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 01, 2013 at 18:05I'm attempting to test out some basic programs on an STM32L151RD (Cortex-M3) using IAR's Embedded Workbench. I'm using an ST-LINK/V2 programmer. I've downloaded the Standard Peripherals Library and generally have been...
Posted on June 27, 2013 at 17:48I have recently run into a imprecise bus fault problem as indicated by my hard fault handler. I am using an Olimex STM-P103 development board (STM32F103RB CPU) and there is no OS or RTX present. I am pretty certain th...
Posted on March 13, 2013 at 11:57Hi, after I updated the STMStudio I'm not able to import all variables from the .efl file. After selecting a file there are not all variables shown. I tried different toolchains, but the problem is still there. I use...
Posted on July 01, 2013 at 06:48Dear All, I am new to this STM microcontroller. I started working on with some of the few examples provided in keil 4 .Presently i am working on STM32F217IG controller for which I wrote a small program...
