@byron Yes. I'd agree with you, if it took the two and a half hours to get to the undefined state. However, as seen below, it would have to complete t...

FAHC: 2 Hours, 28 Minutes, 34.206 Seconds 👍

@starnovice Yep. I agree. but only from a position of partial ignorance. I've posted to the Arduino forum, and am hoping for clarification.

There seems to be a lot of problems with loops posted on the Arduino Forum, but nothing that seems to match my issue. I continue to hunt. Oh and by ...

Once my 32 bit timing test completes, I'll run a build in verbose and see if there are any clues.

Thanks @sysguru, Just goes to show, there's always something to be learned. It's one of the reasons I'm in the forum 👍

Farah A closer look at the picture of the male connector, makes this a little more difficult. you'll see in the image below that the similar connector...

@pugwash Phil may be right. I read through a couple of posts and it seems that, although both have I2C interfaces, there is little support for running...

I found some SPI libraries on my Arduino IDE. Go into your Library Manager and search for ESP32DMASPI and for TsyDMASPI. Now I may see them because I...

Found this on SPI:

Shot in the dark here but... CAN BUS? Teensy has it built-in, and there are modules available that may work for the ESPs.

Have you looked into SPI? I am working on a multi-processor robot, utilizing a Raspberry Pi and three Arduino Nanos. I just got SPI comms running last...

@fhaddad Glad to hear everything worked out for you.

@fhaddad No problem. I am just interested in the outcome.
