Adafruit’s PioMatter library adds HUB75 RGB LED Matrix support to the Raspberry Pi 5

The Raspberry Pi 5 brought a more powerful CPU and GPU and faster I/Os compared to the Raspberry Pi 4, as well as some incompatibilities. While the transition from a Raspberry Pi 4 to a Raspberry Pi 5 is usually painless for most applications, Adafruit notes that the ability to drive HUB75 RGB LED matrices was lost on the Raspberry Pi 5 which now relies on the Raspberry Pi RP1 peripheral control to drive GPIOs instead of the Broadcom processor directly controlling them. The company has now addressed that by using the PIO (Programmable I/O) block in the RP1 chip, yes that’s the same PIOs as found in the RP2040 or RP2350 microcontroller, to drive HUB75 RGB LED matrices from the Raspberry Pi 5, and their work can be found on the Adafruit-Blinka-Raspberry-Pi5-Piomatter repository on GitHub. The instructions to install the Adafruit Blinka Raspberry Pi 5 PioMatter library (or just […]

FlashMyPico – Raspberry Pi Pico / Pico 2 code editing and firmware flashing from a web browser

FlashMyPico website allows you to write C code, build the firmware, and flash it to your Raspberry Pi Pico, Pico W, Pico 2, or Pico 2 W directly from a web browser instead of having to check out the code from GitHub, build it in a terminal, and then manually copy the resulting binary. I’ve given it a quick with a Raspberry Pi Pico 2 board. The first step is to head over to flashmypico.com from your computer or even an Android smartphone. You’ll need a web browser that supports WebUSB, so for example, Firefox is not an option, and I eventually had to use Google Chrome instead. There’s a detect device link on the bottom left, so I clicked on that first, and my Raspberry Pi Pico 2 was detected as “RP2350 Boot” after I put it in bootloader mode. But it just told me that my board is […]

CPico RP2350 is another Raspberry Pi Pico 2 alternative with USB-C, 8MB flash, 2MB PSRAM, BConnect I2C & debug ports

iLabs CPico RP2350 is a Raspberry Pi Pico 2 alternative with the same form factor, still based on the Raspberry Pi RP2350 microcontroller but equipped with a USB-C port, 8MB flash, 2MB PSRAM, a Reset button, and Bconnect I2C and debug ports. Apart from that, the CPico RP2350 retains the other features of the Raspberry Pi Pico 2 including the two 20-pin PGIO headers, and BOOT button. It joins other Raspberry Pi Pico 2 alternatives like the Waveshare RP2350-Plus adding battery support. CPico RP2350 specifications: SoC – Raspberry Pi RP2350 CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone, Secure boot Dual-core RISC-V Hazard3 @ 150 MHz Up two cores can be used at any given time Memory – 520 KB on-chip SRAM Security 8KB of anti-fuse OTP for key storage Secure boot (Arm only) SHA-256 acceleration Hardware TRNG Fast glitch detectors Package – QFN-60 Memory – 2 MP […]

FOSSASIA 2025 – Operating systems, open hardware, and firmware sessions

The FOSSASIA Summit is the closest we have to FOSDEM in Asia. It’s a free and open-source event taking place each year in Asia, and FOSSASIA 2025 will take place in Bangkok, Thailand on March 13-15 this year. It won’t have quite as many speakers and sessions as in FOSDEM 2025 (968 speakers, 930 events), but the 3-day event will still have over 170 speakers and more than 200 sessions. Most of the sessions are for high-level software with topics like AI and data science, databases, cloud, and web3, but I also noticed a few sessions related to “Hardware and firmware” and “Operating System” which are closer to what we cover here at CNX Software. So I’ll make a virtual schedule based on those two tracks to check out any potentially interesting talks. None of those sessions take place on March 13, so we’ll only have a schedule for March […]
