STM32 MCUs Products

I'm trying to measure IDD on a STM32 Nucleo-144 board and I am measuring high current of about 25ma in STOP2 from RTC. Even running the PWR_ModesSelection program it has high current. Am I supposed to be able to read micro amps thru JP5 ?

Can I call time(NULL) from my controller code to get the time?

I'm working with a Nucleo F429ZI. I have "time.h" included in my code, and whenever I call time(NULL), I get a "-1" returned, which I think means that the function call failed. Is there anyway to get the function time(NULL) to return the time, by con...

How to place some part of code in ITCM and DTCM in stm32h745 ?

Hi ,I am using stm32h745 and I am new to this dual core processor. I have some doubts with this processor access:1)Do both the processors mutually controllable i.e., can we start and stop cortex M4 using cortex M7 and vice versa .. ?2)I want to plac...

Which Nucleo board to be used for STM32F103RE & STM32F103VE microcontrollers?

I'm looking for evaluating some demo applications on STM32F103RE & STM32F103VE microcontrollers.Which NUCLEO board should I use for the purpose?I could find one NUCLEO-F103RB, but would it be compatible and/or the best choice for the microcontrollers...

SPI Dasi Chain: Is it possible to capture a 10-byte DMA array transmission with 10 1-byte transmission?

Hi there,I'm trying to create a Dasi Chain setup with STM32 Nucleo boards using the HAL library.My master should send a command to 10 slaves. It would be best to use DMA for the master to avoid blocking the mpu. HAL_SPI_Transmit_DMA(&hspi1, command_a...

Parallel SDRAM

Hello everyone, i would like to connect STM32F7 with multiple SDRAMs because i would like to get at least 256 MByte, i spent too much time trying to search for a detailed way, how to connect at first more thant one SDRAM together and then to connect ...

TIM1 pwm and TIM17 as systick source causes initialization bug

I configured a simple CubeMX project targeting the nucleo-f302r8, which I am using as a development board.My project uses TIM1 CH1N (PB13) as a PWM output and TIM17 as the systick source. I chose TIM17 arbitrarily as I don't anticipate using it in th...
