Posted on January 31, 2013 at 14:11Hi I am a power electronics engineer and I have been using the STM32F4 to develop AC motor drives and its great I am now working on an application with space vector modulation and I have ran into a difficulty which...
Posted on February 07, 2013 at 01:53Hi,excuse me for my bad english,I'm new in the microcontrollers field, so I've some uncertainty on the use of the dma to read and write from USART. At the moment I'm interfacing the stm32f100B with a medical modul...
Posted on February 09, 2013 at 16:40Hi, I work with STM32F0. I want use Output compare (PA2) TIM2_CH3 for manchester encoder. I like use DMA for this. The F0 have a DMA for Output Compare ?
Posted on August 24, 2012 at 16:23hi i have a problem with the stm32w mb851a i would generate a random number. i have try to use the function rand() and I include header filebut when i execute the program it jump at void __attribute__ ((weak)) Defa...
Posted on February 08, 2013 at 17:34 Hi, I have a quick quiestion: my toolchain complains that instruction strexb r2, r2, [r3] is illegal (registers may not be the same), while strex r2, r2, [r0] is fine. The qu...
Posted on February 06, 2013 at 15:43Im using a quadrature encoder hooked up to TIM3-CH1/2 and it works fine, counting both edges, up and down. First question is how to read the TIM3-counter values from within a regular (50 us) ISR. Using TIM_GetCoun...

Posted on February 06, 2013 at 13:31 hello, i'm trying to connect my stm32f0 discovery with the pc and set up a uart connection. I have found the following code (in this community) but i can't get it to work. Does anyone have a suggestion...
Posted on February 04, 2013 at 04:05It appears the TIM4 OC interrupts on CH2 results in occasionally missing an Update (overflow) interrupt. The situation is a 1 PPS GPS pulse triggers the TIM4 CH1 input capture. The 16 bit counter time is extend...
Posted on February 08, 2013 at 10:08Hi all, I'm still new in the ST environment, I'm trying to get a generic wireless m-bus example going with the STM32l152VBT6 board. For the moment it is still unsuccessful . When I debug my main program, I can see...
