Posted on November 30, 2014 at 23:45I'm currently working on a university project that involves the analogue to digital converter on the STM32F0 discovery board. I've studied the manual and (as far as I can tell), initialized the registers correctly...
Posted on December 01, 2014 at 00:00It seems like the STM32CubeL1 template linker and startup script (for GCC) defines too many interrupt vectors. The STM32L1 reference manual states that the last used vector for all categories of STM32L1 chips is a...
Posted on November 14, 2014 at 23:30Hello, I wish to determine the mean time between failures of the NAND onboard the STM32F327 onboard our design. I've looked in the three large pdfs of its documentation for things like 'write cycle' and 'failure' ...
Posted on December 01, 2014 at 09:48Hello all,my application is based on stm32l152, I use StdPeriph_Driver and STM32_USB-FS-Device_Driver.USB transfer works fine until I disconnect usb cable. After disconnecting the firmware stuck running just inter...
Posted on November 24, 2014 at 10:56Hi, My application wakes-up from Stop Mode every 100mSec, takes ADC conversion from two channels in Scan mode to DMA then makes some processing. I get roughly +1.5% error. When i disable the Stop Mode but sampl...
Posted on November 26, 2014 at 16:17Hello!I am ussing STM32CubeF4 to implement a USB Host application on a STM32F4 -discovery board. When I connect a USB stick it never is detected. Connect interrupt must be raised but that is not happening. Any ide...
