mux writes: I’ve been doing some tests with the STM32F407 to see how fast it can go, STMicro has released an almost identical one that runs at 180MHz, is it a marketing thing ? will they release a 200MHz version in a few months? who cares, anyway, I was able to run the STM32F407 at […]
mux posted an update on his camera project OpenMV, an open-source tiny machine vision module using an STM32F4 ARM Cortex-M4 micro and an OV9650 sensor: USB Support- The camera now supports USB OTG full speed, I’ve also written a small userspace tool with libusb/SDL to interface with the camera and view the frame buffer, this makes it […]
mux writes: I wrote a tutorial before on how to setup a toolchain and build the STM32F4xx standard peripheral drivers into one convenient library, since then, a few people have asked me about the library, so to make life easier, I downloaded the latest StdPeriph/CMSIS, in addition to a few other libraries that I might […]
Frank Zhao posted his STM32F4 breakout board in the project log forum: I really like the STM32 family of ARM microcontrollers. This breakout board is a narrow design that fits perfectly on a breadboard. Every pin is accessible. It has USB, a reset button, and a bootload button. The chip itself has a permanent USB bootloader […]
mux blogged about his open source camera project: This a quick update on my camera project (OpenMV)… I’ve finally received the long overdue PCBs today and assembled one. I haven’t written any code yet, but I’ve managed to get it into DFU mode and upload a blinky, it seems to be working fine so far, no […]
Tinito informs us that a new STM32F4 discovery board has been announced, featuring a 2.4″ QVGA TFT LCD (apparently without touch sensor), 64Mbit of SDRAM, a Gyro and all pins available through pin headers. The data brief is available for download and the board lists for $24USD. Via the contact form.
TitanMKD posted an update to his STM32F4 based debug board we covered previously: This board is intended to be used as a portable multi-purpose debug/hack tool with very fast peripherals and MCU and use standard Dangerous Prototypes Sick Of Beige DP6037 case format A full open source firmware is planned using chibios and like Bus Pirate […]
TitanMKD is designing an STM32F4 based debug board using a DP6037 standard PCB size and a Sick of Beige case. The board features a Bus Pirate-like serial terminal interface. This board is intended to be used as a portable multi-purpose debug/hack tool with very fast peripherals and MCU and use standard Dangerous Prototypes Sick Of […]
alexwhittmore has posted a detailed tutorial highlighting an open source IDE and toolchain for the STM32F4 dev board on Max OSX Lion. He uses Indigo R Eclipse IDE for C/C++ Developers (Mac Cocoa 64-bit), Sourcery CodeBench Lite Edition, STM32F4 DSP and standard peripherals library and the STM32F4 Discovery board firmware package. Check out Alex’s website […]
Giovanni writes to inform us about his guide regarding the STM32F4-Discovery. This article will explain how to get started with the recently released STM32F4-Discovery board using ChibiOS/RT. This board is really cheap (below $20) and is an excellent evaluation platform for the STMicroelectronics Hi-Performance & DSP STM32F4 family. Via the contact form.
Nabil programed the STM32F4 DISCOVERY development board using the Bus Blaster JTAG debugger and open source OpenOCD software: My initial research lead me to texane’s github where he created a linux version of ST-LINK. It doesn’t support the STM32F4 yet, but there is a fork which is making good progress. I couldn’t get either to […]
