Do you think that stuff is still around?

64128N SPI communications


I've been using an earlier version of the 64128N GC BC 3LP displays. I could communicate to the display via SPI if I shorted J1 and J3 together. However with the later versions of the display I am receiving now, there is no J1 and J3 pads to short.

Can you confirm if the later versions also have SPI capability and if the jumper is no longer needed or if there is anything else that is needed to enable SPI communications? The exact part number of the new display that I have is - Displaytech 64128N GC BC_3LP 220109... (More)
