ESP32C3 critical interrupts
Posted: Sun Nov 14, 2021 8:06 pm
Hi. I use timer interrupts to make dynamic indication on 7-segment indicators (interrupt period 1000us for show time and 50us for delay between periods to give time for LEDC to change state). To make variable brightness I use LEDC on common pins of the indicator (40kHz 4bit). It works well until wifi connection is established. After connection i see slight glitches on the indicator, i guess some interrupts are not handled in time. Are there any possible ways solve this problem?
