It´s possible to use a serial LCD with FEZ Spider? How? Any example?

like: http://wiki.tinyclr.com/index.php?title=Alcohol_Gas_Sensor

Thank you

Yes you can but why?

It can be wired to the extender module.

UART can be done on socket types U and K (K adds handshaking). Pins 4 & 5 are TX & RX, respectively. Default serial port settings are 9600-8-N-1, but can be modified. You can use an extender module to wire up a serial LCD and write whatever byte format the display uses.

Can i use a FEZ SDK with FEZ spider and FEZ Hydra?

I would like to use this example:

FEZ_Components.LCD2x16 lcd = new FEZ_Components.LCD2x16(FEZ_Pin.Digital.Di5, FEZ_Pin.Digital.Di6, FEZ_Pin.Digital.Di7,
FEZ_Pin.Digital.Di8, FEZ_Pin.Digital.Di3, FEZ_Pin.Digital.Di2);
lcd.Clear();
int i = 0;
while (true)
{
lcd.CursorHome();
lcd.Print("Counter " + i++);
Thread.Sleep(100);
}

Hydra can run most code you see around here but not all since Hydra is open source and has a different GHI library.

Closed source: http://www.ghielectronics.com/downloads/NETMF/Library%20Documentation/Index.html

As for the core NETMF, both are near identical.

Andre, do you still need some code example to use a serial LCD with a FEZ Spider?

I’m currently playing with the Extender Module and I’ve modified the FEZ_Components.LCD2x16 code to be capable of being used with the Extender Module.
(I’d provide the code on request, if anybody is interested.)

yes sure! send for us your howto!!!

thank you!

I’ve uploaded the code including usage example and wiring information to

http://code.tinyclr.com/project/432/serial-lcd-abstraction-layer-for-hd44780-displays/

I hope that the provided information is self-explanatory.

@ GHI Team: both the uploaded code and the codeshare posting is saying “by GHI Electronics LLC”, and not “by Nils”, even though I was logged in. It also does not show up in “My Code” (so I cannot edit the infos at code.tinyclr.com). Do you manually approve those code postings or did something went wrong somehow?
