Topic: Use MPCIe

The content of this topic has been archived on 30 Mar 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hello everybody


I have GW3526, I need pins to control a phase shifter, I think about putting an expansion board on the MPCIe port (as pictured) and then controlling these pins, I need to have binary values and then send it to my shifter phase.

I dont know how i can do that!? if it's possible.

The green board from your picture is just an adapter, not pci-e I/O controller.
You can use some I2C GPIO expander as the ZBT WG3526 supports I2C.

Thank you for your reply, I think I understand what you mean,
Do you think if I just use a GPIO expander such as this: http://www.diamondsystems.com/products/dsmpegpio#quote

it's going to work ?

I just want to manage 6 bits and changed their states.

If you know how to use this card (driver?).
I2C GPIO expander would be easier to use.

OK thank you @pepe2k, i will try I2C to GPIO

I will publish the results.
