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-LO...

I recently received a EVE4 7" display: https://www.matrixorbital.com/ftdi-eve/eve-bt817-bt818/eve4x-70g-ips 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 par...

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! 20210302_175054.jpg EVE_cmd_dl(DL_COLOR_RGB | WHITE); EVE_cmd_dl(DL_BEGIN | EVE_BITMAPS); EVE_cmd_setbitmap(MEM_BIGFONT, EVE_COMPRESSED_RGBA_ASTC_8x8_KHR, 224, 384); EVE_cmd_dl(CELL(0)); EVE_cmd_...

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. 20210228_125720.jpg The map file has these values: unified.blob : 0 : 4096 LemonMilkMedium-mLZYV_255_ASTC.glyph : 4096 : 1032192 LemonMilkMedium-mLZ...

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. Howeve...

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_romf...

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 I ...

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 can ...

Good afternoon everyone, I am seeking help in connecting an Eve 3 Display - https://www.matrixorbital.com/ftdi-eve/eve-bt815-bt816/eve3-50a-ips This is a non-touch model with 128 mb of flash. I am trying to connect it to an ESP32 board as per the included photo. I have compiled the https://github.co...
