Hi Vitaliy, I've migrated from the 4.3 to the 5" display, but both are the 480 x 272 pixels formats. As I created the SW, I did try to keep in mind the larger display with the 800 x 480 pixel layout, but I had no way to test.

If your work is for the 7" w/Cap Touch display (for example), I would try to help you figure out any needed changes to the driver.

For the capacitive touch screen, on the other hand, you might be more on your own. I mention on the Components - RA8875 page that I don't have any support for that simply due to the fact that for my project needs I could not give up the extra pins needed for the I2C interface to support the cap-sense controller (so I didn't buy one). I tried searching the mbed site but couldn't find any work of others that might fill that gap.

2017 Update: This is an old post, but in the summer of 2016 I picked up a 7" display, 800x480, and with the capacitive touch panel. I've integrated the touch driver into the base code, so that it [more or less] transparently supports either the resistive or the capacitive. Of course, only the CAP sense version handles multi-touch.

Thanks for the answer, I'll continue to investigate. I display ER-TFTM070-5 http://www.buydisplay.com/default/7-inch-lcd-module-capacitive-touch-screen-panel-i2c-spi-serial, configuration 4-wire SPI + Resistive Touch Screen.
