Tips for troubleshooting and asking questions

marao | 08/227/2019 | 08:46 PM
Before posting a question
1. Apply basic troubleshooting:
  
  Check hardware connections with multimeter.
  
  Use logic analyzers/oscilloscopes.
  
  Use Simplicity Studio Debugger/Energy Profiler
2. Search the forum to see if someone has asked the same question already.
3. Consult the datasheets, reference manuals, application notes and user guides. Sources include:
  
  Simplicity Studio Launcher Documentation Tab
  
  32-bit Knowledge Base Article List
  
  Silicon Labs Technical Resource Search
When posting a question, make sure to include the following:
1. Provide detailed information about the issue.
2. Include the relevant parts of your development setup in the problem description. Examples include:
  
  SDK version
  
  Emlib version (found at the top of any em_*.c file)
  
  Part number
  
  Identify if using a Silicon Labs Evaluation Board or a custom board
  
  Compiler and compiler version
3. Identify the expected behavior
4. Identify the observed unexpected behavior, and provide step-by-step, detailed instructions on how to reproduce
  
  Provide operating conditions such as voltage, temperature, etc.
  
  Provide any relevant scope or logic analyzer captures of the unexpected behavior
For general community usage please refer to the Silicon Labs Community Guidelines.

New 32-bit peripheral example projects on GitHub (Updated 5/24/2019)

BrianL | 01/23/2018 | 10:31 PM

We've been working here to create a few more examples for EFM32/EFR32 devices that show basic examples of how to operate the device's peripherals. If you're familiar with our EFM8/C8051 examples, this is a similar setup. Basically, each peripheral (adc, gpio, i2c, etc) has a set of bare-bones examples that demonstrate some operation mode of the peripheral. Not all peripherals or modes are currently covered, but we will be adding more in the future.

The repo can be found here: https://github.com/SiliconLabs/peripheral_examples

Edit 8/27/18: We've pushed a ton of new examples - check it out!

Edit 3/12/19: We are migrating our discussion, questions, and bug reports for the 32-bit peripheral examples to the Issues section of the Github repository. This will allow us to track bugs and feature requests more easily.

Edit 5/24/2019: We've added Series 2 examples, as well as cleaned up the repo structure.

How to check if CDC driver is installed?

Tomáš Petr | 10/276/2019 | 12:52 AM

I need to install silabs cdc driver to client computer so my application works correctly. How I can check, if the driver is already installed on his computer? After opening the installer, it just says "Silicon Laboratories. Inc. (usbser) Ports (03/26/2014 6.1.7601.17514) - Ready to use" and that's it. In windows 8-10this com port drivers should be pre-installed, but what about the other versions?

I tried to search for "usbser.sys" in list of drivers, but nothing found. And I also tried to search for "USB\VID_1BA4&PID_0002" and others from .inf file, but also nothing. I tried also search in regedit for "4D36E978-E325-11CE-BFC1-08002BE10318" ClassGUID, and class=ports, but it's the same result in every computer with windows, so that's probably not what I'm looking for.

How the driver detect it itself? Thanks for any informations!
