Posted on March 03, 2016 at 14:48Hi there, is it possible to divide the EXTI4_15_IRQHandler into smaller groups of EXTI Lines ? For example EXTI0_1_IRQHandler is responsible for EXTI line 0 and 1 and EXTI2_3_IRQHandler for EXTI line 2 and 3. But all...
Posted on March 02, 2016 at 09:38Hi, I am using X-NUCLEO-CCA02M1 (mems mics) with nucleo stm32f4.I want to record audio by the mics ans store it the internal flash.Didn`t find any materials\examples for storing to flash .I found Audio_playback_and_...
Posted on March 03, 2016 at 17:09 Hello everyone, I am using the RTC on a stm32l151VC. I am using sleep modes in order so save battery life. As I need to tell the OS how long I have been sleeping (Systick is turned off) I save the time t...
Posted on March 02, 2016 at 14:00 Hello everyone, I'm trying to initialize the DMA for SPI2 but DMA is not working for my code , I don't know the reason. Surely I can say that it's not working as the LED which is turned ON in ISR is not glowing....
Posted on March 02, 2016 at 15:37My particularquestionis I need a processor that can quickly measure the analog voltage i.e., it has the fastest ADC or preferably more, which may be combined in one. I find STM32F303 with 4x 5MSPS ADC, but perhaps e...
Posted on March 03, 2016 at 15:36 Hello ST-community, I am able to setup my external SRAM and access and test (memtest) its memory regions. It works! However, I do not know if my configurations are correct. It is hard for me to und...
Posted on February 25, 2016 at 16:07Hi, I'm quite confused about 5V-tolerant input pins of STM32F405. Referring to the manual, the picture ''Basic structure of a five-volt tolerant I/O port bit'' shows diodes that protect the port. In this configura...
Posted on March 03, 2016 at 10:14Hello, I have been designing a controller for an interleaved power converter using the STM32F746 Discovery board. Since I need to have four pulses with different duty cycles and phase delays (which will be variable),...
Posted on March 01, 2016 at 12:11Hi all,Trying to implement a basic external interruption on the stm32f407 discovery board, the microcontroller allways freeze after receiving external interrupt. After some test i discover interrupt cause a call to t...
Posted on March 02, 2016 at 18:12Folks, The 64 pin package of the STM32F103 has no Vref pins. I can't see any way, though, of switching between external and internal ref for *any* of the parts. I'm assuming that where there is no Vref pin, you can ...
