With autoresize width it does'nt work.

Discussion - EVE / Autoresize label width

I'd like to resize the width of my labels function of its content in a linear layout to avoid spare distance between labels.
But I saw that autoresize height works great but width is not working. How can I do that?

Hi,

In my screen I have multiple variables which are connected to text property of ESD labels. When render is called, text is refreshed each time, even if variable value doesn't change with spi transferts useless.
How to avoid this?

Hi , Thanks for this answer.

I use Update callback which is called here:
   ec->DeltaMs = ms - ec->Millis;
   ec->Millis = ms;
   Esd_GpuAlloc_Update(Esd_GAlloc); // Run GC
   Esd_TouchTag_Update(NULL); // Update touch
   if (ec->Update)
      ec->Update(ec->UserContext);<--callback

An other question I have is how much time can I allocate to scheduler for other thread execute (by tx thread sleep(time) instruction) without lock screen render? If I consider thread UI is the highest priority.

Is it would be a message queue like in guix?

When I export ESD project to eclipse with an image in flash I have a __flash.bin of 4MB and __flash.map files created in data folder. How to transfert these files to spi flash W25Q32 of BT815 from my little MCU flash of 1MB?

Hi,

I'd like to display a loading page with progressbar during inflating or loading of image and fonts...
How to make this?
If I load an image in SPI flash of EVE from MCU flash, and I restart esd application, how can I detect that image is already in eve flash to not reload it?

This was resolved by doubling lines of 3V3 and GND on FFC cable by short cut R9 and R10 on matrix orbital board...

Hi,

We're migrating our monothread project on simple LCD display to EVE display.

I use 2 threads: one for display with EVE ESD project UI and an other for our own library. This library must send events info, data structures, event for displaying and synchronysing with UI thread.

For example our library must send an event to change of EVE page or to display or not some widgets.

There is no examples of this implementation/architecture.
How can I handle this easilly?

Regards

No need to give you the project.
I think there is a hardware problem that cause a software problem on coprocessor fifo.

If I make a contact on SCK of spi with my oscilloscope probe I can lock fifo easily. Probe has an effect of antenna that degrades the SCK signal.

On the other hand if I wires screen without the ribbon cable FFC (standard wires)I have no problems.

Recovery procedure are already handled by ESD exclipse export. The main problem here is that coprocessor fifo is in an instable state even if we use recovery procedure or reset  the chip (powercycle function) without unplug power. We must add serial and pull up resistors  to adapt impedance  of SPI bus lines like in Ft800 datasheet suggest.

I think there is a case where we can lock FIFO memory and today there is no way to unlock it even in datasheet. You must reproduce this problem and correct it.

When screen is black (or white, it depends) coprocessor fifo space is not released, it makes a resetcoprocessor, after cmdb_space =4092, I make 2 writes and cmdb_space=4084 but is not released and so on!
I think coprocessor is locked. How to unlock it without switch off/on power?

Hi,

I 've made a screen with ontly 3 labels rendered in the normal loop of ESD4.10 exported eclipse project on a renesas synergy MCU.
I've enabled  _DEBUG preprocessor.
It can display 10 minutes without errors and suddenly
I encounter many display glitches and hanging randomly:
- "illegal option in cmd_text"
- bad characters
- screen becomes black but program runs normally in background and i'm unable to unlock it since there is no error detected. I must unplug power to unlock it.

It's like BT815 was in a normal state but not the screen...
Modify SPI bitrate changes nothing.

Do you know what the cause?

ok I see... text is unicode but not in text field of ESDlabel!
You must write "\xc3\xf2..." in C code to support special characters.

Thanks for this reply. I'll try this soon.
