Arduino for STM32

So everyone who reads this has the answer, it is pin D24, position 17 in the left column of the 20 pin connector CN7, where it is covered if you use the arduino adapter shield for uno.

Where is the control for that?

And how would it compile if the symbol does not exist?

Okay, it is moved inside the setup routine. I tried that originally. It doesn't work.

In this excerpt, with managed ssel not enabled, setup() completes and the message in loop() "waiting for command" is received and displayed in the serial monitor. But if setSSEL() is called, no messages appear in ...

Hi,

I am using a NUCLEO-144 F722ZE. I am trying to enable CS pin management by the SPI engine.

Here is a sample code


#define SPI_SPEED 50000000
SPISettings spi_settings( SPI_SPEED, MSBFIRST, SPI_MODE0);

const int CNVSTPin = 10;
const int SDIPin = 11;
const int SDOPin = 12;
const int CLKPin ...

Hmmm... there are four options; mass storage, STM32CubeProgrammer SWD, STM32CubeProgrammer Serial, and STM32CubeProgrammer DFU,

The first two, mass storage and SWD, succeed in loading the bin. The latter two, Serial and DFU do not. Thank you, now, I think, I can turn to programming the device ...

Always remember to check MCU datasheet.

Yes, I am a big fan of datasheets. Getting the environment working is something I try to do early, after a quick perusal, then learn about the API and the part, then think about design and then launch into the details and then one more pass over design and ...

I see no error in the upload log. Anyway if it does not work update the STLink firmware using the STM32CubeProgrammer.

Where are the instructions for using the STM32CubeProgrammer? Can it be integrated into the Arduino IDE?

Thank you

One further question, to save a bit of time:

I need to use interrupts, clocks, and SPI.

Usually I use the attachInterrupt() and detachInterrupt(), the intervalTimer or TimerOne library, and whatever SPI library is provided for the board.

Are those the right API's for those capabilities in this ...

Found it. It is another menu item further down

It gets stuck uploading, as shown here. The file navigator opens too. When closed, it reopens.


Sketch uses 17416 bytes (3%) of program storage space. Maximum is 524288 bytes.
Global variables use 1316 bytes (0%) of dynamic memory, leaving 260828 ...

Where do I select the part number?

Have not seen any option for that.
