EasyPICPro7 + Riverdi Click + Riverdi 2.8" display

[PaulAtComco]

Hi,

I'm new to PIC but have been in software for 40+ years... and we have just bought the hardware: EasyPICPro7 + Riverdi Click + Riverdi 2.8" display ( MIKROE-2156 ). I've developed Bluetooth and eInk display applications on the EasyPICPro7 - all rather smoothly.

I cannot get anything to render on the LCD.

Hardware
* Vanilla EsyPicPRO7 board ( only jumpered it to select 3.3v )
* Riverdi Click in Mikrobus click position #1 ( no settings or jumpers changed )
* Cabled up to Riverdi display

Project
* New project - none of 'my code' - only the boilerplate generated by VTFT
* VTFT has only a single 'graphic line' drawn on the display
* compiles and loads with no errors

Absolutely nothing happens on the LCD. The only life is a momentary 'flash' of white when I power up the EasyPICPro7 board

I may have a ( accidentally ) left a few switches / settings on the board that I've mistakenly inherited from previous projects - but I have not seen any specific EasyPICPro setup steps required for the Click

Any hints or suggestions welcomed.

Cheers

Hi,

Thanks for the prompt response.

I have seen the article you refer to and analysed it ( and tried it - and many versions of it ).

I'm quite happy that I may have a fundamental misunderstanding of the way all of this works but...

With this equipment:
* EasyPICPro v7 board
* A Riverdi Click
* A plain Riverdi 2.8 display

I cannot find or make any VTFT screen definition or board definition or code, that causes anything to happen at all on the display. ( I see oscilloscope activity on the SPI pins and the display backlight is on thats all - my code does not even return from FT800_Init() and nothing displays.

Its not for want of trying, I have read
*the FDTI FT800 datasheet
*the Riverdi 2.8 RVT28AEFNWN00 datasheet
*the Riverdi click Schematic etc
*the PIC18F87K22 Datasheet
and set up the attached board definition as best I could.

I'm assuming that what I'm trying to do - create a screen in VTFT and build and run it with none of my logic - is actually possible with the resources I have ( described above ).

Any assistance is very gratefully received; I dont seem to be able to find or create anything that will simply display anything I designed in VTFT on this combination of kit. ( Please dont assume that my fist thought was to ask you guys - I have been round every sample I can find and read up on it - and still I'm missing something ).

If you can suggest an alternative hardware arrangement that will allow me to drive a Riverdi 2.8 display - I'll happily get the bits - at least I will have something to build on.


Cheers
