Tool/software: TI-RTOS
Hi,
in my current implementation, I am facing the following problem: I have two tasks that handle two different UARTs. The structure of both task is nearly the same:
void readInput(void)
{
while(1)
{
UART_read(Uart, buffer, 1); // calls callback function after successful read
Semaphore_pend(sem, BIOS_WAIT_FOREVER); // return semaphore from callback function
// Do something
}
}
For the next step, I place a breakpoint at the beginning of my callback function. If I now stop through several breakpoint calls I can see the following: the callback function is either triggered by the HWI or a task (?):
What is the difference between the two calls? My question is pointing at this: within an HWI I cannot use or call any semaphore functionalities, whereas this is possible within a task context.
