connectEVE sample code for ATmega32

[josempita]

Hi all,
So I've been playing around with the easyAVR development board which is pretty cool and "easy" to configure ... except when it comes to integrating with a connectEVE tft screen... I've tried the demo version of visual tft to generate the initialization code but I just can't seem to initialize the display correctly with the ATmega32 which comes with the easyAVR dev board... any chance we could get more avr samples for connectEVE, I see there are some example projects for xmega though ...

Thanks

Hi,

I attached Visual TFT Hardware pattern for EasyAVR v7 + ATmega32 + ConnectEVE.

You just need to copy that XML file into:
Visual TFT Installation folder/Board Defs

and you will be able to choose that Hardware pattern in your Visual TFT and create some project for ConnectEVE.

As regards of ConnectEVE connection with EasyAVR v7:

- CS: PA5
- RST (PD): PA6
- SCK : from mikroBUS socket 1
- MISO : from mikroBUS socket 1
- MOSI : from mikroBUS socket 1

Best regards,
Marina Petrovic

Good morning,

Thanks for the xml.
I connected the EVE as mentioned in previous post an made a very basic Visual TFT screen (just a different background color and a button). I can't get it to show anything. The connectEVE just shows a white screen. I does seem to initialize as it flickers a bit after reset. Using an oscilloscope I checked the signals and even though I don't know the exact data that has to be transferred it seems to be okay. O at least the SPI communication works.

Any suggestions?

Kind regards, Jan

Hi,
Have you been using the same setup (board, mcu) as above?
Can you post the code here for review?

Kind regards,
Petar
