I am using arduino Uno for developing my project. There are totally 24 analog hall sensor out put,1 temprature ananlog output, 1 Rshunt voltgae measurement. There are totally 26 Analog sensor.I am distributing 24 analog channel in 8:1 analog multiplxer usingAnalog Multiplexer; Where it used totally 3 analog ,1 temprature,1 voltage sesnor.
Now @ digital side i need
3 For selecting 8:1 Multiplexer 1 for error status 1 for Blink led 1 for SPD status 1 for disconnector status 2 for MODBUS communication 2 for serial communication 8 Pins for selecting Device ID using DIP Switch totally i need 19~20Pins. SO i need Method of reducing it. Please look my schematic attached If any alternation i can do here let me Know.And my question here is this method correct , Switch i represented here is dip Switch followed by 1k resistor.
I wanted to How can i configure device ID 255 No,
