Original question:

TMP118EVM: USB Command Driver

TMP118EVM: Source Code for TMP118EVM GUI

Part Number: TMP118EVM
Other Parts Discussed in Thread: USB2ANY, TMP119EVM

Tool/software:

Hello,

Would it be possible to share the source code for the TMP118EVM GUI for Windows? I would like to modify the code so that I can have multiple TMP118EVM eval boards connected to a USB hub on my PC and log data from multiple sensors. We plan on using these eval boards for testing our design and verifying temperature rises.

Thanks

    Hello Joe,

    If the goal is to evaluate multiple sensors on multiple EVM boards (I assume one sensor per board), you can either use multiple EVMs and have multiple instances of the GUI opened in your browser or (preferrably) utilize an I2C controller you can control and evaluate all sensors in one interface.

    The GUI source code itself is readily available by opening the console in your browser (Ctrl+U) while on the GUI webpage.


    Regards,

    Thanks Harry - I received two of the TMP119EVM boards and tried out the web browser application. I was able to get them both to run at the same time, but I had to make sure the Options > Serial Port Settings... > Port: was pointing to different USB2ANY devices. I did notice that there was some contention between them at first and I had to reload one or both webpages in order to get them connected and streaming data at the same time. I also noticed red X marks on one of the browsers. Do you know what the red X's mean? When I hover over the Device Rate one, for example, the help message says "usb2any error: missing response for command sequence #19". I'm assuming that maybe there is contention in communication to the eval board on this browser, and the settings may or may not have actually taken into the registers of the sensor? Data is still streaming from this sensor though. Please see attached image for reference. Thanks

    Joe,

    Let me test this out on my setup and will get back to you tomorrow.

    Hello Joe,


    Have you tried refreshing the web browser page? When I had two EVMs connected simultaneously I noticed one of them stopped working after the additional EVM was connected. The software occasionally needs to be reset when using multiple EVMs and it should resume function afterwards.


    Regards,

    Thanks Harry - I can get the two working without the red X circles by refreshing like you suggested. It took a few tries but ultimately I got it working. I'll mark this as resolved. Thanks for your help!
