STMicro STM32F4 (Cortex M4) vs STM32F7 (Cortex M7) Graphics Demo

STMicro announced their latest STM32F7 micro-controller family based on ARM Cortex M7 last week. As ARM Techcon 2014 is now taking place, the company has uploaded an infomercial on their YouTube account, where STMicro and ARM representatives are interviewed about the new family, and talk about its performance, power consumption, target applications, business prospects, and so on. But there’s also an a short demo with two development kits one with a STM32F4 cortex M4 micro-controller, and the other with a STM32F7 micro-controllers. Since both MCU families are pin-to-pin compatible, the hardware is identical except for the MCU. Both kits are pre-loaded with a 3D graphics demo (ray tracer), and the board with STM32F7 completes the demo in about half the time of the one with STM32F439, allegedly with about the same power consumption (7 coremarks / mW). The video is about 8 minutes long, and the demo starts at 1:25. […]

HydraBus is an Open Source Hardware STM32 Devkit with Support for NFC via HydraNFC Shield

Recently, I wrote about the public availability of a MicroPython board based on STMicro STM32F4 Cortex M4 support that can easily be programmed with Python. It turns out there’s another STM32 board called HydraBus, also supporting Micro Python firmware, or another embedded firmware based on ChibiOS, together with an optional HydraNFC shield capable of sniffing, reading/writing or emulating any 13.56MHz NFC tags. HydraBus Specifications: MCU – STMicro TM32F405RG micro-controller @ 168 MHz with 1MB flash, 192KB SRAM, and an FPU. External Storage – Micro SD card slot up to 48MHz (~24MB/s) Expansion Headers – 4 headers with access to 44 I/Os (some already used by micro SD and USB 1 & 2). USB – 2x micro USB connector including 1x OTG port, and 1x device/host port, both with ESD protection. Misc – Reset and user button, user LED, Power – 5V via micro USB port. Dimensions – 60mm x […]

$18 Matchstick is an HDMI TV Stick Running Firefox OS (Crowdfunding)

A few month ago, a Firefox OS HDMI streaming stick (codenamed netcast) by Mozilla that would compete with Google Chromecast was previewed. It is now called Matchstick, based on Rockchip RK3066 and has just been launched on Kickstarter. MatchStick technical specifications: SoC – Rockchip RK3066 dual core Cortex A9 processor @ 1.2 GHz with Mali-400 MP4 GPU System Memory – 1GB DDR3 (micron) Storage – 4 GB flash.

Finally… An Android TV Stick with an Ethernet Port

Ever since MK802 hit the market in April 2012, I’ve been expecting HDMI TV Sticks with Ethernet ports, but it never really materialized. There have been many small TV boxes, but AFAIK none of which could simply be insert in the back of your TV. Thanks to MK802 V we now have an HDMI TV dongle, powered by Rockchip RK3288 quad core Cortex A12/A17 processor, featuring an Ethernet port. MK802 V specifications: SoC – Rockchip 3288 quad core ARM Cortex A12/A17 up to 1.8 GHz with Mali-T764 GPU System Memory – 2 GB DDR3 Storage – 8 GB NAND flash (16GB optional) + micro SD slot (up to 32GB) Video / Audio Output – HDMI 2.0 (male) Video Codecs – MPEG-1, MPEG-2, MPEG-4, H.263, H.264, H.265, AVS, VC-1, RV, VP6/VP8, MVC (1080p) Sorenson Spark, MVC up to 4K2K @ 60fps Audio Formats – MP1, MP2, MP3, WMA, WAV, OGG, OGA, […]
