Using the DAC8581EVM with DXP
The DAC8581EVM is compatible with the
from Texas Instruments. DXP is
a tool that can generate the necessary control signals required to output various signals and waveforms
from the device installed on the DAC8581EVM. The DAC8581EVM-PDK kit combines the DAC8581EVM
board with the DSP-based MMB0 modular motherboard. The kit includes the DXP software for evaluation
using any available USB port on a Microsoft
®
Windows
®
XP-based computer.
DXP is a program that controls the digital input signals such as the clock, CS, and SDI. Wave tables are
built into the DSP software to allow sine, ramp, triangle, and square wave signals to be generated by the
DAC8581. Straight dc outputs can also be obtained.
The DAC8581EVM-PDK uses the DSP-based MMB0 to control the DAC8581EVM using the DXP
software. For complete information about installing and configuring DXP, see the
available for download from the
. This section covers the specific operation of the
DAC8581EVM-PDK.
4.1
Hardware
The hardware consists of two primary components: the DAC8581EVM itself and a modular motherboard
called the MMB0. The MMB0 board houses a TMS320VC5507 DSP that controls the serial interface to the
device loaded on the EVM board.
The hardware must be configured such that the DAC8581EVM is plugged onto the MMB0, aligning female
connectors J4, J2, and J6 (on the bottom side of the DAC8581EVM) with male connectors J7, J4, and J5
on the MMB0. The assembled hardware is shown in
CAUTION
Be sure to exercise caution when assembling the boards. It is possible to
misalign the connectors and damage both the EVM and the motherboard.
