I am using esp-idf v5.0.1 and lvgl as component release/v8.3 There is a very strange problem which i think it is indexing but maybe i am completely wrong so i will have to change the title the operands in a function and the usage o...

In the link https://forum.lvgl.io/t/implicit-declaration-of-function-gpio-pad-select-gpio/8177 shows to include rom/gpio.h to driver/gpio.h to solve the issues with esp-idf and esp_lvgl_drivers after this And https://www.esp32.com/viewtopic.php?t=18861 Shows that the .bit_num is changed to .duty_res...

I am trying to make an lvgl project with esp32. I have started with the https://docs.lvgl.io/master/get-started/platforms/espressif.html that guides you to include in component folder the lvgl and lvgl_esp32_drivers as git submodules. The drivers project is needed for the displays but on build there...

Unfortunately i was not thinking clearly i can set the delay not to portMax_Delay but to some milliseconds. but i still need to wrap it in if condition in order to know if this happend so the question is that does the semaphoreTake return something i tried to open to see the declaration but i did no...

Hi i have a high resolution timer set like this. esp_timer_handle_t timerHandle; const esp_timer_create_args_t timerArgs={ .callback = onTimer, .arg = NULL, .dispatch_method = ESP_TIMER_TASK, .name = "Measurement", .skip_unhandled_events = false }; esp_timer_create(&timerArgs,&timerHandle); I can us...

Is there a proper way to initialise a timer inside a class? I am trying to do a c++ project and i want to user the high resolution timer. The class is about XH711 adc 24 bit. I have an init function where i do everything needed for the adc and i want in there to init also the timer by seting the esp...

Hi i am trying to use MCPWM to move a nema 17 motor. I am using a TB6560 stepper motor driver and it setup is limmiting current to 1.5A and i am using 1/8 Microsteps. Motors is classic one 1.8degrees per step and 200steps per revolution. I am using the mcpwm_unit_0 and timer_0 and at mcpwm0A i am se...
