Most of them are not using Linux > or only use it as a secondary OS...expecting me :) I just checked and there is no way to differenciate between a MAX6657 and a MAX6658 anyway (nor a MAX6659, BTW), at least not according to the datasheet. So if we support one we have the others for free. > If you do NOT want to include support for this chip (maybe because it > may cause misdetection problems or something like that) just tell me - No, there's no problem adding support. The "misdetection problems" are inherent to I2C and if it justifies (IMHO) that we don't support chips that are not used, it is definitely not a reason for not supporting a chip once someone requests such support. > I did not buy the chip until now. But if you are going to support it, > I will buy it, because it is said to be very precise. FWIW, Analog Devices ADM1032 is as precise as the MAX6657, at least from comparing the datasheets. The National Semiconductor LM90 has a lower accuracy. So if you can get you hands on an ADM1032, you could go with that as well. But if you end up with a Maxim chip, I promise I'll add support for it. > I wanted to buy the chip yesterday somewhere on the internet, but I > did not find any site where it is sold...do you know a store on the > internet where I may buy it? (I just thought so because you are "in > touch with this scene" ;) ) Usually, either we have the chip in a piece of hardware we happen to own, or the manufacturers send evaluation boards for free. We do not buy anything. If you just need one chip, you can take you chance on the manufacturer's site itself. They usually send free samples for people to experiment on (or so I heard). They are used to sell them by 1000 to manufacturers, so I guess they don't really care about one or two samples. > Thanks again for your efforts!
