30 Oct 2009 10:00 SPI Slave Select Functionality

Hi everyone.
In my current project I use Diolan usb i2c spi adapter - U2C-12 as a master device and several spi slaves. My task for now to call one of the several slave devices at the time which are connected to the master device. I guess in this case the Slave Selection is the right choice. Does anybody know how is it possible to use spi slave selection by using diolan u2c-12 device?
Thanks for the help.

Hi.
Yes, you can use SPI Slave Selection with Diolan U2C-12 adapter. Test this ability by using Diolan Control Panel Application. You can configure this ability in the main menu item “Options”->”Spi configuration” dialog. Check “Slave Select” item and choose slave select pin you need. The Active High function is also available. You can also use slave select functions for your programming needs. There are U2C_SpiConfigSS(); U2C_SpiReadWriteSS(); U2C_SpiWriteSS(); U2C_SpiReadSS(). For more details you can read documentation on the Diolan site. Here is the link to u2c 12 docs. The article about SPI Interface is also available as far as I know.
