I'll have a look if something pops up.MartyMacGyver wrote:Hans,
Others have been having this problem as well and I shared your post with them. Thanks to your discovery, the problem may be resolved. An issue has been raised on Github regarding this: https://github.com/espressif/arduino-esp32/issues/286. You might want to subscribe to that issue on there to further track it.
I'm curious if you're seeing this issue with the ESP IDF or with Arduino-ESP32? A corresponding fix may be needed for the IDF.
Honestly, I have no idea why there's 2 different addresses for the same register, one that works and one that doesn't, and why expressif didn't just switch everything over to the working ones...
