Description
What MCU/Processor/Board and compiler are you using?
ESP32S3 (Waveshare 7" touch screen monitor)
What LVGL version are you using?
v8.4
What do you want to achieve?
How can I update meter indicator position in main.ino code with signal from ADS?
What have you tried so far?
Any online help and LVGL widgets meter documentation.
How can I update indicator position in main.ino code?
I’m following this ( lv_meter_set_indicator_value(meter, indic, value) sets the value of the indicator.) in lvgl documentation, in my code eez created like ( lv_meter_set_indicator_value(obj, indicator, 0)
Code to reproduce
Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.
The code block(s) should be formatted like:

#include "images.h"
#include "fonts.h"
