Posted on April 13, 2013 at 17:39I have a potential divider circuit set up using the 3V and GND pins on the discovery board and two 100ohm pots, I measure a constant divided voltage of 1.25 (from ground to the ADC input) but when I debug in Uvision ...
Posted on April 15, 2013 at 19:55Hello Community, i´m having a stm32f3Discovery under the Keil´s µVision4 Compiler programming in c++. I got to the point, where i could use the ''NEW'' operator. To be honest, i have no idea, what is really goin...
Posted on April 18, 2013 at 09:21Hi, I am using an STM32L151VB part in a custom board. Is there any way to detect if an interrupt has been caused by a rising or a falling edge. I looked around in the reference manual and didnt find anything. I need ...
Posted on April 17, 2013 at 15:38 Hi everyone and thanks in advance for your help. I'm trying to configure an SPI link between my STM32F4VG407 and a Shift register (M74HC595). I wrote a simple code to start : //#include ''st...

Posted on April 16, 2013 at 15:15Does someone know where can i find a tutorial about configuring a FreeRTOS ARM Cortex-M4F demo application that targets an STMicroelectronics STM32F40XX microcontroller using eclipse please ? http://www.st.com/intern...
Posted on April 17, 2013 at 08:53Since yesterday, i can't establish a ST LINK connection with my STM32L1-Discovery board. I've tried it in CrossWorks on my MacBook, the error was 'ST-LINK LOG'. After that, I've tried it on my windows 7 pc with ST LI...
Posted on April 17, 2013 at 01:31Hi, currently I am trying to analyze the STM32F4Discovery schematic to get a minimal circuit using a STM32F407 oder STM32F405 in LQFP100. So I started an now ended up completely confused with a whole bunch of questio...
Posted on December 28, 2012 at 01:21 Hello All, I'm sending data over a bluetooth device to the stm32 discovery board on usart 2. Everything is great unless I send a large amount of data (80 bytes). If I send this large amount I only end up ...
Posted on April 15, 2013 at 15:14Hi Again ; In my application stm32f407 will enter stanfby mode then should wake up by 2 methods ; a rising edge on the PA0( wakeup _pin) and an alarm occurs everyday one time .. the first one I thing I will not get...
