The following image shows 4 signals in the circuit. The ground (0 volt) levels for the red, blue and green traces are all set coincidently where the blue Ch3 flag is located, 1 division from the bottom of the screen (see scale in white at right).
The gain for the yellow trace (Ch 4, top) is set to 2 v/div and it’s ground level is located 3 divisions from the top of the screen (see scale in yellow).
The power supply voltage for the motor is 4.3 volts. Each of these signals appears at one of the GPIO pins.
1. Green
2. Red
3. ----
4. 0.2 amps
5. Blue
6. Yellow
7. 310 amps
8. 2 amps
9. yes
10. true
11. -----
12. it decreases
13. -----
14. it allows the code to read the peak current

Because the Nscope will clip signals above 5 volts (and in fact the trace may disappear), the power supply voltage for the motor is 4.3 volts to stay below this limit.
Each of these signals appears at one of the PSoC GPIO pins.
The signals shown above come from the following PSoC circuit
If the gain of the PGA were increased, what would be the effect of the motor current for a given DAC value?
There would be less average current
