Getting started

To use the STEVAL-IME003V1, perform the following steps:

Connect the power supply to the board (see Section 3.1).

Connect the BNC to the oscilloscope.

Check that switch SW1 is set to the FPGA position.

Check that the LED indicator DONE (D23) turns on.

Check that FPGA is in the idle state (LED D4 is on).

Select the waveform with the PROGRAM button. The corresponding program LED

(D6-D29) turns on.

Press the START button to run the selected program; the START LED (D2) turns on.

After the program ends, the FPGA returns to the idle state (LED D4 is on).

If a continuous wave program has been selected (Program “2”), the STOP button must

be pressed to stop program execution. The FPGA returns to the idle state and the

STOP LED (D3) turns on.

To run the same program again, restart from step 7. To run a different program, restart

from step 6.

Programming waveform description, flagged by LED (D6-D9)

Program “0” (see Figure 2)

–

XDCR_A: pulse wave mode, TX0 switching, 5 pulses, time-period TP=400 ns and

PRF=150 µs

–

XDCR_B: pulse wave mode, TX0 switching, 5 pulses in counter phase respect to

XDCR_A, time-period TP=400 ns and PRF=150 µs

–

XDCR_C: pulse wave mode, TX1 switching, 5 pulses, time-period TP=200 ns and

PRF=150 µs

–

XDCR_D: pulse wave mode, TX1 switching, 5 pulses in counter phase respect to

XDCR_C, time-period TP=200 ns and PRF=150 µs

Note:

TX0 means H-bridge supplied by HVP/M0, while TX1 means H-bridge supplied by HVP/M1.
