Posted on July 24, 2014 at 20:19HelloI must run ov7670 camera by stm32f4 discovery and send the image stream data to laptop via usb , So i need a source code or software for displaying this data .Thanks .
Posted on August 01, 2014 at 20:51Hi sir/madam when I am compiling my code for tcp/ip echoserver and echoclient I am getting the error error: storage size of 'echoServAddr' isn't known. I am compiling the code by using CooCox CoIDE To...
Posted on August 02, 2014 at 10:01Hi All, New to the STM32 so please bare with me.... I have setup timer4 to generate a sinewave modulated PWM using double buffered DMA and that works very well, I can see my waveform on the pin and it contains the c...
Posted on August 01, 2014 at 13:50Hello everybody I am trying to disable read out protection (level 1) on my stm32f407-discovery with flash loader demo (v2.6). I've connected Boot0 to Vdd, PB2 (boot1) to Gnd and my serial port (via max232) to usart1...
Posted on February 06, 2013 at 10:43Hello,I've a problem with my STM3240G-Eval board and my development tool chain. I use Atollic or Keil �Vision demo. When I want debug my program or ST examples, the development software send me ''Old ST-LINK firmw...

Posted on July 31, 2014 at 23:29Hi, I just received a new prototype with a STM32F215 processor and it is set up to use the SWD interface to initially flash the unit. on the ST-Link/v2 I have connected: pins 3,5 & 10 to gnd (3 & 5 to reduce noise) pi...
Posted on March 05, 2014 at 14:42Hi all,I have STM32F2 processor and I would like to receive all CAN messages with the valid frame and different IDs. Datasheet says a lot about configuring Identifier filtering, but nothing about how to configure it ...
Posted on August 01, 2014 at 16:04Hi,Can I interface directly max232 to STM32F205RBT6.I have given 5V to VCC of max232 & 3.3V to vcc of STM32.1. In datasheet of max232, it is given that Vih = 2V. So my 3.3V signal from STM32 will serve the purpose o...
