I am using the nucleoH743ZI with Free RTOS. Try to send data via UART from each TASK.In Round robin scheduling, First task sends the data via UART, then context switch Second task tried to send the data via UART, handle of the UART was in Busy always.
In "prioritized preemptive scheduling", able to send the data to UART from each task.For the round robin, I set the time slice of 200 ms.Have the doubt like how much time taken to change the state of UART handle from "Busy" to "Ready"?.
