    If you try to use it with the SPI port, use the sdfatEx class, that’s likely the only one that can keep up with the speed in SPI mode. For SDIO, use the files from this PR: https://github.com/victorpv/Arduino_STM … SdioF1.cpp Those are the very latest I am usi…

    Yes, I put STM32 core in hardware folder but I am using 1.6.9 so I don’t check if examples changes. Sometimes it happens that instead of using the portable sketchbook folder it uses the folder in your home folder. Just manually open a sketch in the portable fo…

  20. simple sound player: PWM audio output, with DMA, without timer interrupt

    victor_pv

    It’s a different feature than the burst. In the burst, you can update several timer registers at once, because the timer will generate several DMA requests instead of one. The repeat feature is more like the opposite (although both can be used together), the t…
