EVM430-FR6047: ADC Capture of USS doesn't work in high values of the Gap between Pulse Start and ADC Capture (us).

Part Number: EVM430-FR6047

Tool/software:


I have an EVM430-FR6047 Board. In the user guide of USS software, the Gap between Pulse Start and ADC Capture (us) has a range of 3 to 9000 uS. But I can only set a minimum of 30 uS and a maximum of 2,648 uS practically. How can I increase the range, especially the maximum value of the parameter? When I increase the Gap between Pulse Start and ADC Capture, ADC capture doesn't work. When I decrease the value to lower than 2648, it works again. Start PPG Count (ns) and Turn on ADC Count (ns) parameters have their default values of 10,000 and 5,000 respectively.
Best regards

    Hi,

    Emm, interesting topic. I never tried to set a larger Gap between Pulse Start and ADC Capture before. If the GUI can not set the parameter correctly, I would suggest you to directly change this value in the project. And then program the project into the EVM board. 

    It is USS_START_CAPTURE_SEC in USS_userConfig.h file. 

    Best regards,

    Cash Hao
