8. As is always the case with interrupt handlers it is easy to introduce bugs into your program and generally hard to track down these bugs Be careful when writing this function Data Gating Sometimes you may wish to monitor data from some input channels and not others The function e1432 set enable enables or disables data from an input channel or group of channels If data is enabled then the data can be read using e1432 block available and e1432 read xxx data If data is disabled data from the specified channel is not made available to the host computer This parameter can be changed while a measurement is running to allow the host computer to look at only some of the data being collected by the HP E1432A module While data from a channel is disabled the input module continues to collect data but it is not made available to the host computer The host can then switch from looking at some channels to looking at others during the measurement In contrast the function 1432 set active completely enables or disables a channel and can t be changed while a measurement is running For order tracking measurements this function can be used to switch between receiving order tracking data ordinary time data or both 4 28 HP E1432A User s Guide The C Language Host Interface Library HP E1432A Parameters Some parameters such as range or coupling apply to specific channels When a channel ID is given to a function that sets a

IDs which are created by a call to el432 assign channel numbers The 1432 assign channel numbers function must be called exactly once following the call to 1432 init io driver in order to declare to the library the logical addresses of the HP E1432A modules that will be used This function checks the existence of an HP E1432A module at each of the logical addresses given in a list of logical addresses and allocates logical channel identifiers for each channel in all of the HP 1432 5 Input channels source channels and tach trigger channels are kept logically separated Channel numbers for each type of channel are numbered starting from one so there will be input channels 1 through M source channels 1 through N and tach trigger channels 1 through P where M is the number of input channels N is the number of source channels and P is the number of tach trigger channels As an example suppose two logical addresses 100 and 101 are passed to the function and the logical address 100 has two 4 channel input SCAs and a 2 channel tach trigger board while logical address 101 has three 4 channel input SCAs and a 1 channel source board In this case input channel IDs 1 through 8 are assigned to the eight input channels at logical address 100 while input channel IDs 9 through 20 are assigned to the twelve input channels at logical address 101 Tach trigger channel IDs number 1 and 2 are assigned to the two tach trigger channels at logical add
69. Interrupt Handling When the HP E1432A asserts the VME interrupt line the program will cause the specified interrupt handler to get called Typically the interrupt handler routine will read data from the module and then re enable HP 1432 interrupts with hpel492 reenableInterrupt call to hpel432 reenableInterrupt must be done unless the host is not interested in any more interrupts Inside the interrupt handler almost any HP E1432A Host Interface library function can be called This works because the Host Interface library disables interrupts around critical sections of code ensuring that communication with the HP 1432 module stays consistent Things that are not valid in the handler are 3 90 HP E1432A User s Guide Using the HP E1432A Calling hpel492 createChannelGroup to delete a group that is simultaneously being used by non interrupt handler code Calling one of the read data functions hpel432_readRawData or hpel432 readFloat 4Data if the non interrupt handler code is also calling one of these functions Calling hpel452 init to reset the list of channels that are available to the HP 14 2 library As is always the case with interrupt handlers it is easy to introduce bugs into your program and generally hard to track down these bugs Be careful when writing this function Data Gating Sometimes you may wish to monitor data from some input channels and not others The function hpel1432 setEnab

This places a limit on how far in time the host can be behind the data acquisition By setting the size of the FIFO is you can control how far behind the host can get Making Overlap Block Mode Act Like Traditional Block Mode If the FIFO size is set the same as the block size or if the number of pending triggers is limited to zero then overlap block mode becomes identical to traditional block mode Making Overlap Block Act Like Continuous Mode If the module is in auto arm and auto trigger mode then overlap block mode becomes nearly the same as continuous mode One difference is that traditional continuous mode has a single arm and trigger while overlap block mode may have multiple arms and triggers Another is that continuous mode can be configured to start at any type of trigger event while overlap block mode must be in auto trigger mode to act like continuous mode Finally continuous mode always stops when a FIFO overflow occurs but overlap block mode does not 3 28 HP E1432A User s Guide Using the HP E1432A HP E1432A Interrupt Behavior Interrupt Setup For an example of interrupt handling see the program event c in the examples directory The HP E1432A VXI module can be programmed to interrupt a host computer using the VME interrupt lines VME provides seven such lines Using hpel1432 setInterruptPriority you can set up the HP E1432A module to use any one of them The HP 1432A can interrupt the host computer in
