STM32 MCUs Products

If we initialize an array would it be stored in a different partition of RAM in comparison with the condition under which we do not initialize the array ? initialized array: float Data_Set_X[15000]={0}; uninitialized: float Data_Set_X[15000];

the problem is that When I define the arrays like this :float Data_Set_X[15000]; float Data_Set_Y[15000]; float Data_Set_Z[15000];I get the RAM overflow error which is: `.bss' will not fit in region `RAM' Timer-Blink-Test_CM7 C/C++ Problemwhen I init...

Resolved! Problem using HAL_UART_Transmit_IT

I'm using the HAL_UART_Transmit_IT procedure on a STM32G431 for the LPUART on a 115200 baud communication to a Putty terminal. The MCU is also running ST Motor code.I have some simple 3 character commands that either set variables in the code or read...

Dear ST; RTC for STM32G0 is not working ( Timestamp Mode ). Could you please check this problem.Best regards.

SysTick, why not part of CMSIS? (NUCLEO-G070RB)

So I have a NUCLEO-G070RB board here and I am not using the HAL library, but just CMSIS libraries.I see the SysTick functions are part of the HAL not CMSIS. is there a particular reason? I would figure since it's part of the M0+ core it would be i...

Resolved! I can't make timer stop while debuging

Posted on January 09, 2017 at 18:29 Hello. I have a problem trying to stop a timer in debug mode. I am using a NUCLEO-F072RB. I use timer 7, one of the basic timers, to generate an interrupt. In order to be able to stop the timer in debu...

H72X: Do OCTOSPI work as slave device in SPI, Dual-SPI or QuadSPI mode?

I'm researching various ways to generate serial bit streams clocked by an external source.I'm wondering if OCTOSPI device working in simpler modes (e.g., SPI, Dual-SPI and QuadSPI) can do this.Any info is appreciated.Thanks in advance.

Resolved! STM32F4 DMA messing with my PWM, what am I missing?

Hello,I am having a problem with my STM32F369l-DISCO board, as the title says it has to do with the DMA and PWM output.So I need a 800kHz PWM signal for some SK6812 LEDs, I already did achieve this with an STM32L433CCT on a custom board using this gu...
