How to detect, set and use BOD at runtime when using Arduino IDE for development?

[dattasaurabh82]

Board: ESP32-H2-mini-DevKit
Dev Env: Arduino IDE 2.3.4
ESP32 Arduino Core: 3.0.7

Code: [Select all] [Expand/Collapse]

1. #include "esp_private/brownout.h"
2. // #include "esp_adc/adc_cali.h"
3. // #include "esp_adc/adc_cali_scheme.h"
4.  
5. // const float BATTERY_THRESHOLD = 3.0;  // Battery voltage threshold for low battery detection
6.  
7. void setup() {
8.   Serial.begin(115200);
9.  
10.   // Enable brown-out detection
11.   esp_brownout_init();
12.  
13.   // Get the current brown-out detection threshold
14.   uint8_t threshold = esp_brownout_get_threshold();
15.  
16.  
17.   // Set brown-out threshold to 2.8V
18.   // esp_brownout_set_threshold(ESP_BROWNOUT_THRESHOLD_2_8);
19. }
20.  
21. void loop() {
22. }

Compilation error: 'esp_brownout_get_threshold' was not declared in this scope; did you mean 'esprv_intc_int_set_threshold'?

So I checked few files:

Code: Select all

./esp/v5.3.2/esp-idf/components/esp_system/port/include/private/esp_private/brownout.h
./esp/esp-idf/components/esp_system/port/include/private/esp_private/brownout.h
./Library/Arduino15/packages/esp32/tools/esp32-arduino-libs/idf-release_v5.1-632e0c2a/esp32h2/include/esp_system/port/include/private/esp_private/brownout.h

And in most of them I found:

So, basically no way to adjust/detect BOD from Arduino IDE?
Only by ESP-IDF during project setup?
