EFM32ZG Sensor-Puck connection...

RWReynolds

Ok, has anyone else tried to work with the SensorPuck.

 

I have the Sensor-Puck connected to the EFM32ZG. And I've managed to configure Simplicity to recognize the puck for debugging. But there is no example software for the puck and I can't seem to locate the correct source code for the sensor-puck at SL. I found a link that says it's for the source code for the Sensor Puck firmware, V1.0. But I can't get it to compile. Missing includes and such. I found versions of some of the files but i wouldn't be willing to burn the image even if I could get it to compile.

It's at the very bottom of this page.

Sensor Software | Silicon Labs

 

And if I can get it compiled or not, can I read it from the J-TAG - I/O header if ti's in I/O mode. Not really finding any docs on that.

 

Any help appreciated.

 

Cheers,

Rick

    Hi Rick,

     

    The sensor puck works out of the box with android (and IOS too I guess) if the app is downloaded. If you wanted it to work with (say) raspberry pi or beaglebone black then a Bluetooth LE to USB adapter could be used.

     

    As I understand, you're trying to connect it directly to one of the Silicon Labs boards, right? I need to check, but personally I think a good way to do that may be to avoid the sensor puck's microcontroller and directly connect to the I2C connection on the sensor puck (cutting any tracks where needed). I suggest that because your primary concern are the sensors, not the microcontroller on the sensor puck, if you are not using the Bluetooth LE functionality. I'm on a mobile device but will check the layout and schematics in more detail when I'm near a PC tomorrow.

    Thanks for the reply Sahabaz...

     

    Yeah, at about 41:00 on the webinar video from the Vertical Farming Challenge front page Matt Saunders from SI Labs gives a short tutorial on how to connect the puck to the EFM32ZG. Mainly so you can program the EFM32G210 micro on the puck. You're supposed to be able to get the original source code that comes on the puck and import it into SimplicityStudio. I got the devices connected and configured SimplicityStudio to recognize the puck's micro. But I can't find any source code that I trust. I don't want to brick the puck.

     

    I don't really care so much about the smartphone apps. They're cool and a good way to test the device. But I'd like to see if I can connect the puck to the EZR32WG via the JTAG connector, should be similar to the EFM32ZG. The JTAG on the EFM32ZG can be configured as a serial I/O device. I want ton know if the puck can do the same. Then you could read all the sensors and use them for feedback on the EZR32WG for control. Also, if you had the source code you could see exactly the message protocol between the puck and the smartphone app. Then you could easily use the BLE for a Pi or something else. That would be interesting as well.

     

    I just need reliable puck source code and to know about the JTAG connector on the puck and can it be used for I/O like the EFM32ZG.
