EVE3x-70A display parameters

I'm trying to get an EVE3x-70A display working and looking at the Bridgetek PIC24 sample code. The sample code is not specific to this display. One part of the start up code sets the display parameters as follows. I know the display is 800x480 but the rest of the parameters are very display dependen...

Re: EVE3x-70A electrical connection documentation

After receiving documentation, it is possible to route the 3.3V to J6.1 by moving R11 to R14. No need to cut the trace and use the mod wire. Just might be a manufacturing BOM issue on the 5-15V power input option.

Re: EVE3x-70A electrical connection documentation

talked with support and they recommended the pin out is documented in the EVE3x-43A display documents tab by downloading the user manual EVE3x-43-Manual.pdf. The EVE3x display is found at https://www.matrixorbital.com/eve3x-43a-ips. Section 4.1 documents the pin out of the 20 pin FFC flat cable and ...

Re: EVE3x-70A electrical connection documentation

now I have the EVE3x-70A on my bench with the 5-15V power option. I'm using a 15V power supply. I see the 20 pin connector with reference designator J6. The connector signals are labeled but somewhat misleading. I'm not sure where the ~RST signal goes. I had assumed it would connect to pin 12 (PD_N)...

Re: EVE3x-70A electrical connection documentation

I took a closer look at the Bridgetek BT-815 datasheet and was able to get the digital signal levels from there. I'm assuming it is a pass thru from the EVE3x-70A interface board header to the BT-815 pins. There was a sample circuit documented in the datasheet but it shows an 8x2 16 pin header so I'...

EVE3x-70A electrical connection documentation

I'm a newbie on this forum but a consultant with lots of experience in embedded system design. I'm looking for something super simple, which I'm sure exists, but I just can't seem to find it on the Matrix Orbital Web Site. I'm designing an interface cable from my custom embedded system PCB to the EV...
