OK Richards, thanks for the intro. Avoid asking multiple distinct questions at once.

Microchip® Advanced Software Framework

Initiate a multi-byte write operation on an UART peripheral. Initiate a completely multi-byte read operation on a UART peripheral.

The RTOS task that calls the transmit function exits the transmit function as soon as the transmission starts. There is an interrupt for every byte. Posted by Borge Strand on January 29, Reception happens in the background, while the microcontroller is executing application code.

[RTOS Support] generic UART example for STM32 using CubeMX HAL

This driver is provided with an application note, and an example project uatr demonstrates the use of this function. Pryda 4 Design everything as a time-triggered system.

Is the RTOS really necessary? Which way is better in my case? Should I simply do the UART transfers in tasks with low priority, assuming the OS will freeertos things out, or should I rather have tasks blocked while waiting for data, with semaphores, interrupts etc.? Depends on the protocol uadt really. Thread aware file system Hint: There is a single interrupt for the whole transfer.

Posted by Borge Strand on January 28, But it would ruin the USB transfers. You're asking for implementation opinions. Delivered online or freerots.

UART send and receive integration with freeRTOS

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. You don't dreertos RTOS just to make something "faster", but to make management of many parallel and interdependent tasks easier. See the How to Ask page for help clarifying this question. First, the way the OS sorts things out is by having tasks block on queue etc waiting for data.

Which way is easier to handle and guarantees uwrt best performance? This will be less than the requested number of bytes if a time out occurred. I think there are 2 ways to do so. The archive is updated every week, so will not always contain the very latest posts.

[RTOS Support] UART & SPI through FreeRTOS

Defines the driver behavior. Or are there better approaches still? Other RTOS tasks execute while the transmission is in progress. The tasks in question will have fairly low priorities, as the data rate is non-critical and low. Structure that defines the UART bus and transfer parameters, such the baud rate and the number of data bits.
