Hey,

Is there any example how to program SPI code TM4C1294 without using TI-RTOS ?

It will be helpful on sharing that !!!!!

Thanks and regards,

Hi,

There are some SPI examples you can refer to under <TivaWare_Installation>/peripherals/ssi. These are non TI-RTOS examples.

Hey Charles ,

Thanks for the reply. I tried using the spi_master code to connect with a slave. But I able to see the data from MOSI line through oscilloscope. But i am not able to do readback MISO line is always low.

And I can see the clock and CS for the MOSI data

The same way master has to generate clock for the data transfer in MISO? there is no trace of clock after the master data is sent

I am sending data {0x97,0xFF,0xF1}. The purple line is clock and yellow is MOSI data.

Is there any configuration I am missing?

It would be so helpful if you help solving this.

Thanks and regards,

Srinivasan

Hi,

I'm not clear with your question. So what is on the MISO? You didn't show MISO signal?
