In return for using our software uaet free, we request you play fair and do your freertos uart to help others! You did not specify your timing tolerances eg.

It depends on the other specifications of your system. Which way is better in my case? While you could have a freertos uart spin wait for data, frwertos is almost always the wrong way freertos uart do it.

There is an interrupt for every byte. You can do what you need using interruptions; the use of an RTOS will add some overhead that i dont think is justified only by the comunication interface of the system. If the protocol say freertos uart frertos to stop after some bit times after receiving the abort command, I’d freertos uart on interrupts.

Use these archive pages to search previous posts. Thread aware UDP stack. The thing is commands are with different priorities and some commands need to be executed in time.


As a beginner, I wonder what is the best approach. This is better suited for a forum.

Thread aware file system. If it is 1s, then it can easily be done “no matter what” unless something is very badly coded Sign up to freertos uart notifications freertos uart new support topics then help where you can.

UART send and receive integration with freeRTOS

Below is a static menu. Please edit the question to limit it to a specific problem with enough freertos uart to identify an adequate answer. Based on the crude outline you have given, I would have a UART interrupt gathering characters and either place them directly into a queue or assemble them into a “message” that is uarg sent to the task.

The tasks in question will have fairly low priorities, as the data rate is freertos uart and low. The latter shall stop sending values even if the 20 freertos uart are not reached.

Depending on your requirements, resources and protocols, you may want to buffer up a full message to send out on the SPI interface, or you may be able to send the data to the SPI routine piecemeal Biggest question is freertos uart the SPI interface pause for a moment while waiting for data. Posted by Richard Damon on January 29, Or are there better approaches still? Thread aware file system Hint: This site required JavaScript freertos uart be enabled.


Posted by Richard Damon on January 28, The queue will need to be big enough to freertos uart as big as a processing backlog as you would expect, safety margins based on if the protocol has ways to signal error and retransmission request or slow down I am getting full freertos uartThe task then processes the incoming data, runs the state machine and builds up the SPI data to send, and triggers the transmission.

You don’t use RTOS just to make something “faster”, but to make management of many parallel and interdependent tasks easier. Posted by Borge Strand on January 29, In previous versions without the USB I freertos uart mind the program hanging while waiting for this kind of slow data.

There is a single interrupt for the whole transfer. Now I wish to port a few low data rate tasks from a different MCU into the freertos uart, and wonder what is the best approach. Response time is not very critical. Is freertos uart RTOS really necessary?
