![]() There shouldn't be any more issues in your function calls and the infinite while loop, just pay attention which pointers are you passing into the HAL_RTC_SetDate and HAL_RTC_GetDate functions. I'm sure with this you can tweak your code to have it work. ![]() Because of our code it will take automatically time according to AM/PM. That's why the printf statement contains -> operators instead of just. Set the current time in 24hr format, don’t worry it won’t show you time in 24 hour format. or we can even leave the structure's name out and leave it anonymous - like you did in your code - we don't need it named at all since we already have a new type made out of it that we can use. } date_struct_type // Define and typedef a structure at the same time That code is identical to writing typedef struct date_struct In my code, I split up the structure definition and the typedef into two individual statements. That means, from that point on, you work with the structure as if it was just a variable type. In your code, you first define an anonymous local structure and immediately typedef it to create a new type. Web how to set the date/time in the ds3231 real time clock with the arduino. or pass a reference to the structure, but never a reference to the pointer It can be called and changed at any time. This operation does not need to stop and restart RTC. or pass the pointer into any hypothetical function A fim de ver o funcionamento, vamos montar o circuito com o RTC e um Display LCD via I2C. In this case, Hal is used RTC Setdate() and Hal RTC The settime() function can update the current date and time in real time during the RTC running phase. Printf("Month: %d\nDate: %d\nYear: %d\n", date_ptr->month, date_ptr->date, date_ptr->year) ![]() Use the pointer to adress the structure's values Typedef struct date_struct date_struct_type // make 'struct date_struct' into a new typeĭate_struct_type date // Declare a variable of the new typeĭate.month = 0x03 // Initialize the fields of the variableĭate_struct_type * date_ptr // Create a new pointer to the structĭate_ptr =
