  4. [SOLVED] SPI slave with DMA

    Vicolaships

    …ted out, it is for F2, F4 and F7, as you probably noticed. Here, we are talking about blue pill (F1), right? F1 and F3 do not have that feature. Without knowing your code it is hard to evaluate what can be wrong. Btw, I posted here some working master/slave ex…

    petronel

    trying to use MFRC522 with my STM32F103 (blue pill). It compiles fine but the code seems to crash at SPI.beginTransaction(SPISettings(SPI_CLOCK_DIV4, MSBFIRST, SPI_MODE0)); // Set the settings to work with SPI bus
  11. from stm32 to stm8s

    ag123

    … decent ‘delegate’ processors, in particular if i run out of pins say on maple mini / blue pill i may resort to ‘delegate’ some io functions to a separate mcu, e.g. a keypad controller, but for keypad i’d guess one way is to chain them up using resistors and u…
  12. issue with sd card

    stevestrong

    … check the 3.3 V on the card module. It is well known that the 3.3 V regulator on the blue pill is not very strong, in which case I recommend to use a separate 3.3V supply (eventually from the MM) for the SD card module alone.

    Rick Kimball

    …u look at the wiki and posts here you will see this is a common problem people with a blue pill have to deal with. The bottom line, if you have a computer that expects a USB standard 1k5 pull up resistor then it will never enumerate properly which will prevent…

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

    stevestrong

    Yes, it runs on blue pill. It can be adapted for F4 as well, the DMA part needs some change for that.
