I'm interested - do you have your component on github?

Actually, there is a recommended parasitic configuration that uses two output pins from your CPU, one to drive a MOSFET to provide a better power supply for the single data/power wire. See Figure 6 in https://datasheets.maximintegrated.com/ ... S18B20.pdf

https://www.google.com/search?q=zoneinfo Exactly that was not useful to find the solution. It was not a matter of defining the time zones, but which syntax to use . I had the same problem - usually with most environments I'd use TZ="Pacific/Auckland" or sometimes ":Pacific/Auckland", which is what ...

Thanks Neil, that first link answers my question I think - seems like the key is to select a second book, and then the whole reader account thing swings into action. I'll have to give that a try... Thank you for asking them, and again, for your excellent book. EDIT: I bought a second book and when I...

Quick question, Neil - do you know whether creating an account on leanpub as a reader is supported? Somehow the system knows to email me when updates to your book are available, but it's not clear to me where my "profile" exists on the site, because I haven't created an account, nor do I seem to nee...

Ah, so if the channel is uninitialised then the interrupt is disabled? That makes sense I think. Currently my PR will clear the interrupt but doesn't disable it.

BTW, for completeness: https://github.com/espressif/esp-idf/issues/1815

In terms of finding a root cause, I've increased my RMT operation rate by 100x and added a "crash on demand" button, and I'm able to easily replicate the RMT crash-on-init error, so I'm using this to explore the cause of this problem. I've been able to tell with certainty that the crash is happening...

@apuder: I'm not sure how much you already know, but some background such as this this might help too: https://www.electronics-tutorials.ws/lo ... istor.html

My apologies if this is all old news to you.

No, I haven't tried those - I see that rmt_config() calls periph_module_enable(), but does not call disable itself, so I'll try a call to periph_module_disable() prior and see if that helps. Thanks for the suggestion.

I'd like to say thanks too - it's a useful book that provides a good introduction to each aspect of the ESP32, and helps me work out what areas I need to dive into in more depth.
