Battery affecting program execution for stepper motor driver on nucleo board

Using a Nucleo f401re nucleo board with a 'X-NUCLEO-IHM03A1' shield that houses a powerSTEP01 stepper motor driver. I've downloaded and run the example projects from 'X-CUBE-SPN3' by ST and the stepper motor runs perfectly. I then generated my own pr...

Hi, please where can I find any example how to open/write/read a file in the flash for the stm32l4?

Automatic Serial numbering to differentiate the various devices

Hello to everyone,I am developing an indoor sensor system using a ST microcontroller. The hardware used includes a battery power supply, an analog sensor and a radio transmission part. Assuming that I produce more pieces of the sensor, I would like t...

TIMx Link TIMX to Measure External Frequency

Am using NUCLEO-STM32H723 Nucleo-144 board.Sorry, but I have no experience with the above MCU/TIMx.My goal is to measure external frequency as accurately as possible.I'm interested to know how to Link between two timers.Example : TIM3 ( Master ) TI...

I need to configure CAN filters in such a way that only ID 0x80 and IDs between 0x200 and 0x300 passes all others are not allowed to be passed. How to do that?

I tried in this way but the problem is only 200-300 can pass but 80h is not passed. if i use if else then only 80h is passed not 200-300h. So, the problem is i can pass either 80h or 200h-300h. Not both 80h and 200-300h. #define Filter_ID1  0x80#def...

Why Microcontroller is halted after Power-on Reset?

Hi,I wrote a simple Led blinking program in STM32F303CB.-> On power-on reset Controller is not getting started.-> I used Internal Clock and External Clock-> But the same behavior in both the cases.Thanks.

STM32L552ZE-Q SAI I2S slave pass data to master output

My development board is STM32L552ZE-Q.I want to use SAI slave mode receive i2s signal and SAI master transmit i2s signal.I can observe clock and makesure data in have input.But my data out isn't similar with my input.Does any one can help me, thanks

SPI TXEIE is not SET even after configured it

I have done some debugging on SPI interrupt problem. So, I have a function that SPI_SendDataIT which means SPI send data with interrupt. the interrupt will be triggered if TXE flag is SET. But we have to enable the TXEIE first. But, what happen is, a...

What is the difference between STM32F100RBT6 and STM32F100RBTB? What is the meaning of the ending 'B'? Someone told me that the STM32F100RBT6 is obsolete. Are there any problems to be expected by exchanging the devices? Best regards Peter
