I'm not sure what the issue was before but the display is now working fine with the above parameters.

I received assistance from Matrix Oribital support and I wanted to share it with others in case it may be helpful.

The connector in the bottom left corner of the board is a MATE-N-LOK connector. The attached photo shows its polarity.

BLVDD VCC (Pins 17 and 18),VCC (Pins 1 and 16), and VCC (MATE-N ...

I recently received a EVE4 7" display:

I have previously worked with an EVE3 5" display connected to an ESP32 micro-controller. The 5" was working well but when I tried to replicate the connections and code (with parameters ...

For the EVE4x-70G-IPS display, I have the 5-15 VDC option for the backlight. I am assuming that this is the two prong connector that is located in the lower left of the board in the attached photo. I wanted to see how to identify the polarity for the connection and also to know if this is a standard ...

I attempted to replicate your example and hey, at least I got a zero and half of a number 1 working, ha!

With your help, I was able to create a 255 size font (just numbers, no other characters) with the Eve Asset Builder and get it uploaded to the display.

The map file has these values:
unified.blob : 0 : 4096
LemonMilkMedium-mLZYV_255_ASTC.glyph : 4096 : 1032192
LemonMilkMedium ...

After I wrote that last post to you, I downloaded the EVE Asset Builder and tried to create a font myself. I was able to use the font generator to create a glyph and xfont with a limited character set (0123456789), turn that into a bin, and then convert that into hex with the BIN2C converter ...

Thank you again, immensely helpful! I am trying to do things one small step at a time so I can learn what each change equates to on the display.

I started by adding:
//EVE_cmd_romfont(16,32); //First three lines commented out
//EVE_cmd_romfont(17,33); //First three lines commented out
//EVE_cmd ...

Thank you so much for the quick and helpful reply!

I've made another attempt to get the Weather Demo working but still have init issues.

I have two more questions. For your example Rudolph, the task watchdog is triggered every 5 seconds, is this normal behavior? All seems to be displaying well so ...

Using Rudolph's code I got it to work!

I had to change the #define TEST_UTF8 from a 1 to a 0 under tft.c and the display came to life!

I would still like to be able to use the original Matrix Orbital example to connect to the display so I would like to see if anyone has a suggestion as to how I ...
