DXP is a program for controlling 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
DAC8832. Straight dc outputs can also be obtained.

Hardware
The hardware consists of two primary components: the DAC8832EVM 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.
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 DAC8832EVM is plugged onto the MMB0 aligning female
connectors J4, J2 and J6 (on the bottom side of the DAC8832VM) with male connectors J7, J4 and J5 on
the MMB0. The assembled hardware is shown in
