 use from other port..
Enamul

Hello James,

If Enamuls code doesnt work i would try using a different port as i remember there being a problem with one of the pins on PORTA being attached to the LED or is Vin, i cant remember why, it would be worth checking the 18F4455 datasheet to see if these pins can be used.

Thanks for the help all but I gave up and set the LCD on Port D and the Switchbank on Port B and it works fine!

(Plus I don't understand what Enamul is actually doing and don't want to look stupid by admitting that!)

Best regards,

PS - I will check if your version later Enamul but the excitement of seeing the numbers working OK on the display is too exciting...

ECIO-40 uses pin RE2 for USB LED, not a port A pin. It is an ECIO feature, not of the PIC so this will not be mentioned in the Microchip data sheet. It is listed in the ECIO data sheet. (For ECIO-28 it is pin RA5)

Hi James,
Would you like to give this a try please.
Just to see if it works on port A.
This may not still work of course.

Hi Martin,

It doesn't work I'm afraid but it does something different now.

It scrolls solid blocks of 5x7 with question marks randomly placed...

Thanks for trying anyway - I'm sticking to Port D for the LCD and Port B for the slide switches...
