Local Bus Data Transfers
The following programs demonstrate:
• how readings are transferred over the Local bus from a single
digitizer to the HP E1488 memory card (LOCAL_AD.C)
• how readings in digitizer memory are transferred over the Local bus
from two digitizers to the HP E1488 memory card (LBUS2PST.C)
• how readings from two digitizer A/Ds are transferred over the Local
bus to the HP E1488 memory card (LBUSAUTO.C)
For completeness, the entire C language versions of these programs are
listed. The programs are also contained on the example programs disk
(HP p/n E1429-10302).
LOCAL_AD.C This program transfers readings from both digitizer channels to the
HP E1488 memory card. The readings are tranferred directly from the
digitizer A/Ds.
