Hi - in that link it is the second circuit - with a different opt-isolator

Hi @Tombot7 - the Teensy 4 pins are not 5v tolerant, it looks like you are driving them to 5v which will likely cause damage. They are designed for 3.3v.
Either use a Teensy 3.x which can take 5v or look at a...
I knew I had read about his somewhere, some useful real world testing detail (especially if you want to implement continue) in this link
If you get stuck there are still commercial products out there, I use Synchole...
Hi, cool that you have a CR 5000.
I'm not speaking from in-depth experience of doing this with teensy but a couple of points:
- Din sync just counts pulses (rather than frequency) - your myClock routine is only...
@luni, I used your code at #3 - it works great. I added a marker like you suggested for 'report available' and also one for 'report read' so you can see new crash reports. Thanks Paul.
Thanks @Defragster, that helps.
As a quick hack I've used StreamUtils to write it to EEPROM on restart and then read it out at leisure.
I don't think there is an end of report marker and the CrashReports have...
I'm trying to track an intermittent fault on a teensy (micromod) project that runs off USB for most of the time.
The fault only happens very occasionally, when it does it locks-up then auto reboots after the 8...
