| Abstract: | Through PXI9030 and two ST16C554 chips, the multi-serial port card based on PXI bus can realize the interconnection between PXI bus MACSYM and eight serial peripheral devices. The hardware of the card consists of PXI bus interface, CPLD and multi-serial port ST16C554 circuits. The driver is. realized by DLL. The DLL finishes the initialization of the device and ST16C554, port-reading and port-writing and the setting and response of the serial interruption. |
