in `components/esp_system/task_wdt/task_wdt.c` you'll find if (esp_task_wdt_isr_user_handler != NULL) { esp_task_wdt_isr_user_handler(); } which has a declaration in components/esp_system/include/esp_task_wdt.h: /** * @brief User ISR callback placeholder * * This function is called by task_wdt_isr f...

I tracked this down to `temp_sensor_read_celsius()`, removing it fixed the latency problem.

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...
