What I’m looking for are similar support routines for I/O as were in the FreeRTOS-IO package. After some research, I find that the code is no longer available although some examples have been updated in 2024. All links lead to dead ends or things that want to have FreeRTOS_IO.h included. I seem t…

I missed the part where it integrates queues into (at least) I2C support and SPI support. That was a desired feature. I also replied in more depth on my other post in the libraries section. Perhaps that clarifies a bit. Thanks

The other discussion is here: [image] FreeRTOS_IO and Updating STM32CubeMXIDE Libraries I’m going to put this here and hope that it is close enough in group. I’m working on a successful (it’s working) project using STM32CubeMXIDE. What I want to implement are queue driv…

There are several issues. Bear in mind that for I2C you need master/slave determination and receive/transmit capability. For SPI you need much the same, but implemented differently because of the hardware. For USART you need only receive/transmit capability unless you are going to use multiproces…

[image] madyn: Remember that these drivers need, at a minimum, three basic routines: create (these are C++ drivers) with new. Configure queues, modes, I/O pins if needed, etc. Send, generalized send from a buffer (ignores queues for now) Receive, generalized receive, and send to a buffer. S…

I already have interfaces for SPI, I2C, and USART. For the moment, I’m not dealing with others (CAN, I2S, etc). I wanted a method to use queues with these peripherals. Reading from a serial device that drives a queue is desirable. That’ll come with the USART implementation (when debugged) and be …

queues work, the basic mechanism is to make a task which (say for receive) receives a byte of data in blocking mode with infinite timeout, then transmits to the queue with portMAX_DELAY. This seems to chew up a lot of time, is there a better method? blocking mode works (but you have to be careful …

[quote=“aggarg, post:9, topic:21405”] A task received a byte and then it is sending this received byte to other task? You can consider buffering and sending only after x number of bytes are accumulated. It depends on your use case. [/quote] There are three use cases, one for each interface: I…

[image] madyn: while (1) { HAL_UART_Receive(me->huart, &buf, 1, HAL_MAX_DELAY); xQueueSend(me->receive_queue, &buf, portMAX_DELAY); } If your queue has space, xQueueSend will return immediately and call HAL_UART_Receive. It seems like HAL_UART_Receive is a blocking call - how does imp…
