OLEDs / Re: OLED Update timing problem
« on: October 26, 2017, 01:04:17 PM »
Kindly provide some solution for the below same

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.

Yes i reinitializing it.

but after power ON it is working.

during reset only junk values presents.

i may think that during power off and on OLED Supply voltage is disconnected and connected and during reset no supply interruption. is that may provide junk characters.

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

Hi,

         i am working with LCD with updating data to LCD in 250 mS Interval is working fine.

but updating data to OLED is not working it will print only junk characters.

Kindly provide solution for the above same.

Thanks in advance.

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.

Dear Sir,

            I trying to interface with NHD - 0420DZW - AB5 with my micro controller but not able to get good results.

kindly provide some sample program for testing.

thanks in advance .

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.

Kindly Send command register  and Data registers to write data to OLED via SPI.

On Your example is not working for me in NHD-0420DZW with Arduino and as well in ATMEGA328p using ATMEL STUDIO.

Kindly Help me on this issue.

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.
