PiTFT and another SPI device

I'm puttng together a project that will use PiTFT display [1] and,among other things I want to connect nRF8001 (Bluetooth Low Energy) [2]. Other sensors (GPS, altimeter, temperature) will be connected using UART or I2C so I hope there won't be any collisions. PiTFT uses: hardware SPI pins (SCK, MOSI...

PiTFT brightness regulation

Is there a way of software dimming PiTFT [1]?

I don't need much, let's say 2 or 3 settings like 25%, 50%, 75% would be enough.

Would switching the backlight from kernel level with some 200-300 Hz frequency work?

Re: HSD070I651 7" display and driver board

The image quality is not great. It's probably OK for movies or images, but definitely not for text.
I have the whole working set for sale (screen + driver) as I decided to play with PiTFT which seems to be much better, but obviously way smaller.

Re: HSD070I651 7" display and driver board

Please check the photo showing the back of the board (open link and zoom in) or check the board itself - it's all there.[12V, AV1, GND, AV2, GND, BACK]

The red cable has a plug that is too wide (3/4 pins) and can fit in 2 positions, but that's for the button panel.

Let me know if you need more help.
