Hello,

I checked touch controller data lines, and its working fine, now i have added the while(EVE_MemRead8(REG_CPURESET) != 0x00) instruction too, and its working fine. But still i don't know the exact reason of sudden disable of touch ::).

Right now, the display and touch are working fine. Thank you for your continuous support.

Regards,
Asma

Hello,

Yes the issue got resolved after adding the while (EVE_MemRead8(REG_CPURESET) != 0x00), but when i was testing the keypad, the touch got disabled again. And, after removing the (EVE_MemRead8(REG_CPURESET) != 0x00), touch got enabled.

I didn't changed anything in my initialization code. Its the same code which i send you through email. Please find the attached copy for the FT813 initialization for your cross check.

And the touch controller present on my Newhaven display is FT5x06 controller.

Thank You,
Asma

Hello,

Thank you for your reply..

Yesterday, i checked it through the code only, then i removed  the while (EVE_MemRead8(REG_CPURESET) != 0x00) from the initialization sequence and run the code and checked the calibration part and the touch got enable.

Few days back i couldn't able to enable the touch but after adding the above instructions, it got enabled. But now, without that instruction it is enabling. What might be the reason for this behavior???

I will check the touch controller with oscilloscope and update on it soon.

Thank,
Asma

Iam using NHD-7.0-800480FT-CSXV-CTP FT813 controller display. It was working fine till yesterday when i was checking the keypad working using cmd_keys, all keys were working fine and touch was enabled too and was working properly. But today when i was checking, it started behaving abrubtly, like the key tag was detecting without any press. Then later i checked with calibration function, then i found out it as it touch is not working.

In one of your blog's topic, i studied that Newhaven display needs extra settings to boot up. Iam referring the code present in the git hub i.e. https://github.com/RudolphRiedel/FT800-FT813 . Is their any need to add any extra settings?? or what might be the issue of its touch getting disable suddenly??

Please suggest the solution.

Thanks,
Asma
