Interfacing ADS8556 with OMAP-L138

Other Parts Discussed in Thread: OMAP-L138, OMAPL138, ADS8556

Hello,

I am trying to interfacing ADS8556EVM with Zoom™ OMAP-L138 eXperimenter Kit. In order to do this, I used an SPI0 interface on OMAP-L138. This work exellent, but in our project I use Ethernet, and I could not use SP0 at the same time. Further I am trying to use SPI1 interface. This is work, but not properly, because I have an old version of OMAP-L138 eXperimenter Kit, and the output buffer, which connect to SPI flash, always driving SPI1_SOMI on the bus. Further I am trying McBSP1 interface to interfacing ADS with OMAP, but CLKSTP mode is not supported on OMAP-L138. And, as I understand, I can not use it in SPI master mode ?

In this situation, I see the only way - connecting ADS8556EVM with OMAP-L138 eXperimenter Kit via universal parallel port. Can anyone advise me how to do it?

I am using CCS v5.1, SYS/BIOS 6.33.04.39, BSL by LogicPD for SPI interface, and BIOSPSP for McBSP interface.

Thanks,

Ilya

Ilya,

Have you considered using the McASP on the device to connect the ADS8556 and OMAPL138. In the past we have helped customers connect the ADS8556 to connect to our DSP via the McASP. You will find some very useful information to achieve this on the following e2e post:

Hope this helps

Regards,

Rahul

Thanks for your reply,

I did not consider the McASP for this purpose. I'll try this way.

Thank you for your time,

Ilya
