Posted on April 11, 2012 at 02:22I seem to run into a lot of issues! I'm trying to get my STM32L Discovery board to wake up from low-power sleep with the Flash turned off. I'm using the User button (tied to PA0) to wake it up as an external interrup...
Posted on April 10, 2012 at 17:50Hi,I am a university undergrad and I am designing a Digital storage oscilloscope. I need the micro controller's DAC output for DC voltage. I have seen the sample code and I know how to setup the timer, link the DMA t...
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 12:18hi i'm wondering how can i program the stmf4discovery using the usart??
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...
