STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on March 03, 2016 at 09:22Hi all,Thanks in advance for your time spent on this topic.I have spent several months on STM32 project, fine with software coding, but keep confusion on the startup file, which would appear inalmost every project as...
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 02, 2016 at 12:11Hello, I'm using the internal EEPROM on a brand new STM32L021. In order to save some data into that EEPROM in an ''asynchronous'' way, I use DMA1 channel 1 in MEM2MEM configuration. My issue is that as soon as DMA_CC...
