script to control Digital IO supplies from Protocol viewer

[arang]

Hi,
I can find example scripts to Read/write  from the protocol viewer. (Read(address),write(address)).

 have to set the DIO27 supply to 3.3V and vary it programmatically .
I couldn't find any sample scripts to control Digital I/O supplies for Digital discovery!
All the examples/references,  I found  are Analog discovery Analog supplies controls.
Can you please point to manual/reference.
Thanks

Hi @arang

See the link:

@attila
Digital Discovery has 16 I/O pins.
say I am using DIO24 
To enable output - what is the mask?

is DIO24  set as DIO -0 in the code? i.e  mask bit LSB 0th bit?

dwf.FDwfDigitalIOOutputEnableSet(hdwf, ? ) 

Thanks

Hi @arang

Yes, see the manual and examples.

Found it. thx

@attila
Can the DIO pins voltage changed individually?
Say DIO 25  = 3.3V and DIO 27 = 2.5V.
When I tried using the Supplies tool, that all the pins has the same Digital voltage.
Is this hardware or software limitation. or Am I missing something?
Thanks

Hi @arang,

The voltage setting is for all pins; this is a hardware limitation as the Supplies sets the VCCIO_PROG voltage for the banks that all of the pins (DIO and DIN) are connected to.

Let us know if you have any questions.

Thanks,
