My software for touchscreen in the board MB1260 D-01 works, but the same software for the revised board MB1260-F723E-D03 does not work! Any idea?

Hello

I have heard about some update of the touchscreen controler chip.

so the driver needs to be changed accordingly.

ft6x06 => ft3x67

I don't think it is present in the F7 software package (yet?).

But I know it is in latest L4 package... STM32Cube_FW_L4_V1.17.1\Drivers\BSP\Components

Please check the attached file.

So, will the replacing of the driver in the software help with the upgrade? Thanks
