STM32_test example does not compile on latest version and STM core #320

Open toogooda opened 3 years ago

Firstly I would like to say the capability and documentation for this library is amazing so thank you :)

The latest update of SdFat seems to have made the STM32_test.ino example out of date.

static SPIClass mySPI2(2); no longer works as there is no matching constructor for

SPIClass::SPIClass(int)

You now need to specify the SPI pins something like this:

static SPIClass SPI_2 (PB15, PB14, PB13); For SPI2

Which STM32 board support package are you using? There are several.

I have not decided how to support STM32 so have not modified examples.

At this point there are almost 200 Arduino style boards so I can only provide specialized examples for a limited number of boards.

Thanks for your response, The official core by ST stm32duino/Arduino_Core_STM32 latest version 2.0.0 I am using F103RET but I am pretty sure they all use the same SPI constructor... ST also make it easy by making the SPI/I2c/USART on the same pins across most of there range so a simple example with SPI 1 and SPI2 should work on their entire range.

Yes, the ST package uses these constructors for all boards:

    SPIClass();
    SPIClass(uint8_t mosi, uint8_t miso, uint8_t sclk, uint8_t ssel = (uint8_t)NC);

I wrote the example when the only STM32 support was here with this constructor: SPIClass(uint32 spiPortNumber);

I will provide an option to use either package.

You are lucky to use the F103RET. I use high end STM32 boards with ChibiOS but many high end boards fail with the ST Arduino package.

Here is an issue for NUCLEO-H743ZI2 I posted on Feb 8, 2021. ST planed a fix for 2.0.0 but now plans for 2.1.0 or later.

Both options sounds perfect :) Thanks again for this great library!
