Hi all, Any reason why the default lm80 configuration makes in5 and in6 dependant on in0? compute in5 (160/35.7)*(@ - in0) + @, (@ + in0 * 160/35.7)/ (1 + 160/35.7) compute in6 (36/16.2)*(@ - in0) + @, (@ + in0 * 36/16.2) / (1 + 36/16.2) I guess that the idea is that negative voltages depend on a reference voltage, which would be the same value as in0? In this case, all other chips that use a reference voltage for negative values should do the same, but don't. At any rate, shouldn't only the register -> real value conversion do that? The other way is used to set limits, and the limits shouldn't depend on measured values. Thanks. NB: Try "compute in0 @ + in0, @ - in0" for some fun (doesn't last long though). -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
