Hello.
I'm using a modified SK-S7G2 board with SDRAM and a 800x480 TFT with the same resistive touch panel interface as the original board. I have two versions of a project that displays images and returns touch events, one for the original board and another for the modified one. My problem is that only the first version returns touch events (but in this case there is not image at all because of the incompatibility, of course). When I flash the modified project, the 800x480 images are fine but when I touch the screen only the first IRQ9 is generated and the firmware does not consume it. I'm trying to find where the external IRQ9 is enabled but I'm getting lost in the framework source. I have all the touch panel settings identical in both versions of my project, and the P0.04 and P6.09 pins set also identically. What can I check, please, in order to get the touch panel interrupts serviced?
Thanks in advance.
