OLED Update timing problem

<< < (2/3) > >>

Saurabh_B:
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?

nathanbabu:
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:
When you reset the MCU do you know if it sends any random information out of the port that's connected to the LCD?

nathanbabu:
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.

nathanbabu:
Kindly provide some solution for the below same
