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 driven Interrupt enabled handlers for a Wroom32 (UART), NRF24L01 (SPI), and I2C (OLED displays). I have working, interr…

It is related since it addresses a similar topic. Since there are two questions wrapped up here, I’ll go with the FreeRTOS_IO first. Somewhere in the FreeRTOS_IO documentation there was mention of using queues gracefully with such things as SPI, USART, and I2C drivers. Naturally, once you start t…

[image] madyn: I’ve looked at the data link in the other post that I had never seen. FreeRTOS_IO might help with #1, blocking, but apparently this version supports absolutely none of the other features I need. The aim of common IO is to provide a common interface which you implement for your …

As far as I can tell, when you removed the zero footprint mode, you took out at least one feature that I wanted. At the level (I/O drivers for a particular chip type), that I need, I am not seeing how the existing code would be useful. It would be if I wanted this code to run on multiple platforms…

Given SPI, Serial, and I2C, I started working on I2C in the framework of the STM ecosystem. With any interface, receive and transmit are options. For I2C, I have blocking mode, DMA, and IRQ mode working. None of these need queues. Oddly enough, the implementation of I2C with queues seems to avo…

[image] madyn: It would be if I wanted this code to run on multiple platforms, but that is not the case. Then you are right - it probably is not suitable for your application. [image] madyn: Writing a queue at the application level, reading it into a buffer, then sending that buffer seem…

In the STMicro world as provided by CubeMXIDE, there are a number of (rather awkwardly) written drivers for each subsystem. They have a crude form of semaphore built into them (which may not work). There’s generally a driver for blocking I/O, Interrupt driven I/O, and DMA I/O. My drivers (as orig…

I’ll look, in summary, at three interfaces, SPI, I2C, USART. Each has three native modes. Blocking, Interrupt, DMA. There’s a fourth mode, Queues. That opens up a can of worms. For the three interfaces: I2C: working in blocking, Interrupt, DMA. Transfer rate limited by bus speed. Queue, ha…

[image] madyn: A universal driver cannot make sense with only one model considered, there needs to be a different model for each interface. Thanks for summarizing! I agree with your assessment and the assessment of @aggarg . A universal drive interface will only make sense if your underlying d…

The advantage I have here is that, with a bit of connivance, the initialization for each driver family is the same, or nearly so. for I2C: uint32_t create ( char which = 0, int IN_QUEUE_SIZE = 0, int OUT_QUEUE_SIZE = 0, I2C_TRANSFER_MODE IN_MODE = I2C_BLOCKING, I2C_TRANSFER_M…
