STM32h755 cores not running properly
Hello!I am working with the STM32h755 nucleo board. my project is cubemx generated.at first i created simple code that makes each core (m7,m4) to toggle a differenet LED.i see a differnce in the behavior when i am connected with a debugger and withou...
Resolved! Getting more current from GPIO
I'm using an STM32F373's UART to output MIDI data. Basiclly the TX USART pin needs to light an LED in the MIDI cable's opto-coupler. I currently have the TX pin connected directly to the MIDI DIN connector pin through a 200ohm resistor. I know thi...
USB HUB for M4 Controller
Hi we're using STM32L412RBT6P controller for our development process and NUCLEO-L412RB-P is the evaluation board we've chosen, and the selected controller has USB 2.0 full-speed crystal less solutionwith LPM and BCD and according to the requirement ...
STM32U5 I2C
STM32U5 + LSM6dslI want to read the general accelerometer register of the I2C interface.I think it can be achieved by using HAL_I2C_Mem_Read ().I set the second argument DevAddress to the value of the accelerometer slave address shifted left by 1 bi...
LPBAM: SRD indicates AHB3/APB3 is still active even after transfer is complete
Hi ST community,I'm developing an LPBAM use case using the B-U585AI-IOT02A dev board and it will be deployed in an IoT device empowered by an STM32U585 MCU.My application is:1. set up LPBAM such that: RTC wakeup will trigger an I2C3 master transmit a...
Resolved! unexpected register change TIM1->DIER / interrupt enable flag
Controller: STM32G431VBT6Compiler: arm-none-eabi-gcc version 12.2.1Libraries: CMSISI use STM32G431VBT6 for a sensorless BLDC motor control with zero-cross detection.TIM1 is used for PWM outputs. See below part of the code. RCC->APB2ENR |= RCC_APB2ENR...
Resolved! flash memory write problem
hello experts ,my device is stm32f103c8t6 ,cubeide 1.14.0it shows 64kb flash in ide but shows 128kb in stmcube programmer ,my issue is if i write flash from inside the programme while mcu running then it writes fine but when i erase the page and try ...
Resolved! STM32F030R8 PWM to LED (PA5)
Hi all, I am looking into generating a PWM signal using the Timers and route it to the PA5 pin to blink the LED, but PA5 does not have a TIM routed to it. I thought about just having a timer work in my code and toggle the pin every second by checking...
