Zeta
This product is supported for DSCUD 8.0 and above.
Overview
The Zeta COM Express SBC family of ultra-small embedded computer boards combines a COM Express Mini CPU module mounted on a same-size carrier board to create a complete embedded PC. Zeta integrates onboard memory, one PCIe/MiniCard socket, dual Gigabit Ethernet, and optional data acquisition circuit with analog and digital I/O.
The SBC provides an optional data acquisition circuit containing analog input, analog output, and additional digital I/O features. This circuit is controlled by an FPGA interfaced to the processor via LPC.
Board Initialization
To use the Zeta board in an appllication using the UD, the dscInitBoard function should use the board macro DSC_ZETA. This is shown in the example below.
The base address should be 0x200 and the default IRQ to use is IRQ 5.
