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...
Hello, I am trying to set the device into standby mode before the actual code execution. I have set a pin as a wake-up source from standby mode and I need to run the actual code after waking up from standby mode. The workflow seems to work, for insta...
Hello there, We are designing the STM32U535 to operate in a low-power configuration. According to the datasheet, the current consumption in Run mode is 16.3 μA/MHz at 3.3 V, which is quite low. However, when measuring the actual device, even after su...
Hi,we are facing a strange problem. We are trying to boot up into USART1 bootloader by applying the correct pattern (BOOT0, BOOT1 pins).Then communicate with the system bootloader on USART1 (in this case 4800 Baud, even parity).There is just silence ...
Hi, when i try to build my current project i get: called object is not a function or function pointer in the stm32f103xb.h for whatever peripheral i use. For example stm32f103xb.h:657:29: error: called object is not a function or function pointer657...
I have an STM32H745 Discovery board. The first problem I encountered was when I was creating interfaces using TouchGFX. I could upload them to the microcontroller via the application without any issues, but when I uploaded the code file through C...
I'm new to microcontrollers. I bought a Nucleo-H755ZI-Q, I connect it to my PC, I make a simple program like turning on and off a LED but the card doesn't do it. I don't know if I have to make any adjustments because it's new.
Hi, I am integrating the STM32H7S7L8H6H in a custom board. In the reference manual I found two settings which I am looking for clarification for: 1) SBS_PMCR has a AXISRAM_WS bit to enable a single wait state for the AXISRAM. I do not have ECC enab...
I redid FatFS to work async or in polling mode. Works well on my STM32H755zi, on CM4. Most functions are enabled, though I didnt do all of them. Maybe plan on adding them later if there is any interest.Figured I'd share since not having an async FatF...
Hallo,I'm compiling with this option <-fpack-struct=1>Why, with this option, the instruction<WRITE_REG(hdma->Instance->CBR1, 0U);>generates hard fault? I don't understand, without changing nothing.thank you.
