Title: A10-OLinuXino-LIME-UEXT for both UEXT and LCD?
Post by: fiosca on February 15, 2014, 05:22:18 PM
I need both UEXT extension and LCD on my A10 board.

From  A10-OLinuXino-LIME-UEXT  product description, it's not clear if connecting to GPIO-1 I have only UEXT connectivity or both UEXT+LCD.

If i need both, do I have to buy 2 expansion boards (one connected to GPIO-1 and the other to LCD-CONN)?

Thanks!

Hello

They should be both available on LCD-CONN. If you get one of these https://www.olimex.com/Products/OLinuXino/A10/A10-OLinuXino-LIME-UEXT/open-source-hardware, you can connect both.

You might by right though, because I don't know if you can actually use both at the same time.

I have to check the schematic and GPIO description

Ok, found A10 gpio connectors pinout:

https://github.com/OLIMEX/OLINUXINO/blob/master/HARDWARE/A10-OLinuXino-LIME/A10_Lime_GPIOs.pdf

LCD-CONN doesn't have right pins for UEXT (uart, i2c ecc), so the right answer should be:

If you want to use both UEXT and LCD connection you need to buy two A10-OLinuXino-LIME-UEXT boards,
one connected to GPIO-1 and one to LCD-CONN.

Due to the fact that A10 is quite new and there's lack of documentation,
can somebody from Olimex confirm that?

Thanks!

Hello fiosca
You are right.
There are no UEXT signals in LCD_CON header !.

Olimex, where are there schematics for the expansion board ?
