Hi Henry: If you are just trying to understand how the sensor_sample_fetch() call works you can look at an example program that works with a

Hi, Please read: https://docs.zephyrproject.org/latest/kernel/usermode/syscalls.html Hope this helps!

Hi folks, I have a problem understanding how system call work. For example, system call /*fetch sensor samples */ rc=sensor_sample_fetch(dev); But I only see definition: __syscall int

TCS Confidential Dear Team, I am new to Zephyr and started working now. I wanted to to Port new device driver I2C to Zephyr OS and run sample application sensor TMP112 for specific custom hardware

The best way I've thought of neopixel (aka ws2812) timing is that its a 800 khz signal with 1/3 and 2/3 duty cycle. On ESP chips, the RMT peripheral is generally the best way to produce it. Here is

Hi: The following blog post is an excellent resource about pulse timing: https://wp.josh.com/2014/05/13/ws2812-neopixels-are-not-so-finicky-once-you-get-to-know-them/ You'll need to hook up a logic

Dear all, I am trying to run Zephyr sample ./zephyr/samples/drivers/led_ws2812/README.rst on chipset ESP32c3. After some tuning of this example, I am able to run it, diodes starts to flash one by

Hi Team, I am trying to enable https on zephyr system as i dont have file system on board i passed certificate and key in array format and passed it to init_ssl() callback but function not getting

Hi, thanks for the hints. I've looked into newlib and picolib but found no way to do it since the functions used in the Zephyr tests `tzset()` and `setenv()` are not supported by Zephyr according to

Hi! I'm trying to verify a "reset_n" gpio with Twister, using board = native_posix. The behavior is to make reset_n low for 1 ms and then set it high again. The driver

Hello Robert, thanks a lot for the prompt reply! Adding 'CONFIG_NET_SOCKETS_OFFLOAD=n' did the trick and have managed to connect 🎉 ... *** Booting Zephyr OS build zephyr-v3.2.0-3154-g3c4783042eed

Hi, The Wi-Fi driver you use implements socket functions on its own (i. e. uses socket offloading feature), but the implementation seems to be incomplete. Generally, it fails when the LwM2M lib

Hello all, I am experimenting with the LwM2M client example on a B-L475E-IOT01A board. Based on the lwm2m example that comes with Zephyr I have modified it and added code that initializes the Wi-Fi

Good Day, I am very new to Zephyr RTOS, as in I've set up the environment and have loaded sample files and flashed them to my pinnacle 100 DVK. It turns out that I need to write a driver for

Hi there, Zephyr supports both newlib and picolibc, which are fully-featured C standard libraries. Unless I am mistaken timezone-conversion functions are part of the C standard library

Hi, I've got a question concerning time zone support: Does Zephyr provide any functions for converting UTC to other time zones? I have not found anything about it in the docs aside from the standard

I used it in the past to do some smart devices at home but programming the nrf24 micro with Arduino IDE (maybe 8 years ago) instead of using it as a modem, maybe that's the difference. I'll keep

Hmm...the NRF24L01 is a proprietary 2.4Ghz radio but doesn't implement wi-fi as far as I know.

Hi Jonathan, I'm using the latest release version ESP32-WROOM-32-V2.4.0.0. I'll continue investigating the issue. Do you know if there's support for NRF24L01 devices to use them as WiFi modems over

I haven't tried this myself but make sure you check which release of the esp32-at your device is running. It also seems that the ESP32-S2 is no longer supported:
