Using DS9490 to set DS18B20 resolution
7 April, 2011 - 15:56
Just an update to say I have managed to set the resolution on my network of DS18B20 sensors using a DS9490 USB adaptor and the one wire viewer from Maxim.
The DS18B20 has 9,10,11,and 12 bit resolution, set using bits 5 & 6 in the onboard Configuration Register - the power up default is 12 bit, but can be re set in the free windows appz from Maxim.
My network now seem to retain these setings when its re connected to the HAH.
Regards
Harry
