Why is 'Sensor' a Peripheral in the API Reference?

Jennifer M Williams
 

Hi all,

 

What is the rationale for ‘Sensors’ being under ‘Peripherals’ in the API Reference with the ADC, Counter, I2C, SPI, etc.?  Is it because the Peripheral APIs are for hardware-related interface?

 

Thanks,

Jen
Re: west 0.6.0rc1

I forgot to add: it would be nice if any issues could be reported via the west bug tracker (https://github.com/zephyrproject-rtos/west/issues) rather than email, if possible. Thanks again.

Subject: west 0.6.0rc1

 

Hi,

 

West version 0.6.0rc1 has been tagged. Release notes are in this pull request:

 

https://github.com/zephyrproject-rtos/zephyr/pull/17714

 

Testing and feedback are welcome; I’d like this to be the minimum version for Zephyr 2.0. To install this RC, use “pip3 install west==0.6.0rc1” (and pip3 install --user on Linux as usual).

 

You can “pip3 uninstall west” then “pip3 install west” (without the version specifier) to go back to v0.5.8.

 

Thanks!

Marti

feedback on driver-specific API architecture

Peter A. Bigot
 

As discussed in various meetings: there is an ongoing need for Zephyr to support peripherals that have features beyond what is supported in the generic driver class, e.g. calibration APIs for specific sensors.

https://github.com/zephyrproject-rtos/zephyr/pull/17072 discusses the general case with a stub API.

https://github.com/zephyrproject-rtos/zephyr/pull/17631 provides a specific case with a complete API.

Feedback on the overall approach is requested, and may be provided on either PR; 17072 should have less clutter related to the details of the Maxim RTC chip that it supports.

New DT parser and code generation

Kumar Gala
 

All,

Just a heads up on some changes to the generation path for handling of DT.

Ulf and I have been working on a replacement for the DT parsing and Code Generation code. The replacement is in this PR:

https://github.com/zephyrproject-rtos/zephyr/pull/17660

The intent is to deprecate the old code (scripts/dts/devicetree.py, scripts/dts/extract_dts_includes.py and scripts/dts/extract/). The old code will stay around for a little while to generate the deprecated macro’s.

The new code is structured in 3 pieces:
* dtlib.py - DTS parser
* edtlib.py - Semantic Device model
* gen_defines.py - Code generator

The intent is to keep the (dtlib.py and edtlib.py) agnostic of Zephyr, and have all the Zephyr specific details in gen_defines.py.

Hi, 


Thank you for your help. I have tried the commands given in the documentation and yours as well. My Python Version Python 2.7.15+. I am getting the following errors after executing the commands in Zephyr Example of NRF52840_PCA10059 Dongle.

FYI, I am just pasting the commands and the errors.


Command 1:

Error 1:

Command 2:

THE ABOVE COMMANDS ARE GIVING SAME ERRORS AS MENTIONED IN THE PREVIOUS EMAIL.

Hi there,

 

Can you try this instead:

 

~/zephyrproject/zephyr$ west -v build -b nrf52840_pca10059 samples/basic/blinky

 

Then you can find the build output files in the build/ folder.

The syntax of the west build command is well documented both in the tool itself and in the documentation here:

Welcome to the Zephyr Project! We're so happy to hear you are exploring ZephyrOS and Bluetooth Mesh. I'm happy to help you through the process of getting started with your first application. Have you joined the Slack channel? Its a great place to ask questions and get to know the community better. A number of our experts in Bluetooth Mesh are on daily. Everyone is always happy to help. 

 

My favorite place to get started is the Bluetooth section of the documentation guide. I have also personally found the Bluetooth Mesh Study Guide incredibly useful. Its produced by the Bluetooth SIG and is a great resource for getting a deeper understanding of the ins and outs of the technology. You may also find this presentations useful.  

 

If those guides do not answer your questions or if you already went through the guides and still have questions, please feel free to reach out to me at any time. I am always happy to help where I can.

Re: One Questions about ZephyrOS

Wang, Steven L <steven.l.wang@...>
 

Hi Rockc:

   Essentially, app code and kernel code will be combined into one image. Then that image will be flashed into target board.  There is no support for program loader.

   Actually, in zephyr app development, all app code are usually put into a directory outside of the Zephyr base directory. With this way, engineer can focus on app code and don't need to touch any kernel code.

Hi, Jennifer,

Thanks for the reply. I have a quick scan of the get-started-guide. 

I do not see elf-loader support on Zephyr OS, as I know uClinux , NuttX can support it. Beacuse our application engineers want to have a standrad development enviroment and they can only stay focus on application layer like Linux does, is this maybe possible for Zephyr?

Mesh Proxy node communication with PC #bluetoothmesh

paul.leguennec@...
 

Hello,

I am trying to send my mesh message from my proxy (that receive the message from my network) to my PC. I've understood that to do so, I should be using Mesh Proxy Data Out to notify my PC (GATT Client). Yet, I have some trouble finding how to do it. Should I implement GATT functions in my proxy node (as in the reel_bord/mesh_badge example). And if yes, how do I know that I am writing my message in the Proxy Data Out notification ?

Thanks for your response,

Hi Muhammad,

it seems like you are depending on python 3.6 - I don't have my env on the machine I'm using right now, but seem to remember you need python 2 (I might be wrong)

west build -b nrf52840_pca10059 zephyr/samples/basic/blinky
Now this step is going smoothly..
The second step ( 
nrfutil pkg generate --hw-version 52 --sd-req=0x00 \

Re: [EXT] [Zephyr-devel] Help flashing nxp MIMXRT1050-EVKB

Hello Flavio,

From what you describe, most probably you have an old version of SEGGER JLink on your host machine. I have the following version on my machine:
SEGGER J-Link Commander V6.46c (Compiled Jun 3 2019 18:32:22)
DLL version V6.46c, compiled Jun 3 2019 18:31:31
Please check your host's version of JLink (e.g. JLinkExe - Linux/ JLink Commander - Windows)

There maybe other issues such as:
- debugger FW (looks like you use a generic firmware, there is a board and hyperflash specific version of the firmware)
- dip switches on board

Regards,
Andrei Gansari

Caution: EXT Email

I'm trying to flash this board following our documentation with no success. I've being installed the OpenSDA_V2_1.bin firmware but when I try to flash I get the following error:

J-Link connection not established yet but required for command.
Connecting to J-Link via USB...O.K.
Firmware: J-Link OpenSDA 2 compiled May 27 2019 11:01:03 Hardware version: V1.00

VTref=3.300V
Target connection not established yet but required for command.
The selected device "MCIMXRT1052" is unknown to this version of the J-Link software.

I've tried both, stable and beta J-Link tools. Someone have seen or know how to fix problem ?

Hi Muhammad,

I have an example project that needs a few changes to be compatible with the latest master (was using 1.14-rc) - but maybe it can be used for inspiration:

Hi Muhammad


I doubt anyone here can give you a better general write up then the documentation. So you need to provide information about the specific problem.

  • Which exact instructions are you following
  • What is your operating System and Toolchain
  • Which version of Zephyr are you running
  • Which steps are unclear / make you problems
  • Where does it fail? What is the error output.
  • Additional information

Best regards
