AD7606 / TWO EMG / TWO ICM-42688-P — COMPLETE SYSTEM CONTEXT
Green/orange: executed digital interfaces Purple: analog chain illustration
Red/black: ideal power context Gray: SDMMC replaced by RAM disk Blue: logical UDP link
3.3 V digital · 3.0 V analog · 5 V ADC · 1.5 V midpoint
Battery and USB states are injected by the fixture.
Power, charging, USB transport and runtime are NOT simulated.
EMG1 / EMG2
No electrodes or person.
1 V / 2 V known inputs are
generated inside ADC model.
Analog response: separate ngspice.
AD7606 · ±5 V · OS=0
CVA/CVB together · all 8 words read
Only EMG1/2 exported. Mode straps
and unused inputs: see lab guide.
