SPI example

juliancox — Thu, 07 Nov 2019 11:42:16 GMT

Does anyone know where I can download an example project for the S08 MCU using SPI. In my case I am trying to communicate with a TI ADS1120. BTW. Why is the Processor Expert component shown as a SynchroMaster while its property (Channel) is shown as SPI? Can this component be anything other than a SPI?

Can you tell me the S08 that you are using?

You can check some code for the spi on the following link

https://www.nxp.com/docs/en/user-guide/HCS08QRUG.pdf

https://www.nxp.com/docs/en/user-guide/QE128QRUGSW.zip

Also for a news S08 like the S08P family, you can check the following link:

Please check the lab 6

I hope this will help you

Thanks for the information, but I cannot import any of the projects into CW 11.0. Which IDE was used to create them? FYI - I am using an S08 QE8, but I also have DEMOQE 128 board.

So far I have managed to confirm that I can send data (ProcessorExpert SendChar), but when I try to receive data (ProcessorExpert RecvChar) there is no serial clock and the operation returns a overflow error. Any ideas?

For the QE the sample code I believe was created on code warrior 6.x

For the P family was used code warrior 10.x so for these samples you should not have any problem to open it on CW 11
