Arduino for STM32

ok thanks
Can you check my syntax for the hardware timer class
I am not sure what is correct
see my last post

U2G8 OLED is working fine I have checked on other sketches

- Better re-check pinout for you board. On STM32F401CC TIM5 is connected to PA0/1/2/3. TIM2 is alternate function, not default.

You could compare to bluepill:

Hi there
I downloaded a Bluepill project and I can't work out why this won't work out on a Blackpill STM401
It is a quadrature LFO for analogue synthesisers
I have verified my connections to the OLED and the SPI DAC - both work fine
Is it something to do with the Timer commands? Sorry I am a bit of ...

You can't omit the MISO pin.
If you want use the PB3 and PB5 you have to set all pins to the same SPI3 peripheral instance as described in the PeripheralPins.c :



Amazing thanks. So if I understand correctly my instance was not working because I had not changed the MISO pin together with the ...

Do I need to download and install this SPI library? I am confused
https://github.com/stm32duino/Arduino_C ... raries/SPI
And if so how do I keep both SPI Teensy and STM32 on the Arduino IDE?

I would use the SPIClass command but I do not know how to omit MISO pin because I do not need it
so
SPIClass SPI(SPI_MOSI, SPI_MISO, SPI_SCK);
can I do
SPIClass SPI(SPI_MOSI,, SPI_SCK);
or
SPIClass SPI(SPI_MOSI, 0, SPI_SCK);
??
Cant find info on this

I am using this core
https://github.com/stm32duino/BoardMana ... index.json
And I have selected Black Pill F411CE

Sorry I am complete beginner here
I have used DACS MPC4822 and 4922 with success with Teensy 3.6 and 4.0
I decided to migrate a project from Teensy to STM32F411
The code I used successfully with Teensy does not seem to be working on the 411. I cannot get any clock or SDI to begin
I believe the lines ...

Yes, all pins are interrupt capable but you can use only 16 interrupts, so only one pin with same number can be used (eg. you cannot use interrupts on PA1 and PB1, only on one of them)

awesome much appreciated
