ER-OLED032-1 using SSD1322 #275

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Has anyone had success driving this 3.2" OLED display from BuyDisplay.com? I've 
tried using the NHD class definition which also uses the SSD1322, however, this 
did not work for me.

Here is the link to the device and datasheets:

maybe a hardware issue?

I can rule out hardware as I have a testing board and the display works
fine. I probably haven't interfacing correctly, thank you though.

How did you connect your display? How does your constructor look like? What 
exactly do you see?

I connected it as follows as per the data sheet on the link above and got
no output:
(I also have the other pins wired as per datasheet for 4-wire SPI)

OLED PIN -> Arduino PIN

DC - 18 - A0 - 9

CS - 19 - CS - 10

SCLK - 13 - SCK - 13

SDIN - 12 - MOSI - 11

I tried these constructors, is this meant for 4-wire or 3-wire?

//U8GLIB_NHD31OLED_BW u8g(13, 11, 10, 9); // SPI Com: SCK = 13, MOSI = 11,
CS = 10, A0 = 9
//U8GLIB_NHD31OLED_2X_BW u8g(13, 11, 10, 9); // SPI Com: SCK = 13, MOSI =
11, CS = 10, A0 = 9
//U8GLIB_NHD31OLED_GR u8g(13, 11, 10, 9); // SPI Com: SCK = 13, MOSI = 11,
CS = 10, A0 = 9
//U8GLIB_NHD31OLED_2X_GR u8g(13, 11, 10, 9); // SPI Com: SCK = 13, MOSI =
11, CS = 10, A0 = 9

I agree, this looks correct. 4-Wire-Spi include the A0 line. For 3-Wire-Spi, A0 
can be ignored.

Did you add proper caps? Unless you use an Arduino Due, do you have properlevel 
shifters?

In the display board itself - you need to set the 2 jumpers for your connection.
Those are SMD zero value resistors BS0,BS1.  figure out how to set them 
correctly.
No need for level shifters - it work fine on 5VDC.
