SUCCESS!!!!! As I indicated above, I'm unable to use current Teensyduino, as the NativeEthernet doesn't work on my system. Perhaps I'll move over to QEthernet and get it working. To make the new functions work in Teensyduino 1.5.3, I copied...

I can't explain it, but if I use newer builds than Arduino 1.8.3 and Teensyduino 1.53, my writes to Teensy 4.x fails on my computer. I use an HPZ640 with Windows 10 22H2. I suppose I could install 1.59 on a bogus computer and copy the entire...

I'm using Teensyduino 1.53, as it works best on my computer.

Thank you KurtE. Is the library ready for me to test? Do you have a link to download? Is the library called "Serial", or is it more specific to the UART ports? Do I just replace the installed folder with the new one? I use a slightly older...

I see KurtE and Paul S. are in talks on an RTS inversion. Do I understand that you are making a modification to the official Teensy serial library, or this is a custom library I need to install into the existing libraries? I'm not EE, so do...

Thanks gentlemen (or GentleCats). KurtE's idea is far too practical. It defies that natural law of Entropy!

Thanks PaulS!

I have two Teensy 4.1 processors on a circuit board that have parallel digital i/o connections. The source Teensy acts as output, and the destination Teensy acts as input. I have used up all digital pins on the destination Teensy, and I am...

Thank you. Question for jmarsh: Does the inverter input from RTS and output to CTS. or vise versa?

Thank you 'dundakitty' for your informed response. It's unimaginable that a major chip manufacturer could make such an overt design error. Unfortunately, the Serial3 dedicated pins are unavailable to me, as I could not main sketch backwards...

This subject has been covered in prior years, but I'm not clear on the solution. Please forgive the redundancy. I have a circuit board controlled by a Teensy 4.1, and a daughter card with Teensy 4.0. I need them to talk to each other. I have...
