Looking at the chart with fresher eyes, it appears that RTS/CTS can be implemented without using XBAR :
Teensy 4.0
Serial3, CTS Pin 19
Serial5, CTS Pin 35
Teensy 4.1
Serial3, CTS Pin 19
Serial5, CTS Pin 43
Serial8 CTS Pin 50
Am I reading this...
I'm sure this is a well-worn subject to some of you around here, but it's new to me.
If I want to use RTS/CTS handshaking between two Teensy 4.1s, I need to invert the incoming CTS before it gets to the assigned pin?
So it would seem, since...
Thanks for the reply.
It was short ESD spikes that I was thinking of. If the spike gets swamped by the regulator filter, I suppose all would be well.
I need to spend some time looking at industry literature that describes the typical ESD spike...
I found this thread while thinking about this very thing last night.
Say I use BAT54-S packages across a batch of GPIOs, with the high side tied to the 3.3V rail of a Teensy 4.1 .
Looking at the schematic, that probably isn't the best thing to...
