ESP32 Forum

I am trying to use Neopixels on the ESP32. I need to lock out all interrupts during the high period too insure accurate timing.
It look like the Ardunio function nointerrupts does not work.
I have tried to use different methods to do this but have ran into issues or they did nothing

noInterrupts();
XTOS_DISABLE_ALL_INTERUPTS;
intEnable_saved = XTHAL_GET_INTENABLE();
intEnable_saved = getIntEnable();
XTHAL_SET_INTENABLE(zero);
setIntEnable(zero);

How can I disable and enable all interrupts during a critical section in Ardunio IDE if noInterrupts() and interrupts() don't work?

Hi, I'm with the same problem. Could you solve it?

Moved to the Arduino subforum. General advice: if you are thinking of doing something that needs disabling of interrupts, see if there is not a peripheral that can do the job better than the manual bitbanging you're thinking of.
