Section 3 - IEEE-488 STD (GPIB) Programming * * Set the instrument to GPIB address 1: * Press [1] [SECOND FUNCTION] [MEGA] * * * Set the instrument for no carriage return or line feed (EOI only): * Press [0] [SECOND FUNCTION] [ALL CHAN] * * This program assumes the name of the device at address 1 hasn’t been * changed in IBCONFIG (it’s still called DEV1, which is the default.) * * The status variables IBSTA, IBERR, and IBCNT are defined in DECL.H. * Each bit of IBSTA and each value of IBERR are defined in DECL.H as * a mnemonic constant for easy recognition in application programs. In * this example, these mnemonic definitions are logically ANDed with the * variable IBSTA to determine if a particular bit has been set. The mnemonic * definitions are equated with the variable IBERR to determine the error * code. * * The function GPIBERR is called when a NI-488 function fails. The * error message is printed along with the status variables IBSTA, IBERR, * and IBCNT. * * The NI-488 function IBONL is called from the main body of the program or * from the function GPIBERR. When the second parameter of the function * IBONL is zero, the software and hardware are disabled. * Execution of this program is terminated after the call to the function * IBONL to disable the software and hardware. * * The function EXIT is used to terminate this program within the function * GPIBERR. The exit status is set to 1 to indicate an error has occurred. * */=================================================================== */ #include #include 3-14
