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...
Hello, normally I use STM32F103 microcontrollers and recently got a STM32H747 Discovery Kit. However I have no idea how to develop a program for it or compile that program. Normally I use Atollic True Studio but I don't know if it supports this disco...
HI ?i work with STM32F103CB ,The problem is the STM does not toggle the RTS. RTS still tied high i can't find the problem can someone help me please.we found here my code.void USART_GPIO_Init(void){ // Configuration of GPIOA clock source RCC_APB2Pe...
