What's handle on HAL (hardware abstraction layer) STM Cube MX ? Handle is often used several times.

Question

I think its like a pointer, a reference to memory. Is that right ?

Answer 1

https://visualgdb.com/tutorials/arm/stm32/adc/

Configuration ADC (analog digital converter):

HAL_ADC_Init(&g_AdcHandle);

Answer 2

Can you give some code? It is a word that can be used as a data structure for handle resourcer and used for callbacks of interruptions.

Answer 3

In that case you can notice that definition :

ADC_HandleTypeDef g_AdcHandle;

That is a data structure for handle the ADC, here you give all configuration parameters of your ADC, this configuration is initialized with HAL_ADC_Init,
