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...
Hi,I'm trying to use the QSPI peripheral on the STM32F746, specifically on the STM32F746 Discovery board, however, as soon as any QSPI interrupt is enabled there is an interrupt present but upon reading the status registers there is no visible interr...
Hello!I'm experiencing difficulties using STM32-MAT-TARGET to generate code for STM32 controllers from Simulink models using the provided blocks for USART communication.STM32-MAT-TARGET : 4.4.2Matlab 2017bMDK-ARM Professional Version : 5.14MCU : STM3...
Hi, I designed my first own board with a STM32F030F4P6 on it. Additionally a got me a ST-Link V2 for programing and debugging. As IDEIuse CubeMXIDE. I already successfully programed some Nucleos with it. With my own board I don't get a connection to ...
HI!I am currently trying to minimise the standby consumption of a STM32H7 down to theabsolute minimum. Only the change of one Pin (PA0) is selected as wakeup event. No need for backup ram, Pin drivers, RTC nor anything else. The MCU shall only switch...
I want to periodically check the state of the RAM ECC detection in my firmware on a STM32H753.The ECC mechanism is well described in the Reference Manual for the Flash but not very well (in my opinion) for the RAM.I've seen that there are dedicated i...
If I understand correctly, on STM32H7, a double error in Flash triggers a BusFault. is it possible to disable the generation of this exception ?
Hi,after encountering the problem with my non-CMSIS-based project, I tried to just set up a simple project in CubeMX, just activating the USART2 and selecting HSI16 as clk-source for the USART.Starting the debugger shows, as already seen in my origin...
Hello everyone, I have a question related to MCU oscillator. Honestly, i usually design MCU with external crystal , by belief that it is surely always better internal oscillator. Even i believed that if MCU isn't run with external crystal will make s...
Hello,I'm using the STM32L4A6RG and I'm interested in the exact behavior / rating of a GPIO-pin when configured as pull-up. The datasheet says, that if configured as pull-up, the maximum voltage allowed on that pin is Vdd + 0.3 V. That means there is...
I'm playing with the L1-cache of STM32H753. What I am trying to do is to provoke -on purpose- an inconsistency between the cache and the RAM as follows: set up the SRAM region as write-through cacheableenable the data cachewrite something to a variab...
