Hi Ben, Hi Jorgen
I'm using the display manager (without a touchscreen). It works very well.
I had the opposite problem from Jorgen: the values on the display were updating too frequently.
So I set it to update the display only after 50 samples, and only for the values that have changed.
I have one more request for a voltmeter: larger characters, if possible:
add size 48 72 96 120 144

Hi Jorgen
Thank you,
I found the setting. It's the fonts you can create on the display.
So I added some new fonts
Once everything is working, I can post my program

I'll see if I can do it tonight for you. Currently on a roll with ESP32 Zigbee but as soon as that's complete I'll get on it.

Hi Jorgen,
I've updated my first post on this topic with a second video,
hopefully which is helpful in overcoming the problem you're having.

Hi Ben!
Thank you, I'm really honored

I've tried almost everything, but I never figured this one out. I'll implement it in my projects, and testing, you' hear from me.
Very nice and detailed video, make sense.
Jorgen

Hi Ben, Hi Jorgen
I've integrated the display manager into my program. It's easy to do.
I've tested the scenes in the simulation and on the display, and they work both very well.
In the scenes, you can see the grid, which is practical.
Simulation has no Bluetooth adress and project file name.
The difference in the blue color is due to my camera; on the display, it's a perfect blue.
The display only shows the measured value when it changes.
But when it does change, you see the number build up from left to right.
I use SPI with 80Mhz
A question: On another display, I was able to enable “Queue Fast Pixels” and the problem went away.
Is it possible to add “Queue Fast Pixels” to the gLCD_ST7789V ?

Hi Stefan,
It looks doable, I'll see if I can get this in for you today.
Hmm on further investigation the properties are already there in the SPI Settings section. Do you have these set to Yes?

Hi Ben
OK, that was already set to “Yes.” I didn't notice that.
The only difference for me is the prescale.
Do I need to increase the pixel queue?
or what can I do?
