HC-SR04 connection to particle argon
#nrf52480
Smitha Ratnam <s.ratnam@...>
I need to connect the HC-SR04 ultrasonic sensor to the particle argon board and use it for distance measurement with Zephyr.
What is the device binding that needs to be done in zephyr for this?
Are there any zephyr samples that can help? Thanks and regards, Smitha.

Hi Gunnar,

We got the PLL2 code into the STM32CubeF1 codebase a little while ago [1]. There are also some patches for adding this support into Zephyr, but I need to revisit them / make a PR now that the PLL2 support was merged into STM32CubeF1... [2][3][4]. I hope that helps!

Hi Gunnar, Unfortunately, we miss code for PLL2 configuration as PLL input. Though, I'm adding Attie who investigated that point and may have code to get it working. BR Erwan

STM32F107 clocks
Gunnar Bråding
Hi!
I got a board with the crystal at 25MHz, and need to use the PLL2 as input to the system clock. I just do not seem to understand the code enough to see how to set the prediv and multiplication for the PLL2 I can choose PLL2 as input to the PLL, and PLL as input to the system clock, but how do set the parameters for PLL2? Any pointers would be very much appreciated. Cheers, — Gunnar

Bluetooth support for Silicon Labs EFR32XX
chzfmx@163.com <chzfmx@...>
Hi ,
My zephyr version is 2.5.0, and the board is EFR32_radio_brd4180a from Silicon Labs. When I try to compile and run the Bluetooth routine (samples/blutooth/peripheral_hr), the serial port prints: "Bluetooth init failed (err -19) , No HCI driver regsitered", and then I retrieved Issues#17005: https://github.com/zephyrproject-rtos/zephyr/issues/17005 . The conclusion is that it is almost difficult to provide Bluetooth support for Silicon Labs chips unless they provide library or register descriptions, so I would like to ask if there are any new developments or plans for the future.Thanks! chzfmx@...

brushless motor / servo driver in zephyr ?
popeye22202
Is there any brushless motor / servo drivers in zephyr ?
FYI, I've noticed various brushless software, such as : http://vesc-project.com : ChibiOS based. Mostly motor code (originally for skateboards), but added "VESCular6" servo code recently. https://github.com/mjbots/moteus . mbed-os based. Mostly servo / actuator code for robots, but he added motor code recently. http://simplefoc.com : Arduino based. I've been tinkering w/ a stm32 eval kit : P-NUCLEO-IHM001 with the ST motor sdk, but I'd like to use Zephyr. Thanks !

Hello.
Are there any more specifics than provided in https://docs.zephyrproject.org/latest/guides/portability/index.html to be able use the CMSIS RTOS v2 (or V1) in Zephyr OS? When enabled does it disable/replace the Zephyr OS kernel? Also, is my understanding correct that the CMSIS would have to be treated as a Module (external project)? That this is ARM specific only? Is there a reference implementation that shows how the KConfig/yaml/CMakefiles are setup?

Hello:
I was wondering if the community could help me with using SystemView with Zephyr.
When I connect to the board using JLink and then try to record with Systemview, I get a message telling me that the RTT control block was not detected. If I force the call to SEGGER_SYSVIEW_Start() by either setting CONFIG_SEGGER_SYSTEMVIEW_BOOT_ENABLE=y or by putting it in my main function, what I get instead is a message to the effect that it can't find the SystemView buffer.
I believe I've been following the instructions correctly as outlined here:
https://docs.zephyrproject.org/2.4.0/guides/debugging/probes.html?highlight=segger.
and here
https://docs.zephyrproject.org/1.9.0/samples/subsys/debug/sysview/README.html
I am using Zephyr 2.4.9 with the 0.11.4 SDK on Ubuntu 20.4.
For the image, I am using the hello_world example and adding the following to the prj.conf file:
CONFIG_TRACING=y CONFIG_SEGGER_SYSTEMVIEW=y CONFIG_THREAD_NAME=y CONFIG_USE_SEGGER_RTT=y CONFIG_SEGGER_SYSTEMVIEW_BOOT_ENABLE=y CONFIG_STDOUT_CONSOLE=y
It's interesting to note that JLink itself appears to connect just fine:

I am working on a Nucleo-L496ZG board, but the same thing happens on a Nucleo-F429Zi or a Nucleo-L4R5zi. I am following the SEGGER instructions to flash the onboard ST-Links with JLink firmware, which appears to work fine.

Re: custom board
#customboard

The Kconfig.defconfig doesn’t look right
config BOARD default "fuse board"
I think it should be “fuseboard” or maybe “fuse_board” but I didn’t test it. I looked at every other board name in the zephyr tree and none have a space in the default.
