PoKeys / Must be doing something wrong?

« on: June 19, 2010, 08:08:37 PM »

I have a couple of the Pokeys55, and they seem fantatic value and incredibly clever little things and are lovely and tiny in size.
I am trying to use them and Mach to switch some relays via darlington transistor IC's.
There are 12 circuits to switch in total. 8 work fine.
I cannot get the other 4 to switch? I have used a multimeter and cannot get the Pokeys to output on any other pins (even though they are set-up exactly the same in the control panel) - am I missing something here?
After some issues with pin 4 (I think - from looking at the paperwork) I have therefore not used pin 4 nor 13.
I have 1,2,3,5,6,7,8,9 all switching fine.
Cannot get any others to output 3v nor to switch. Even tried the other 2 Pokeys just in case I had a faulty one - am I missing something here - is there a limit I have not read about, or am I doing something wrong? Have I something else to set in Mach.
Been working on it for 11 hours now, and getting rather frustrated!!

Screen designer tips and tutorials / Holding down a Keyboard Button or MousePress

« on: June 06, 2010, 06:24:23 PM »

I have designed my screens for an application I am working on, and need several buttons to operate relays whilst a keyboard button is held down and/or mouse click is held down. I have the screens and operate the relays using some simple VB. I can easily toggle them on and off, and all works fine.

But I need them to hold on only whilst the button is pressed or the mouse clicked - Does anyone know a way to do this with the Brains or VB or anything? I don't actually use an X Y Z axis - it could be a bodge but can the jog buttons be reused if there is no proper way to achieve what I want?

I have searched the forum and cannot find an answer although I did see similar questions posed several times.
