The design of this series is very nice, * since each board has an on-board DSP (Texas Instruments TMS320C52). * However, a few details are a little annoying. The boards lack * bus-mastering DMA, which eliminates them from serious work. * They also are not capable of autocalibration, which is a common * feature in modern hardware. The default firmware is pretty bad, * making it nearly impossible to write an RT compatible driver. * It would make an interesting project to write a decent firmware * for these boards. * * Data Translation originally wanted an NDA for the documentation * for the 3k series. However, if you ask nicely, they might send * you the docs without one, also. */ #include <linux/module.h> #include <linux/delay.h> #include <linux/interrupt.h> #include <linux/comedi/comedi_pci.h> /* * PCI BAR0 - dual-ported RAM location definitions (dev->mmio) */ #define DPR_DAC_BUFFER … #define DPR_ADC_BUFFER … #define DPR_COMMAND … #define DPR_SUBSYS … #define DPR_SUBSYS_AI … #define DPR_SUBSYS_AO … #define DPR_SUBSYS_DIN … #define DPR_SUBSYS_DOUT … #define DPR_SUBSYS_MEM … #define DPR_SUBSYS_CT … #define DPR_ENCODE … #define DPR_PARAMS(x) … #define DPR_TICK_REG_LO … #define DPR_TICK_REG_HI … #define DPR_DA_BUF_FRONT … #define DPR_DA_BUF_REAR … #define DPR_AD_BUF_FRONT … #define DPR_AD_BUF_REAR … #define DPR_INT_MASK … #define DPR_INTR_FLAG … #define DPR_INTR_CMDONE … #define DPR_INTR_CTDONE … #define DPR_INTR_DAHWERR … #define DPR_INTR_DASWERR … #define DPR_INTR_DAEMPTY … #define DPR_INTR_ADHWERR … #define DPR_INTR_ADSWERR … #define DPR_INTR_ADFULL … #define DPR_RESPONSE_MBX … #define DPR_CMD_MBX … #define DPR_CMD_COMPLETION(x) … #define DPR_CMD_NOTPROCESSED … #define DPR_CMD_NOERROR … #define DPR_CMD_ERROR … #define DPR_CMD_NOTSUPPORTED … #define DPR_CMD_COMPLETION_MASK … #define DPR_CMD(x) … #define DPR_CMD_GETBRDINFO … #define DPR_CMD_CONFIG … #define DPR_CMD_GETCONFIG … #define DPR_CMD_START … #define DPR_CMD_STOP … #define DPR_CMD_READSINGLE … #define DPR_CMD_WRITESINGLE … #define DPR_CMD_CALCCLOCK … #define DPR_CMD_READEVENTS … #define DPR_CMD_WRITECTCTRL … #define DPR_CMD_READCTCTRL … #define DPR_CMD_WRITECT … #define DPR_CMD_READCT … #define DPR_CMD_WRITEDATA … #define DPR_CMD_READDATA … #define DPR_CMD_WRITEIO … #define DPR_CMD_READIO … #define DPR_CMD_WRITECODE … #define DPR_CMD_READCODE … #define DPR_CMD_EXECUTE … #define DPR_CMD_HALT … #define DPR_CMD_MASK … #define DPR_PARAM5_AD_TRIG(x) … #define DPR_PARAM5_AD_TRIG_INT … #define DPR_PARAM5_AD_TRIG_EXT … #define DPR_PARAM5_AD_TRIG_INT_RETRIG … #define DPR_PARAM5_AD_TRIG_EXT_RETRIG … #define DPR_PARAM5_AD_TRIG_INT_RETRIG2 … #define DPR_PARAM6_AD_DIFF … #define DPR_AI_FIFO_DEPTH … #define DPR_AO_FIFO_DEPTH … #define DPR_EXTERNAL_CLOCK … #define DPR_RISING_EDGE … #define DPR_TMODE_MASK … #define DPR_CMD_TIMEOUT … static const struct comedi_lrange range_dt3000_ai = …; static const struct comedi_lrange range_dt3000_ai_pgl = …; enum dt3k_boardid { … }; struct dt3k_boardtype { … }; static const struct dt3k_boardtype dt3k_boardtypes[] = …; struct dt3k_private { … }; static void dt3k_send_cmd(struct comedi_device *dev, unsigned int cmd) { … } static unsigned int dt3k_readsingle(struct comedi_device *dev, unsigned int subsys, unsigned int chan, unsigned int gain) { … } static void dt3k_writesingle(struct comedi_device *dev, unsigned int subsys, unsigned int chan, unsigned int data) { … } static void dt3k_ai_empty_fifo(struct comedi_device *dev, struct comedi_subdevice *s) { … } static int dt3k_ai_cancel(struct comedi_device *dev, struct comedi_subdevice *s) { … } static int debug_n_ints; /* FIXME!
