This\nwas enabled by the switch to low impedance bias using an operational\namplifier instead of resister voltage dividers. Also eliminated\nprovision for pin16 CS as the version 4 hardware does not use this.\nThis will obsolete all pre version 4 hardware.\n\nSample rates are increased from 500sppc (sample pairs per cycle) to\nroughly 640 (60hz).\n\nEliminate filtering of low ADC values near the bias voltage to stop\nspurious 1 and 2 watt readings on inactive channels.  With the op-amp\ncircuit, they read zero without filtering.\n\nChanges to phase shift measurement API.  This is an undocumented feature\nused in development.\n\nModify   default configuration for version 4 hardware.\nModify configuration table with various updates.\n\nVarious bug fixes in config app (index.htm)","distinct":true,"url":"https://api.github.com/repos/boblemaire/IoTaWatt/commits/d2e20f0268adbcb93f7107d8fd0f0f5e6c0f105c"},{"sha":"783b6b68ab34e7669495fae44d4401bd03ec73c5","author":{"name":"Bob Lemaire","email":"795a292003e7d149421281a6ff417a3c0f4b8d8d@overeasy.com"},"message":"Add 4.1 schematic\n\nAdd 4.1 schematic.\nRemove old hardware versions.","distinct":true,"url":"https://api.github.com/repos/boblemaire/IoTaWatt/commits/783b6b68ab34e7669495fae44d4401bd03ec73c5"}]}
