Here's a summary of the GPIO results so far. The only trend I see so far, is that perhaps bit 12 (0x1000) indicates the presence of a radio. I don't see any bit that Silvano, Shaun, and David all have in common (besides 0x30000) to indicate the presence of IR. Speaking of which, do we know how the IR module is connected to the FV card? Is it on I2C, gpio, or somewhere else? Can everyone fill in this list with with 2k v. 3k radio v. no radio IR v. no IR EEPROM v. no EEPROM Cheers, Shaun GPIO Results for FlyVIDEO cards -------------------- Philip Gladstone ? 1,3,5 NTSC 2k (?)
