STM32 MCUs Products

I am trying to Debug and Run LED Blinking code with out IDE. I Debug and Run code with IDE it was working.Can any one suggest how can i do this through command line? I use STM32 -NUCLEO-H745ZI-Q board

How do you specify GPIO ports and pins as function inputs?

I am new to STM32s programing in general and am trying to create some simple libraries, altough I have no idea how I would make it so that I can write it in a way, that needed ports and pins are given in function inputs. For example: int HCSR04_Dista...

Processing time with STM32H7A3 differs depending on the variable.

Hello.I am developing with a STM32H7A3.When dealing with local variables or global variables when executing test code on the microcomputer, the processing time when using global variables is about twice as long as when using local variables.Is this p...

CAN protocol forwarding limits?

Hi, I would like to forward about 2048 bytes via CAN protocol.I am using an STML4 and have implemented a solution in which sending an STM transmits in the following way:void CAN1_Tx(){ CAN_TxHeaderTypeDef TxHeader; uint32_t TxMailbox; uint8_t message...

Multiple I2C DMA requests on STM32H7, chained together

Hi, I want to transmit the following sequence with DMA, ideally without any interrupt (except once all the data transferred i.e. at the end of the whole operation).I'm talking in I2C with a device that works like that :Send one byte for read request ...

GPIO output voltage level in stm32g4

I want to know the ouput level of the pin PA3 wich has a structure as TT_a (3.6 V tolerant I/O)the table provided in the datasheet is a bit tricky to understand. Which are the row that I should consider for the PA3 pin? Cmos or TTL or the others?

Hi. I am very new for ST mcus.. Here, I am trying to set set timer2 for interrupt. Assigned PE2 for toggle, In STM32Cube IDE, set clock, enabled tim2 global interrupt. but I am not getting timer interrupt under void HAL_TI();
