TSW14J56EVM: TSW14J56evm

Part Number: TSW14J56EVM
Other Parts Discussed in Thread: ADS54J60, ADS54J60EVM

Hi,

I have two queries:-

1) If I need two or more TSW14J56evms to run parallelly, do I need to just enable the trigger option in the HSDC software, or Is there some other code I need to change as well? And If I just need to enable the trigger option, then how can I capture the data if I want to provide the trigger again and again. Changing the settings everytime is not a viable option here. 

2) I get the Clock message everytime I set the Sampling Rate; I have set ADS54J60_8224 device; clock- 983.04M (in ADSevm GUI); 8MHz input freq; 1.9Vpp; 50 ohms load. Can you tell me why am I receiving this message?

Thanks,

Raeleen

    Raeleen,

    1. To capture simultaneously with multiple TSW14J56 EVMs, see section 3.1.3.4 of the HSDC Pro GUI user guide. Additionally, to avoid changing the settings every time as you mention, you will find the function "Auto Re-Arm Trigger" in the latest HSDC Pro GUI under Trigger Option. See the attached file for more info regarding this.

    2. This is just an informative message and can be ignored.

    I have connected two TSW boards using master slave option only as given in Section  3.1.3.4. Currently, I am using the TSW14J56 boards in Sysref-Based Master Slave Triggering mode.

    1) Now, for enabling simultaneous trigger for both the master and slave, how should I proceed with that? 

    2) Can I also automate the whole simultaneous master slave trigger. Can you help me with the code for that?

    3) Also, Is it possible to add new functions like waveform math etc to the HSDC GUI (to increase flexibility and scalability).

    For the second question, I am attaching the code file. Can you tell me why isn't it working on the hardware?https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/73/8054.trigger.m

    Hi Raeleen, we are working on this for you.

    1) I will verify the dual TSW14J56 setup for you and have a response soon.

    2) I am asking our team for assistance on this.

    3) There are no intentions of providing math functions in HSDC GUI.

    Regards, Chase

    Hi Raeleen,

    Can you please try "Software trigger" instead of "Arm on the next capture" for the Master board and use the “Generate_Software_Trigger” automation function to generate the trigger?

    In the Matlab code which was shared, selecting an ADC INI is sufficient. Reload_Device_INI is used when there are any changes done to the INI parameters using HSDC Pro and you want to reload it back.

    Can you also guide me on this.

    While capturing, I am using TSW14J56evm + ADS54J60evm (16 bit ADC).

    so, on HSDC it should be able to capture values from -2^16-1 to +2^16-1 (for 65536 samples).

    But I am just getting maximum value till 3000.

    Can you help me with it?

    Hi Raeleen,

    For a 16-bit ADC, codes will be in the range of -2^15+1 to 2^15-1.

    When I plot this data, I get the following. I do not see anything at a maximum until 3000. Could you perhaps rephrase this question for me?

    Regards
