Posted on June 09, 2015 at 05:04Hi everyone,I have a STM32F072B Nucleo board (god knows why, should have listen to good advises -.-) and IAR Workbench with the 32Kb code limit version. V7.40.In an attempt to get more familiar with IAR tools I was lo...
Posted on June 09, 2015 at 19:26I can load the Windows USB driver (into a VM--I don't oen any actual Windows box), and plug in a discovery board and all is well. Can update firmware, load stuff, etc. But when I try to connect another apparently iden...

Posted on June 09, 2015 at 17:24Hello, I would like to clock RTC with external clocking signal. The problem is, I have 10MHz TTL 0-5V signal at disposal but pins OSC_IN and OSC_OUT have TC pin structure (standart 3.3V I/O). I cannot simply reduce vo...
Posted on February 11, 2014 at 18:18 Hello, Today, we are using a STM32F405VG which is connected through I2S to a PCM interface of a Bluetooth Controller. The STM32F405VG and the Bluetooth Controller exchange audio data through this I2S with audio f...
Posted on June 05, 2015 at 21:16I am a Stm32 new learner.Recently I have had two Stm32 chips to communicated with eachother by using it wardware SPI.After I wrote the master and slave program and downloaded it into both stm32 chips.I used a logic an...
Posted on June 09, 2015 at 13:46Hello,is it possible to generate a interrupt when the pin NRST is activated??I need to reset some variable before the reset of the microcontroller.Thank's!!! #stm32f4-reset-pin
Posted on May 29, 2015 at 12:46I am novice to ST family. I have added DMA1_Stream5 Handler in keil example. When I put breakpoint over there ,it is not executing . Here is my code . int main(void) { GPIO_InitTypeDef GPIO_InitStructu...
Posted on June 09, 2015 at 10:29I discovered this by chance, copying user_functions from an F100 project to the new F030 project. My delay function is based on TIM2 and it works normally on the F030. Is the TIM2 on the F030 or does the compiler chan...
