Hi,
I am trying to get my OLED (NHD-1.5-128128ASC3) works with a Teensy 3.6 using the following library:
https://github.com/kirberich/teensy_ssd1351 and using the examples provided with it.
Despite I tried a lot of different settings I can not get anything out of it, the display seems completely dead.
I've already checked twice wiring and it seems ok, I've checked with my DMM if the display is receiving the right voltage (about 4.75V) and checked CLK, SS, MOSI and MISO with an oscilloscope, and they seem to have sense.
So I cannot understand what it is wrong with that.
Anyway I have noticed that CD and 3Vo seems have a shortage with GND (checking using the continuity checker of my DMM), even if CD and 3Vo are disconnected, so I hope this is not an issue.
Here it is my wiring:

I've already tried to
downclock my Teensy at 24MHz or to use the define SLOW_SPI in order to reduce the SPI speed at 15MHz, I've also manually change the SPICLOCK to 8MHz, but nothing the display seems dead.
Could you help me?
Thank you.
