USB2VGA adapters are capable of displaying up to 1280x1024@32bpp with good quality

Contents

• sisusb.o - Kernel driver, a 2.4 kernel version of Thomas Winischhofer's driver
• S71sisusb - Shell script to load the driver and create the necessary device
• sisbit - Userland program to display images
• test.ppm - Image in case you have nothing at hand

Attach the device after booting up.

My attempts to get a desktop system working are less successful so far. What I did get to work (after writing my own display and keyboard drivers) is the Nano-X/Microwindows system, which, however is rather limited.

DougBarry:
Have utilised above code in an experimental Digital Photo Frame project using a slug. Very early stages, but have slideshows kind of working.
Many thanks to Helmut Dersch!

SlugOS/Be 3.10 beta

I have built Thomas Winischhofer's sisusbvga driver for the 2.6 kernel in 3.10 beta and confirmed it as working using Helmut Dersch's sisbit utility referenced above. I have also applied a one-line patch to make the driver work with the adaptor I have.

The binary driver is available here: http://www.markshinn.co.uk/sisusbvga/sisudbvga.ko

To at least vaguely comply with the GPL, here is the patch I put on the vanilla kernel (2.6.16.6):

I copied the module into /lib/modules/2.6.16/kernel/drivers/usb/misc/sisusbvga/ and the called insmod on it. I now also have patches to modules.usbmap, modules.alias and modules.dep that allow the module to be autoloaded. My intention is to revisit this page in the near future to provide these patches and any other details that may be useful. If I haven't done this yet (and you'd find this information useful) please kick me: dev@markshinn.co.uk
