Are interrupts queued after call to noInterrupts()?

[alexsr]

Hello everyone,
I am using an ESP32 DevKit C to communicate with an IMU.
This external device sends data when a data-ready pin is active. Therefore I trigger an interrupt on this pin.
However, I need to read the data that is sent by the IMU and send it to a different device. This would be susceptible to race conditions though.
I was wondering if using noInterrupts() followed by a data copy and interrupts() works here.
Especially, whether or not an interrupt, that is triggered while noInterrupts() is active, is queued and triggered once interrupts are enabled again.

Thank you.
Alex

noInterrupts() etc are all non-implemented stubs: https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/Arduino.h#L76-L79

Interrupts will still fire even after calling those functions.

Oh, that's unfortunate. Thank you though.
