Posted on July 03, 2013 at 06:21Hello, I'm on stm32f3.As far as I know, comparators on the device is very fast so it's very suitable to detect short circuit and over current condition in 50 ns. but most of shunt resistor has very LOW value. so it sh...
Posted on May 28, 2013 at 22:42 Take a look at the video below, which shows Linux, in its uClinuxform, running on the STM32F437 microcontoller: http://www.youtube.com/watch?v=_uO8KfhfY2Y&feature=youtu.be The novelty of this con...
Posted on July 02, 2013 at 20:57In a project I have a periodic interrupt (5ms) that misses a beat from time to time (1-2min).I have an os that will globally disable interrupts (set primask to 1) for very short time then re-enable them. I suspect it ...
Posted on February 24, 2013 at 02:29Hello everyone. As many may have noticed, the STM32F4 discovery boards comes with an unfitted OSC32 crystal (X3) & biasing caps (C16 & C27). Did anyone ever tried to provide her/his the board with those missing c...
Posted on July 02, 2013 at 10:46 Hi, I connected the ethernet port of the STM32F10C-Eval to my pc using an ethernet cable. But the led of the ethernet port is not blinking which means that the connection is not detected. I have changed the cable but...
Posted on July 01, 2013 at 15:36 Writing in 'C', I use __disable_irq(void) before reading a value that gets updated in an interrupt service routine. __disable_irq(); //prevent serial interrupts Count = TSp->DataAvailable; //get number...

Posted on July 02, 2013 at 14:58Hi,I'm working with stm3220G eval board. I need a simple example, where I can communicate pc-usb(otg), and so I can send a byte to board and vice versa. I installed virtualcom, I try with all device examples, but I ha...
