I recently acquired a Giga R1 and I wanted to ensure that I was not exceeding maximum input voltages from my motor encoders.
I looked at Table 4, page 7/22 of the Datasheet (ABX00063-datasheet.pdf). I reproduced the relevant line below:
VDD Input high-level voltage
Min = 0.7*VDD
Max = VDD V
I found this confusing as VDD is defined in terms of itself. There is a note below that says:
Note: VDD controls the logic level and is connected to the 3.3V power rail. VAREF is for the analogue logic.
So I assume this means that the range is:
Min = 0.0 to 0.73.3 or 0.0 to 2.31 V
Max = 0.73.3 to 3.3 V or 2.31 to 3.3 V
From this I should connect the Vcc for the encoders to the 3.3 V output on the Arduino.
Can someone let me know if I'm interpreting this correctly, please?
