Hi,

I've just installed this version but I don't find ft_argb32_t type on selection list of a variable for example. Is it normal?


regards

Hi it's a Matrix Orbital 43A IPS with EVE3 BT815 chip.

Hi,

This doesn't work. I tried another one.
I wrote 0x04 at hidden address 0x3020E4, this reduces signal to 140KHz and that's all.

Hi,

I'd like to disable this output by software because screen emits 20db peak on spectrum analyser on near field with ffc20 ribbon. This is problematic for CE certification.

When I cut AUDIO_L line on FFC20 ribbon on screen side, it's ok! But I need a software solution.

What should I try?

If I disable audio engine (reg_cpureset=4), output is still active.

What in theory could OFF AUDIO_L pin, I see nothing in BT815 datasheet, there is always 30Mhz sinusoidal signal in idle (no sounds played).

Thank you.

Hi,

This seems to be same problem than me!
When font is already inflated in RAM_G, the render crashes sometimes.

Please see link below:

Hi, no I can't.

Fonts and pictures can rarely but randomly be glitched. I've localized and reproduced the cause.
It's in file Esd_GpuAlloc.c. If I change address of an AllocEntries it corrupt font or picture in RAM_G (this is normal, but what is the cause?).
So it can be a pb in the algorithm of esd allocation or maybe ram overwrite in my app.
I've also set safe defragmentation macro added in v4.11 but this increase a lot chances to have glitches.
Safe defragmentation doesn't work for me.
I use also gradient widget which require alloc/dealloc when it is displayed/not displayed.

Hi,

You must use update callback of esd to send orders to the screen.
You can use queues or semaphores to get data in this callback.
To simulate on ESD your GUI you can add buttons connected to slots.

It is a font added to the project. I'm using scroll panel but in a another screen. It's like a scissor would be applied on the font whereas i'm not using this.

As you see in attached, i'm using ESD label in linear layouts.

I have a main screen where font is used. When I slide the screen to the right a new screen that using scroll panel appears from the left, so at a moment font is displayed at the same time as scroll panel.
The slide is not done via scrool widget but with slide animations used by ev demo.

For fonts it's another problem that I must find.

The thing is why draw an element which is out of the screen?
if I draw only the visible part I have not the problem so I use vertex2ii

I have a screen of 480x272 i'm using a picture at x,y,h,w=4,10,36,36.
Screen is sliding of 240 to the left so only x is varying to -236.

Hi,

I'm using ESD and sometimes fonts or ESD_images are truncated when I'm doing slide animations.
I've localized where is the problem:
In file Esd_Render_Bitmap.c:

void Esd_CoDl_Bitmap_Vertex(int16_t x, int16_t y, uint8_t handle, uint16_t cell)
{
   EVE_HalContext *phost = Esd_GetHost();
   if ((EVE_CHIPID >= EVE_FT810) && (x < 0 || y < 0 || x >= 512 || y >= 512))
   {
      EVE_CoDl_vertexFormat(phost, 0);
      EVE_CoDl_bitmapHandle(phost, handle);
      Esd_CoDl_PagedBitmapSource(handle, cell >> 7);
      EVE_CoDl_cell(phost, cell & 0x7F);
      EVE_CoCmd_dl(phost, VERTEX2F(x, y));
     }
   else
   {
      Esd_CoDl_PagedBitmapSource(handle, cell >> 7);
      EVE_CoCmd_dl(phost, VERTEX2II(x, y, handle, cell));
   }
}

When I comment VERTEX2II part of code, bitmap are not truncated, otherwise I loose bottom of the bitmap randomly with slide animations.

How can we explain this? Is something missing in dl commands?

EmulatorProcess runs the emulator and the user code. Any unusual behavior in your code?
It should normally throttle down by itself already when there are no frame changes being rendered.
The process also runs on the lowest priority by default, so it should only have minimal effect on any other processes regardless. The highest usage will be while recompiling the code.

(If you happen to be running giant ASTC animations, that's the only case on the emulator that's not well optimized, and you might see high usage.)

I'm ok with that, I have UI elements that does not use cpu ressource. But I've noticed that widget ESD_MultiGradientRounded use 30% of my CPU. Why?

* please add an option to export (eclipse) source with alternative name for the entry fn, instead of main().

Hi,

In eclipse you can ignore the file where main fonction is used (app_generated.c) from your project then you can duplicate it and create your own in an other folder. Like this, when I export from ESD, I overwrite always the same folder but my custom App_generated.c is safe.

Hi all,

When ESD is running and rendering UI elements, Emulatorprocess.exe is using 100% of the CPU. Can you reduce that? I think your QT main task doesn't use sleep function to authorize idle time for other tasks.
