TMS320F28335: GPIO60, GPIO61, GPIO62

Choi Sion
Prodigy 10 points
Part Number: TMS320F28335


I connect optical switch named OPB821S3Z at GPIO60, GPIO61, GPIO62.

They are operate 5Vcc.

They are programmed if their value is 1 then high, on the other hand value is 0 then low.

I want to know when the voltage is recognized as 1 and 0

    Hello Choi,

    Are you asking what needs to be driven to the F2833x device's pins or what the F2833x can drive with GPIO? For  the former you can refer to the Electrical Characteristics table in the device datasheet:

    For the latter, the device I/O is dictated by the device supply voltage, which here is ~3.3V for high and ~0V for low.
