Posted on April 01, 2012 at 23:12in my project, i must generate a sinusoidal wave and i have to receive this wave by ADC. this signal is a response harmonic of a filter. so i want to calculate the gain and the phase shift but i don't know how. can i...

Posted on April 10, 2012 at 18:40Can someone from STM confirm what the most recent version of this file is please ?
Posted on March 29, 2012 at 21:49Hi all, i'm sorry if this has been discuss before, but from reading posts i'm still some what unclear, thus my post.Right here goes :)Has anyone implemented reliably SDIO using DMA along with say FatFS file system ? ...

Posted on April 09, 2012 at 18:46 Is there a proper way to go into low-power sleep? When I try to step through in the debugger (or at least, let the program run and then pause it), the LPSDSR flag never gets set. And when I let the program run wit...
Posted on April 05, 2012 at 18:43My application calls for using an external oscillator (not a crystal) as a clock source. To test this, I have an arbitrary function generator outputting a 50% duty cycle square wave of the expected clock rate. The MC...
Posted on February 12, 2012 at 01:30Hi, I have modified an example project of IAR for STM32L1XX with a new library definition (one file .c and one file .h). In the file .h I have defined a variable that I use in the .c file. The function defined in ...
Posted on April 08, 2012 at 16:18Hello ! I I start working with STM32L151 + Keil + ULINK2 , and met a problem : after some code, likely it was scommand GPIOA->BSRRL=GPIO_BSRR_BS_2;processor stop the debugging, and a can not start a new debu...
Posted on April 03, 2012 at 20:12Hello at all, I have to mesaure the delay between 2 signals that I have in input to the microcontroller. I saw the example of the PWM input. I supposed to use an OR gate to have both front to the same pin but I think...
