MicroPython v1.24 release adds support for RP2350 and ESP32-C6 microcontrollers, various RISC-V improvements

Micropython v1.24 with ESP32-C6 and RP2350 support

MicroPython has become one of the most popular ways of programming microcontrollers, and the just-released MicroPython v1.24 adds support for the widely-used Raspberry Pi RP2350 and Espresif ESP32-C6 microcontrollers and a range of other changes. Those include improved RISC-V support with native code generation, an updated Zephyr v3.7.0 RTOS with threading support, unified TinyUSB bindings across ports, a portable UART IRQ API, and enhanced mpremote recursive copy. Damien George goes into more detail about the RISC-V improvements: … include an RV32IMC native code emitter, native NLR and GC register scanning implementations for 32- and 64-bit RISC-V, support for placing RV32IMC native code in .mpy files and also freezing it, and RISC-V semihosting support. Testing for RISC-V is done with the qemu and unix ports, and the support is utilised in the esp32 and rp2 ports. The Raspberry Pi RP2350 comes with both Arm Cortex-M33 and RISC-V cores, and the good […]

ESP32-C6 WiFi 6 and Bluetooth 5.0 USB-C development board integrates 1.47-inch TFT LCD Display

ESP32-C6-LCD-1.47

Waveshare has introduced the ESP32-C6-LCD-1.47 development board powered by an ESP32-C6 RISC-V microcontroller with WiFi 6 and Bluetooth 5 connectivity and equipped with a 1.47-inch display with a 172×320 resolution. With a 4MB flash, an RGB LED, and a microSD card slot for extra storage, this board is suitable for projects that need a compact display, low power consumption, and wireless connectivity such as AIoT applications and human-machine interfaces (HMI). Earlier this month, we covered the ESP32-S3 USB dongle, another development board from Waveshare designed for HMI applications with the same 1.47-inch display with a 172×320 resolution, but a USB Type-A port instead of the USB-C port found in the model covered today. In the past, we’ve written about other ESP32-based development boards for HMI applications, including the LILYGO T-HMI, ESP32-S3-Touch-LCD-4.3B, and Waveshare’s ESP32-S3 LCD Driver Board supporting both square and round displays.

Linux 6.11 Release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.11 release

Linux 6.11 is out with Linus Torvalds’ announcement on the Linux kernel mailing list (LKML): I’m once again on the road and not in my normal timezone, but it’s Sunday afternoon here in Vienna, and 6.11 is out. The last week was actually pretty quiet and calm, which is nice to see. The shortlog is below for anybody who wants to look at the details, but it really isn’t very many patches, and the patches are all pretty small. Nothing in particular stands out – the biggest patch in here is for Hyper-V Confidential Computing documentation. Anyway, with this, the merge window will obviously open tomorrow, and I already have 40+ pull requests pending. That said, exactly _because_ I’m on the road, it will probably be a fairly slow start to the merge window, since not only am I on my laptop, there’s OSS Europe starting tomorrow and then the […]
