Hello,

No bother at all, thank you for sharing your solution.

Hello, thank you for your response.

Well don't I feel like an idiot .  I tried using the Windows Anton font to make sure it wasn't something with the font I changed and that's when I saw it.  I'm setting the font to, 13 but I then use a system font, 31.

TFT_qspi_dl_cmd(COLOR_RGB(0, 25, 0));
TFT_qspi_cmd_setfont2(13, MEM_FONT_ANTON_34, 0);

char buf[32];
snprintf(buf, sizeof buf, "%.1f Psi", pressure);
TFT_qspi_cmd_text(75, 60, 13, EVE_OPT_CENTERY, buf);
When I set the correct font to use, 13, the whole display crashes.  I'll have to verify that my set font code is correct cause it doesn't seem to be working, ugh.

Apologies for wasting your time.

Kindest regards.

Hello,

Could we check which model of EVE chip you are using with your font?

Also, which EAB conversion settings and which application SetFont2 code were you using to set up your font?

Hello,

I modified a font, Reglo-Bold, adding a "degree" symbol but I'm unable to actually display it.  For some reason, depending on how I try to display it, it'll show up as a '0'.  I'm confident the symbol is there and in the correct position.  I viewed the images created by EVE Asset Builder v2.10.2 and it's there.

I've tried a bunch of different ways to display it:

snprintf(buf, sizeof buf, "%d " "\u00B0" "   F", temperature);
TFT_qspi_cmd_text(75, 120, 31, EVE_OPT_CENTERY, buf);

I'm not really sure what I'm doing wrong or maybe something like this isn't possible?

Any insight would be greatly appreciated.

Kindest regards.

Ok, this could answer to this topic: http://www.brtcommunity.com/index.php?topic=428.msg2117#msg2117

I've seen that issue is resolved in new version of ESD in Esd_Render function.

Thanks, so it was the "Display list instruction overfetch".
I even already had BRT_TN_005_BT81x_Errata_Technical_Note.pdf.

I just was not looking under https://brtchip.com/document/technical-notes/ , maybe add (Errata) to that one as well?

Oh, and another small thing, "Programming and User Guides" is sorted by date, newest on top, could that perhaps be done on "IC Data Sheets" and "Application Notes" as well?

Hello,

Details of the Errata can be found in the following Technical notes:

This seems important... so I am boosting this post.

Introduction

Adding a graphical touch HMI (Human Machine Interface) to a product is a great way to enhance the user experience. But the benefits go way beyond this: It adds flexibility to accommodate new features (both now and in future), helps overcome obsolescence of traditional controls, and enables a family of products to share a common HMI platform with strong brand visibility, while remaining easily customizable and supporting multiple languages.

Thanks to the innovative Embedded Video Engine (EVE) from Bridgetek, designing or updating products with a graphical touch display interface is fast and easy to do, even when the engineers have no prior experience with touch screen graphical HMIs. The graphical display, touch and even audio can be added to the existing MCU over SPI or Quad-SPI (QSPI). Along with extensive design software tools and examples, this solution ensures the product can benefit from the advantages in a short timescale.
