Two OLEDrgb Pmods on a single Arty A7?

[rehsd]

Can I use a pair of OLEDrgb Pmods on the same Arty and access them both from the same MicroBlaze? I have a single OLEDrgb running now, and I'm thinking of adding a second one.

Hi @rehsd,

Yes, in general you should be able to use multiple of the same Pmod as all Microblaze would really see is that there is more than one AXI Quad SPI IP (in the case the Pmod OLEDrgb). The two IPs would need to have different names, but the names can be changed directly in the block design.

As a caveat, I haven't attempted this with the Pmod OLEDrgb in particular, but you would be able to add the extra IP in Vivado and see the bitstream still successfully generates (and if the SDK/Vitis still successfully builds the project) as much of the debugging work can be done prior to actually purchasing anything.

Thanks,
JColvin

Sounds good. I'll give it a shot. Thanks!

@rehsd - Good to know that you got your PMOD OLEDrgb to work. Today, I also got my PMOD OLEDrgb working. It is good to know that it is possible to add 2 PMOD OLEDrgbs to the same FPGA board, if needed
