What was the problem ? Normally using the json file is simpler, but does the very same thing.

Re: IRlib on STM32?

I was looking at that last year, and have intention to continue when i have time to dig the files and then continue with it. I was using the ST application note linked by Andy in the previous post. That AN is for F0 and F3 chips that include an internal circuit to connect 2 timer outputs, in a way ...

Re: STM32L4 Core

Sorry but I can't find the json file to install the package. Could you, please, give the correct path to be added on Arduino Preferences? Thanks a lot and ciao from Italy Sorry for the delay. Got to clean up a few things for Ladybug/Butterfly and then there will be a new *.json file. Sorry for the ...

Re: STM32L4 Core

Quick update. Added SDCARD support via SDIO and SPI for Ladybug/Butterfly/Dragonfly. Also for NUCLEO-L476RG SDIO is exposed on the PC8/PC9/PC10/PC11/PC12/PD2 pins, and SDCARD via SPI on PC10/PC11/PC12/PD2. The code will work with most breakout boards that have no pullups on CS/DAT3. SDIO is a tad fi...

Re: I2S example code

Thanks, I have been having a look at both the Arduino and your implementation. Are you using the STM drivers for the lowest level? or you wrote your own? I'll see if this coming week I have some time to read how the i2s peripheral works in the F1 and start writing. I'll have to ask you some things ...

Re: I2S example code

Madias, did you ever turn the i2s code into a library? I am getting back to work on the stm32 and just ordered some pt8211. I want to clean up the wav player code and turn it to use one of those. ArduinoZero (MKRZERO) added a I2S class now that is also supported by a ArduinoSound libary: https://gi...

Re: RTOS integration

Reply #2. Some thoughts about queues. You cannot do those things not because C is lacking ... Any kind of user side (aehm, task side, as opposed to kernel side) fifo style queue can be implemented via atomics and semaphores. Hence as long as you have those 2 types of core object available you can im...

Re: RTOS integration

That you for sharing, but you answer exactly what I had specifically asked to not reply with, which is "there is RTOS XYZ and you should use that". Please note, that the first thing I wrote is that an existing working API can be used as a guidance in all the decisions you have to make. Af...

Re: RTOS integration

What about adapting FreeRTOS or CoOS for that core? Someone did a long time ago for libmaple with older versions. When I decided to adapt the latest versions of both, I compared and found very few changes where needed, like 4 or 5 lines total. Victor, the question was not "which RTOS" or ...
