This is only a product brief, I was referring to the complete datasheet for the device. Not sure if it can be downloaded publicly, I think I got that one from our technical contacts at Fintek. > Please let me know if I can do anything else. > Especially if there is anything I can do to provide you with hardware > specific data > to support development of lm-sensors (I actually don't know if there is > support missing for any of the hardware parts) There is definitely support missing for many parts, but the hard part is to get the datasheets and then write and review the driver code. For board configurations, you can definitely help. If you can contribute configuration files for all boards you have, this would be welcome. -- Jean Delvare http://khali.linux-fr.org/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
