I2C latency with enabled WiFi

Hi, I am trying to build a voltage regulator control loop, that reads voltages from an external ADC (ADS1015) connected via I2C. The ESP32-S3 is connected to WiFi. The loop works as follows: The ADC notifies the ESP32-S3 through an ALERT pin interrupt, the ISR sets a ready flag. The program then rea...
