cb_pcidas.c
- This intends to be a driver for the ComputerBoards PCI-DAS series.
+ This is a driver for the ComputerBoards/MeasurementComputing PCI-DAS
+ cards using the AMCC S5933 PCI controller:
+ - PCI-DAS1602/12, 16, 16jr
+ - PCI-DAS1200, 1200jr
+ - PCI-DAS1000, 1001, 1002
+
+
SO FAR IT WAS ONLY TESTED WITH PCI-DAS1200. PLEASE REPORT IF YOU ARE
- USING IT WITH A DIFFERENT CARD <ivanmr@altavista.com>.
+ USING IT WITH A DIFFERENT CARD <ivanmr@altavista.com>.
+
+ Options:
+ [0] - PCI bus number
+ [1] - PCI slot number
- Options:
- [0] - PCI bus number
- [1] - PCI slot number
+ Developed by Ivan Martinez and Frank Mori Hess, with valuable help from
+ David Schleef and the rest of the Comedi developers comunity.
