SainSmart 7inch touchscreen

Hi all, I have bought the SainSmart touchscreen http://www.sainsmart.com/raspberry-pi/r ... a-2av.html but it doesn't works on Windows IoT.

The touchscreen use this ISB controller http://pdf1.alldatasheet.com/datasheet- ... 3723C.html.

There is a way to make things works?

In alternative, where can I start to write a WDF driver myself?

Thanks

Well it is not listed on the compatible hardware listing:

https://developer.microsoft.com/en-us/w ... rfaces.htm

Therefore you will need to write a Universal Driver:

If you can navigate around the MS Website there is a wealth of information, as well as the Forum here:

Try change config.txt. Clear old txt and add this :

Code: Select all

gpu_mem=32                  # set ARM to 480Mb DRAM, VC to 32Mb DRAM
framebuffer_ignore_alpha=1  # Ignore the alpha channel for Windows.
framebuffer_swap=1          # Set the frame buffer to be Windows BGR compatible.
disable_overscan=1          # Disable overscan
init_uart_clock=16000000    # Set UART clock to 16Mhz

# set current over USB to 1.2A
max_usb_current=1

# overscan to adjust image position
overscan_left=0
overscan_right=0
overscan_top=0
overscan_bottom=0

# HDMI config
hdmi_drive=1
hdmi_ignore_edid=0xa5000080
hdmi_group=2
hdmi_mode=87

# 800x600 display
hdmi_cvt=800 600 60 3 0 0 0
