Data on OLED Display is getting corrupted over time.

[PD5DJ]

When Using the ATU-10 with FW v1.5.
Display information is getting more and more corrupted over time after power on.

Even on power up, the display most of time shows weird artifacts.

Even when no RF is applied.

I have changed:
#define Delay_I2C Delay_us(100)
in oled_control.c

You can very good see when artifacts start to arrise.
But because of the slower update 100uS vs 25uS, clearing these artifacts upon rewrite of the display clears these better.

Refreshing display content needs some tweaking.

Hi.
Yes, my tuners OLED does it too.
At this moment I guess bad displays from China make trouble because my other device do same thing and I forced to change the display

Hmm ok..

I have some older OLED's i will try and swap them out and let you know the result.

You where right!, replacing the OLED "fixed" this issue.
So the supplied OLED's with the ATU-10 are really bad. hmm

Other question, what is the reason you have set the:
#define Delay_I2C Delay_us(25)
To 25uS?

Hi.
It makes the bus speed about 20 kHZ
