Character LCDs / Re: How to program LCD-0224AZ-FSW-GBW
« Last post by Saurabh_B on October 25, 2017, 08:09:49 AM »
Unfortunately we do not have a guide on how to do this with linux.
However there are plenty of libraries and tools available that can help you drive the display.

I would recommend looking at the following:

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.

Saurabh_B,

I am also having similar issues with NHD-0216CW-AB3 -- tried 2 modules.

Date code is 01 17 NHD_0216CW_AB2.

Are the SHLC, or SHLS signals, from the US2066 controller, available anywhere on the module PCB?

Thanks.

You are probably sending information to the display quite fast for this to happen.
Is it possible for you to insert a delay between each character you write to the display. Also inserting a delay between any commands sent.

Typically i recommend a 600Ás delay between most commands / data writes.
You will need about a 2ms display after sending a clear display or return home command.

After the reset is applied are you reinitializing the display?

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.

What OLED are you using?
Depending on the controller used the timing will be different.

« Last post by Saurabh_B on October 24, 2017, 08:02:25 AM »
Yes, you would be able to solder a 2x8 pin header onto the display.
You will need 2.54mm pitch, or 0.100" pitch pins for this.

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
