interfacing EVAL-AD7175-2 with MAX32666FTHR

I have this specific error with regards to spi.init.type.

It seems the syntax 'type' is not declared, and what would be the parameter to use if I'm using an maxim microcontroller?

Hi kimedia,

At the moment, only the MAX32650, 655, 660 and 78000 are officially supported by no-OS. However, adding platform drivers for the MAX32666 is a work in progress (you can checkout this branch https://github.com/analogdevicesinc/no-OS/tree/staging/max32666, because the SPI should be working). This assumes that you haven't implemented the no-OS drivers for the MAX32666 yourself.

The init parameters for the SPI interface indeed seem to be wrong. For the Maxim platform, these should be used:

struct max_spi_param spi_extra = {
		.numSlaves = 1,
		.polarity = SPI_SS_POL_LOW
	};

	ad7176_2_init.spi_init.chip_select = 0;
	ad7176_2_init.spi_init.device_id = 1;
	ad7176_2_init.spi_init.max_speed_hz = 1000000;
	ad7176_2_init.spi_init.mode = SPI_MODE_3;
	ad7176_2_init.spi_init.platform_ops = &max_spi_ops;
	ad7176_2_init.spi_init.extra = &spi_extra;

Also, here's a guide on how to build a project using the no-OS build system: https://wiki.analog.com/resources/no-os/build. In your case, the TARGET should be max32665.

As you've mentioned using the MAX32666FTHR, the QSPI1 should be used (pins A0-A4) (more details here: https://datasheets.maximintegrated.com/en/ds/MAX32666FTHR.pdf).

Thanks,

Hi CiprianR 

Thanks for the information. It seems the github link you refer is inaccessible.

Greetings kimedia 

It looks like the link is valid, but there was a comma right after, which was interpreted as part of the link. Alternatively, you can checkout the staging/max32666 branch in the no-OS repository. Also, I've corrected one mistake in the code from my previous answer (id -> device_id), sorry about that.

Regards,

Ciprian
