    Looks like i may need to switch to a MAX3232 instead of a MAX232. The MAX3232 is 3.3v I/O. Can someone confirm?

    T4 Hardware Serial Voltage Questions

    I want to communicate with my Teensy 4.0 via serial from the com port of my computer. I looked at the T3.6 documentation and saw the use of a MAX232 chip to deal with +-12v to TTL level...

    I should also mention that I've powered the chips from an alternate 5v power supply (with a 3.3v regulator for the 3.3v parts). If I want to power the teensy from this power supply, I just cut the...

    So, quick update. The MCD3486 seems to work pretty well. Paired this with a CD74HC4050E level shifter to convert to 3.3v signals. So far no random noise issues with the motor energized.

    After some more research it looks like i'm going to try using an MC3486N RS-422 line receiver. From my understanding it should take the A, /A, B, /B, and Z, /Z signals then do the differential...

    Here is the encoder with relevant wire connections:

    Reeson Optical Linear Encoder

    I am currently using it with the TTL wiring but I'm assuming I will have to move to RS-422. The...
  7. T4 w/ Encoder library differential signal question.

    Hello all.

    I recently purchased a Teensy 4.0 with the intent to use it with Paul's encoder library to track the position of an optical linear encoder. This seems to work really well while...
