Hi there,
Good envision, Just like it is.
shunt_low_side_.otii (1.3 MB)
I attach the OTII project with osme measures. I have tested with 50, 100, 200 and 300 Ohm as load. Besides, two records with a voltage meter on the shunt and amperimeter in series with battery.
Battery voltage was 3.3V so current with 100 Ohm it is supposed to be 33 mA and the Voltage drop across the shunt 3.3 mV.
Using las firmware 1.1.2 on OTII

what do you mean with without the 100 Ohm resistor?
Here are also some pictures:
Simple circuit
Real voltage across the shunt:
