SK-TDA4VM: Touch screen implementation in TDA4

Hi xiaogang liu,

No, there isn't any touch screen demo in the SDK.

For the lvds configuration, Is it possible to configure it on A72? or you could add remote service on R5F to configure LVDS and then call this remote service from A72 application.. 

Regards,

Hi Brijesh Jadav:

I can only configure lvds on mcu2_0.

 I can refer the way how sdk configure and control the sensors in chapter 8.12.5 of the follwing guide. Right?

Hi Brijesh Jadav:

In the remote service for sensors, A72 takes the initiative to configure and control sensors. But for touch screen scene, users press the screen, mcu2_0 should takes the initiative to transmit the postion of pressed points to A72. A72 changes the role from sender to receiver. How to user remote service API now?

Yes, this is correct.

You could even implement remote service on the A72 and R5F can call this remote served on A72. This is possible. But please note this requires A72 application to be running, because A72 service can start only after application starts running..

Thank you very much!
