Having trouble with the SPI-bus the new v15 Board.

Post by FredricN » Thu Jan 31, 2019 10:45 am

Hi

We are using the SPI-bus with external circuit’s and the built-in SD-Card.
Having trouble to get the basic SD card example’s to work with the new board,
It works fine with the v12 board.

The SCK line signal seems to be distorted if you analyze it with a oscilloscope.

Is there any hardware changes with the new board that causes this?

Using the latest pro ide v06.12 with API 38

Regards Fredric

Hi,

There were changes in the SPI bus. Could you try to connect your devices through a SPI isolator to avoid interference between the circuits?

Regards
