Hi team

For those who use RTOS, how do you use flags? or what's the alternative of flags in RTOS? I know there is semaphore, but I don't think I should keep posting semaphore right?

For example, that's what I mean if I was using bare metal code.

volatile uint8_t global_flag = 0;

void scanInput(void);
void doStuff(void);

while(1){
  scanInput();
  doStuff();
}

void scanInput(void){
  // some magical debounce code here
  if (userInput == 1) global_flag = 1;
  else global_flag = 0;
}

void doStuff(void){
  if (global_flag == 1){
    // do stuff
  }
}
