SPI slave transfer using KSDK 2.0

javierhernande1 — Fri, 01 Jul 2016 21:43:10 GMT

Hi!,

I'm trying to send the value of eCompass via SPI from the FRDM-K64F. Based on the KSDK 2.0 examples I have made this KSDK 2.0 project.

SIMPLY_ROVER/main.c at master · spock540/SIMPLY_ROVER · GitHub

I have been reading each line and typing in the new project to try to understand the code and go learning C. My knowledge of C and Sensor Fusion are very poor.

I wanted to test the code but I encounter my first problem, when the code is executed not print anything on the console (in minicom). It's as if all calls to print() are omitted. I have tried in another KDSK 2.0 project and works well.

What is the reason for this? I also appreciate your suggestion about the code for transfering data in slave mode.

I tried using this API, Kinetis SDK 2.0 API Reference Manual: SPI Driver

but I found the fsl_spi.h file in the directory. Only fsl_dspi.h

Greetings

I was reading this and I tried with -specs=rdimon.specs but not works to me.

Hi Javier,

I think that the following post created by our colleague Erich Styger might be helpful for you, it explains how to enable semihosting with KSDK 2.x:

Regarding the SPI slave example, you can use one of the DSPI example projects that comes with KSDK:

Hope it helps!
