require code for designing on EVE2-70A

[madhusudan.jadhav]

Hi there,
I am using matrix orbital EVE2-70A with resistive touch screen display for my industrial projects. I am using infineon xmc4500 relax kit. Please send me the project code which has used this display. I will convert it in my project. Thank you.

Hi Madhusudan.Jadhav,

You can find all of our EVE2 application notes on our Matrix Orbital website, and our GitHub page.

https://www.matrixorbital.com/app/app-eve-series
https://github.com/MatrixOrbital

You should be able to take this code and adapt it for your microcontroller. You will also find a C based EVE2 Library that you can port over on our GitHub page.

Cheers,
Daniel

Hi,
thank you for given link. I did the program as per manual and eve knob. but display isnot going on. please help.

Hi Madhusudan.Jadhav,

Have you modified the EVE Know code at all to properly interface with your Infineon processor?

The EVE Knob Example was designed to be used with an Arduino, so modifications may need to be made in order for it to work properly with your host.

Cheers,

Hi there,
I have ported my infineon codes. spi writes the data. but cannot read from lcd. Also power light is red. After Host command i tried to read the REG_ID but the value always comes 0x00. Also I am not using interrupt.

Hi Madhusudan.Jadhav,

So you are not able to read '7C' from the FT81X during startup?

The FT81X does require some time to start up. Could you try implementing a short delay at the beginning of your code to allow the EVE to boot properly? I'd say you start with 1000mS to start with. Once you have confirmed you can read from the display, you can reduce the startup delay.

Cheers,
Daniel

HI,

As I am using Matrix orbital EVE2-70A TPR module
I did the following wiring
1) pin no.1 3.3v, pin no.16 3.3v, pin no.17,18 all are shorted to 3.3 v from mcu board.
2) Pin no.2 GND, Pin no. 15 GND, Pin no. 19,20 all are shorted to GND from mcu board
3) int pin is shorted to GND of mcu board through 4.7 kohm.
is this connection is correct?

[Daniel Divino]

Hi Madhusudan.Jadhav,

Your connections are correct. Are you still having difficulties communicating with the display?

Cheers,
Daniel

I am able to read 7c from reg id. But backlight isnot coming. Also i am reading reset register it is giving output 12.

[Daniel Divino]

Hi Madhusudan.jadhav,

What are you trying to draw on the screen? Could you provide a snippet of your code?

Cheers,
Daniel

Hi there,
I am using eve2-70-TPR. I am getting reg-Id 7c but cpu reset I am getting 224. and display isnot coming on

[Daniel Divino]

Hi Madhausen,

I took a quick look at your startup code. Please note, you don't need to write anything to REG_CPURESET prior to reading the register.

All you'll need to do is perform a rd8(REG_RESET) and read what is in the Reset Register.

Cheers,
Daniel

[madhusudan.jadhav]

Hi Daniel,
No I amnot written it. Also backlight isnot coming. is this the problem? i have given 3.3 v external supply to all supply pins of display. And GND is common for supply source and mcu card. Int is grounded through 4.7 kohm resistor. If you can see I defined the CLKEXT and frequency 36M. Please suggest where may I wrong.
