No Data send to OLED. we checked across data and control lines of OLED using CRO.

But it prints junk values always again power ON / OFF required to solve this scenario.

After power OFF and ON Immediately it will work.

Same scenario as reset key press and release or power ON/ OFF

Kindly guide me how to resolve this

We have one more problem that working good in LCD but in OLED Display will be blank (no data) in the display after some period of time but data received to OLED we checked with voltage level and using CRO also.

time of the data blanking can be changed periodically 1 Minute, 5 Minute or 10 Minute interval.

hi sir,

 thanks for your reply.

I am using NHD - 0420DZW - AB5 OLED and my controller is 32 bit micro controller.

when power OFF and ON Sequence is performed it is working fine.

when reset button is pressed in the controller the data in the OLED gets displayed as junk value.

And also i have one doubt,

when power OFF and ON the display work properly.

for every reset it will print junk characters.

IS THERE ANY COMMAND NEEDED TO GIVEN AFTER RESET OR HAVE TO CONNECT ANY CONNECTION BETWEEN CONTROLLER AND OLED

Dear Sir,

Parallel Mode 4 Bit Interface we are using. It is working fine in Arduino but not able interface with 32 bit microc ontroller.

OLED Found Working sir but i have to send values from the register that i read from analog.

How i can able to give that to OLED Display.

In that only 1st and 3rd line displays data other 2 lines missing. Is there any thing i want to modify from your code example.

Hi Sir,
         Thanks for your reply. Send me if you have any arduino sample code for Serial OLED Display using SPI

Thanks for your reply..

Kindly provide sample code for SPI Interface. And i am modified Jumper settings as per the Specification sheet in your website.

And  I am using arduino for this interface programming.
