275. TSCH@Zephyr: IEEE 802.15.4 SubG IIoT in the Making

Chris Friedt (Meta)

11/15/23, 3:10 PM

Zephyr's native IEEE 802.15.4 L2 is a hidden treasure: It supports a much larger variety of SoCs, vendors and PHYs than its more popular OpenThread counterpart. Native L2 not only runs the common 2.4G O-QPSK modulation but also has rich SubG support on all regional bands, from legacy BPSK all the way to SUN O-QPSK, FSK and OFDM and even initial support for HRP UWB. The latter is increasingly...

322. Zephyr Retro-and-Prospective: Project Growth, Long Term Support, and Linux Interoperability

Chris Friedt (Meta)

11/15/23, 3:50 PM

Zephyr has been a part of the Linux Plumbers IoT Microconference since [the first year in 2019][1]. Needless to say, much has happened in that short period of time.

[Increasingly more devices][2] are shipping with Zephyr. More companies are becoming [members][3]. More devices and are compatible out-of-the-box with Linux (and macOS, and Windows). The Internet of Things is made of devices...

281. Shared FPU Support in Zephyr for ARM64 and RISC-V

Nicolas Pitre (BayLibre)

11/15/23, 4:30 PM

Computers are good at doing computations, obviously. But this is not that simple when floating point numbers are involved. Many processors implement a dedicated floating point unit (FPU) to perform computations on such numbers much faster compared to using the regular arithmetic logic unit (ALU).

FPU usage is not free though, especially when an operating system is involved whose purpose is...

277. Challenges in Device Tree Sync - kernel, Zephyr, U-boot, System DT

Nishanth Menon (Texas Instruments, Inc)

11/15/23, 5:05 PM

The description of hardware through Device Tree, which includes Firmware in some instances, has become an increasingly common practice in many software ecosystems. However, despite various efforts, the device tree description of hardware has yet to be standardized across different software ecosystems, creating challenges for users, automated tools, and ecosystems.

The objective of this...

160. Breaking Barriers: Arduino Core API advancements in Zephyr, Linux and IoT Systems

Dhruva Gole

11/15/23, 5:40 PM

This presentation will provide an overview of the Arduino Core API and Zephyr RTOS, and explain how their integration can simplify and streamline IoT development. We will cover the advantages of using the Arduino programming model with Zephyr, and how it can benefit developers by providing access to a wide range of pre-built functions and modules. The presentation will also cover the key...
