STEPPER MOTOR using I2C

Hi, I have a problem with starting a stepper motor using the I2C bus. It uses the NUCLEO-F746ZG microprocessor, the SMC 64-BP stepper motor driver and the KH1634-03CA stepper motor. The main problem is finding the address of the controller and giving...

How to reduce the consumption of the Nucleo-L073RZ board to less than 700uA? How to disable J-Link part on the board?

I am developing a card with a supercap storage, I designed it for a consumption of 40uA as it is written in the datasheet, however I reach only 3mA and I use the "standby" mode written and found on the internet. Can you explain me how to disable the ...

FMC behaviour if read before a previous write cycle has completed

I connecting an FPGA slave to an STM32F7 FMC 'sram' bus. For this particular project, I need to access the bus both inside and outside of an interrupt. Because there is a write FIFO, can I assume that writes are atomic and don't require mutual exclus...

How should I study STM32 MCU

Hello,I am a mechanical engineer that is studying Mechatronics as master degree. I am getting keen on embedded system after I have taken a course on operating systems on embedded systems. I have never used STM32 word and I have just received a stm32f...

ADC with external trigger source via a timer. STM32G431 with NUCLEO G431RB

Hello guys, I'm new to the ST controllers. My question would be how can I initialize an ADC that is waiting for an external signal from a timer. I have initialized a timer interrupt that is triggered every 1 ms at 170 Mhz clock frequency. The timer a...

ST community Hello, my question is I want to use two generic interrupts on STM32F302R8T6 but one of them is not working. TIM6->DIER |= (1<<0); TIM2_IRQHandler works when I comment out this part. How to use global truncation for both?
