EVM430-FR6047: How to configure in Ultrasonic Design Center. ( EVM430-FR6047 )

Hi,

Do you have any update?

Best Regards

Hi Koki,

Q1: I think you can set the USS_F1_FREQ as you want in the USS_userConfig.h file instead of setting the F1 frequency through the GUI

Q2: You can't use the GUI function when you set below 780kHz

Q3: You can set even number pulses as you want. The increment way does not influence anything.

Q4: Yes. HSPLL frequency = ADC over sampling rate * Signal sampling frequency. The HSPLL is 68MHz ~ 80 MHz.

Hi, Cash Hao

Thank you for your reply.

> Q3: You can set even number pulses as you want. The increment way does not influence anything.

I would like to know the specific procedure for setting even number pulses.

Hi Kiko,

Input the number with your keyboard.

Hi,

Cash Hao

Thank you, I solved this problem.

But I want to know one more about Q1.

>Q1: I think you can set the USS_F1_FREQ as you want in the USS_userConfig.h file instead of setting the F1 frequency >through the GUI.

I want to set the transmit frequency to 210kHz and check the waveform the on Design Center.

1. Set USS_F1_FREQ to 210000 in USS_userConfig.h file. (line174)

Before : #define USS_F1_FREQ 1000000

After : #define USS_F1_FREQ 210000

2. Set transFreq to 210000 in USSLibGUIApp\fr6047_USS_app\hmiDC\hmi.c (line759)

Before : transFreq = DC_User_Params->transFreq1;

After : transFreq = 210000;

3. Write the project whose settings have been changed in CCS.

4. In Ultrasonic Sensing Desingn Center, configures the parameter.

Configuration→Parameters： Software Parameters

・Transmit frequency(kHz) = 780（Minimum）
・Gap between pulse start and ADC capture (µs) = 40
・Number of Pulses = 7
・UPS and DNS Gap (µs) = 500
・UPS0 to UPS1 Gap (ms) = 50
・GUI Based Gain Control = 1.0db

5. Press the "Request Update" button.

6. "Configuration Update successful" is displayed.

After procedure 1~6, I check the waveform on EVM.

*Currently, waveform confirmation is performed on the signal line of the sensor.

I checked transmitted wave is output at a frequency of 780kHz and 7 pulses according to the GUI settings.
When I changed Transmit frequency (kHz) = 1000 Number of Pulses = 1 in GUI , I checked transmit frequency is 1MHz and the output is 1 pulse.
⇒ However, transmit frequency is not 210kHz.
It seems that procedure 1,2 are not reflected.

Please tell me how to set transmit frequency = 210kHz and check the waveform at the Design Center.

Best regards,

Koki
