Dear developers, let me give you a short note about my project. I want to make an old stage light equipment (24x dimmed lights) programmable. It's a highschool theatre group, so the budget is very low. I don't want to use DMX. I've built up a i2c controller with a PCF8584 wired to the printerport, but mixed up the clock capabilities with another chip, so have to add an oszillator. The kernel patching compilation of the cvs i2c under debian with some patches was trike and took me some compile time. So i've hacked kernel/Module.mk to build and install i2c-pcf-epp.o, as usual. Now I can mod the sources and the compilation of the modules takes 5 seconds. I've found some problems and critical circumstances in i2c-pcf-epp and fixed the irq freeing in case of failed modprobe. Another point is a wrong adress in a debug output (see ticket). Can I contribute this and following improvements (i hope so) to your code/cvs? I'm not used to cvs, so give me an hint. thanks for your time Michael Weber --- Michael Weber MMC StartUP GbR email: michael at mmc-startup.com mobil: +49 171 5235201
