The Wi-R protocol is a non-radiative near-field communication technology that uses Electro-Quasistatic (EQS) fields for communication enabling the body to be used as a conductor and that consumes up to 100x less energy per bit compared to Bluetooth. In a sense, Wi-R combines wireless and wired communication. Wi-R itself only has a wireless range of 5 to 10cm, but since it also uses the body to which the Wi-R device is attached, the range on the conductor is up to 5 meters. While traditional wireless solutions like Bluetooth create a 5 to 10-meter field around a person, the Wi-R protocol creates a body area network (BAN) that could be used to connect a smartphone to a pacemaker, smartwatch, and/or headphones with higher security/privacy and longer battery life. One of the first Wi-R chips is Ixana YR11 with up to 1Mbps data rate, and they are working on a YR21 [...] The post The Wi-R protocol relies on body for data communication, consumes up to 100x less than Bluetooth appeared first on CNX Software - Embedded Systems News.

ESP32 MPY-Jama is a cross-platform MicroPython IDE specifically designed for ESP32 boards with a file manager, a REPL terminal, real-time dashboards, and various ESP32-specific features. The IDE is an open-source Python program using pyWebView and pySerial plus some JavaScript for the user interface, and the developer of the program, Jean-Christophe Bos, provides binaries for Windows 64-bit and macOS 64-bit Arm or x86. It’s also possible to use it in Linux but needs to be built from source. Some of the key features of the ESP32 MPY-Jama IDE include: MicroPython code editor with syntax highlighting REPL interface Access to information dashboards with real-time data about WiFi and Bluetooth connections, system info with GPIO status, CPU frequency, memory and SPI flash details Easy 2-click methods to connect to WiFi and create an access point Graphical interface to install a new firmware through esptool Ability to create, import, and run “Jama Funcs” mini-applications [...] The post ESP32 MPY-Jama is a MicroPython IDE for ESP32 boards appeared first on CNX Software - Embedded Systems News.

I encountered some python path issues when using legacy kernel with edge release. Rock5b Legacy Kernel v5.10 & Ubuntu Kinetic. Debian Bullseye & Ubuntu Kinetic Don't have a /usr/bin/python symlink that points to python2, due to deprecation of Python 2 This breaks some old python scripts etc in linux-headers deb There is also a python-is-python3 that creates a /usr/bin/python symlink pointing to python3 So better to patch the legacy kernel incase cause issues later on. The patchfile is based off radxa kernel linux-5.10-gen-rkr3.4 Note: Any legacy kernel build (version 5.10 and previous) will be effected on a edge release. Sorry if not implemented in correct place or patchfile name, first time using armbian build system & bash scripting etc Thanks View the full article

I have started this months ago, but due to high demand from other subjects (armbian-next) haven't had time to finish. What I did here was take Khadas tree (.66) and rebase it on top of rk3.4/Radxa tree (.110) for the rock-5b, similar to what was done for the OrangePi5. Some patches conflicted and I intervened (those are marked as intervention). This needs review, a board file, a developer with the new Khadas I/O board for UART, and some luck, patience to fix my mistakes, and might just work. Who knows? If it's useless just bin this... There's two patch files, one with stuff I deemed "required" and other with stuff "might be nice". The MCU stuff of Khadas is heavily entwined in there... The complete git tree with those patches is at summary: https://rpardini.github.io/linux/armbian_rockchip_rk3588_legacy_with_initial_kedge2_20230203.html git tree: https://github.com/rpardini/linux/tree/armbian_rockchip_rk3588_legacy_with_initial_kedge2_20230203 Pinging @150balbes who @igorpecovnik told me might be working the kedge2...
