Re: Screen touch interrupts

In short, the setup code is like this: wr32(REG_INT_MASK, 0x00000002); wr32(REG_INT_EN, 0x00000001); Does it seem to be right? depends a bit on the value you have for REG_INT_MASK, if you use our sample code we define it as 0xb0 which means you'd have to use RAM_REG + REG_INT_MASK to get its final ...

Re: Screen shots using EVE (BT815)

We don't have any example code available for it, but the CMD_SNAPSHOT and CMD_SNAPSHOT2 commands from the Eve Programming Guide will be useful for this use case.

Re: HTT HDMI TFT Support Utility

Likely a permission issue imposed by the OS, can you try with sudo ? If that works you'll have to add a udev rule to give users permissions to touch the device : ATTR{idVendor}=="1b3d", ATTR{idProduct}=="14c9", TAG+="uaccess" will likely do it, but i don't have system t...

Re: Linux ASTC encoder

The format is a little different, it requires a specific block order, you can find some details and a conversion script on the bridgetek forums over at

Re: resistance threshold touch value of eve2-70A

I can't easily tell what your code is doing or what the debug output means, best i can do is refer you to our manual calibration example code available here

Re: resistance threshold touch value of eve2-70A

Regardless of the touch calibration matrix, the output of the `REG_TOUCH_RZ` register should be in between 0 and 32767. if you go by the letter of the data sheet you should and it with 0x7fff but I admit I've never seen bits 16-31 being anything other than 0 the fact that you are reading values way ...

The gtt designer is actively requesting elevated privileges, the way the designer communicates with the unit requires this. If you drop us a line at support@matrixorbital.ca we can send you a copy that doesn't request these privileges, however, the automatic deployment functionality will not be avai...

Re: DriverCore SDK

Uhmmz, well this is embarrassing, it seems like IOCTL_GET_DEFAULT_CONTRAST got defined, but didn't get implemented which is why it's failing on you. I'll make a note to get this implemented, but it might be a bit before that'll happen, sorry about that.
