I need to monitor some temperature sensors, some voltage levels and current values(total 30 values) once a second.
I will use two UCD90160 devices. Programming will be done by PC GUI tool just one time while checking board. MCU will read VMON values over i2c once a second while running time.
1> Guideline for schematic
Is there any check point for multi UCD90160s and multi master(PC GUI and MCU)?
I need to select one between PC GUI and MCU without modification PCB.
2> i2c
I want to read values over i2c because I don't have any experience in PMBUS.
Is there any register or control pin to select i2c or PMBUS?
How to set normal i2c by MCU?
