Re: [Openchrome-devel] Fix vt1625 output sensing

2012-11-26 Thread Harry de Boer
Hi, I have made some progress: - I updated the output sensing patch to support the VT1625S. The power register has the same layout as the status register. A 0 is always for the DACs that are not present, so writing all 1-bits and reading back the register results in a mask of which DACs are a

Hi Xavier, thanks for the pointers, I did not know there were two variants. I have the VT1625 variant without the 'S' (that is good, it means we can test both). The VT1625S seems to have status bits 4 and 5 always read 0 which on the VT1625 would mean an S-Video cable is connected ( I assume
