Hi, everyone

I have the trouble of Hytec 8401ADC’ working way. I can let it works well if I set the SCAN field to “1 second”. But if “I/O Intr" was set, there are no any responses. I use 10Hz/5V pulse to trigger Hy8401ADC. The driver was downloaded from SLS. So who can help me to let it works on interrupt way?

In my opinion, I think I made some wrong parameters in the function of Hy8401ipConfigure(…). I don’t know how to set the parameters of vector and interrupt state. In my example, I set ‘intl”=3, “inte”=1. Also I am not sure I need to change some switch on slots of VME or not.

 

They are abstracted from st.cmd :

#                                      slot int options

 IPAC6 = ipacEXTAddCarrier(&EXTHy8002, "8 6 10")

 

#-------- 8401 (Analogue Input)------------------------------------------------

#                 card,  slot, ipsl, intl, inte, aity, clks,  clkr, inhi, samp, spac, trig

Hy8401ipConfigure (  60, IPAC6,    A,  3,    1,    0,    0,    15,    0,    100,    1,   100)

 

It is the record what I used:

record(ai, "Hy8401:ADC-01")

{

  field(SCAN, "I/O Intr")

  field(LINR, "LINEAR")

  field(EGUF, "10")

  field(EGUL, "-10")

  field(DESC, "ADC Site A Ch 0")

  field(PREC, "6")

  field(EGU, "Volts")

  field(HOPR, "10")

  field(LOPR, "-10")

  field(DTYP, "Hy8401ip")

  field(INP, "#C60 S0 @")

}

 

They are the output information of VME/IOC:

#                                      slot int options

 IPAC6 = ipacEXTAddCarrier(&EXTHy8002, "8 6 10")
