Hi,

I just opened the [nwazet repository on BitBucket.

There, you will find the C# libraries, the C drivers and the Eagle designs for the [nwazet Netduino GO! modules.

Enjoy!

Hi Cuno,

I'm going to expand on what Bertrand wrote a bit and take your questions one by one

If I understand correctly, your touch display has its own microcontroller, between the display and the Netduino Go. Is the "SPI up to 40 MHz" between display and your microcontroller?

That's correct: the display has its own STM32F2, servicing commands from the application running on the GO! mainboard received / sent over SPI. In turn, the display module drives the actual LCD screen and handles the interactions with the touchscreen.

What exactly is the higher-level protocol on top of go!bus, between Netduino Go and your display module? Are the drawing primitives related to common .NET abstractions?

I wrote a generic lightweight message serialization / deserialization system for passing messages / objects (in network byte order) between a C# app and the C code (and vice-versa) interpreting the commands. The buffer containing the serialized messages is used by SPI directly.

Could your display be used from a Gadgeteer mainboard as well, let's say through an SUX socket?

Yes, it should work just fine.

Thanks and looking forward to seeing the display in natura!

Thanks,

Cheers,
-Fabien.

The PIX-6T4 book is not quite finished yet (Bertrand and I have been insanely busy these past few months). We'll likely release what we have written so far as an open source book as soon as we can breathe a bit. Cheers, -Fabien.
