Using the SPI bus

Hello,

Right now im playing around with the ST8M8 Discovery board, i have followed some tutorials and have build a few projects that fade the LED using the PWM signal. I would like to use the SPI bus in the future to read and process data from a mem sensor. Could someone please point me in the right direction to a tutorial to using the SPI bus, or maybe provide me with an example project? Any help would be appreciated #spi-example

You can use example in the FWLib

Thanks for the fast reply, I have looked at the example, but i can find UART, LIN and CAN examples but no SPI. Am I overlooking something? Thanks.

I have an example project where I use the 23K256 SRAM with the STM8S Discovery. It took 1 month to work, and the code is partly C, partly Assembly. I got no help from ST support, so I needed to find out myself...

Hello,

Please have a look at documents and files for family STM8 8-bits Microcontrollers where you can find STM8S firmware library

http://www.st.com/products/support/micro/files/stm8sfwlib.zip

  including SPI peripheral software examples for STM8S. Regards.

The FWLib had apparently been made UNavailable.

Only a smaller Std Peripheral Library is available. The spi.c is in the library. There is a simple example in this blog:

But it used only the output.
