BrainPad Schematic

#1

I have a Version 1.0 BrainPad (White board with three Touch Pads).

I ‘thought’ I had a schematic but I cannot find it on any of my PC’s.

Does anyone have the PDF that you could send to me or a link to a source.
I checked http://www.ghielectronics.com/downloads/schematic/ but it is not there.

Thanks!

@ willgeorge - What information do you need from it?

@ John -

The pin ID’s used by the N18 LCD (I am assuming it is a N18

Not having luck trying to Initialize the LCD for use with the new TinyCLR.
(Not smart enough to get the SPI working)

I had it working with NetMF 4.3.8.1

The BrainPad I have is the first one you offered.
Not a big deal… I just like to check things against a schematic so I am using the correct pins.

Thanks for the reply

@ willgeorge - It is the N18. It uses SPI2, PB12 for CS, PC5 for RS, PC4 for reset, and PA4 for backlight.

One last question

From G30 SoC Datasheet
Any pin with no name, function, or note must be left unconnected.
PB12 for CS - Data sheet shows White.

Only something I noticed. Not trying to be a pain.

Thank You!

This confused me before but I think it refers to the WHITE box adjacent to the pin number such as 5, 6 and 7 which have no PA/B etc description. PB12 for me simply has no other function than being a GPIO pin.

yes, agree, it’s just that there is no secondary function

@ Dave McLaughlin -

I took the words literally. “or note must be left unconnected”

At least I understand now.

#9

The next datasheet update has already added a header of “Pin, Name, Function” above each column. In this case name refers to “PC13” or “PB9” for example.
