OLED SPI Chip Select (CS)
« on: November 10, 2015, 12:55:19 PM »
Hello,

I am using NHD‐1.5‐128128UGC3 Graphic Color OLED Display Module utilizing SPI serial communication. The documentation is very vague regarding manipulation of the CS (Chip Select) line. My question:

Does CS need to be Activated/Deactivated for each command/argument transmitted or is it possible to transmit multiple commands/arguments with CS being activated once upon start and deactivated at end of the process?

Your help is greatly appreciated.

Hi,

You should be fine grounding the CS pin on the display, it will still work.

Hello,

I highly recommend you check out the controllers datasheet, see page 20 - 21:

Table 8-5 and Figure 8-5 should clear things up  ;)
