STM32F769I-Discovery CAN BUS
I work with STM32F769I-discovery board. in CubeMX CAN bus interface are not available to be selected. Can someone point me to the right diretion of initialising CANBUS?Many thanks!

Why low voltage on VBAT hold the read command on UART port
I experience a problem when the capacitor is fully discharge. When the program try to read from a UART port it stall on the read command and the application will not continue.If I put a delay before the read for the time that it takes the capacitor t...
Resolved! PWM input falling edge capture behavior
Hi,I'm following RM0390 reference manual's PWM input mode example for calculating frequency and duty cycle for incoming PWM signal. Basically I'm using TIM1's CC1 for capturing rising edges and CC2 for capturing falling edges. The question is that is...
What is the proper method to interrupt/signal that new information is ready between core M7 and M4 in an STM32H7 processor?
I am looking at the STM32H7 reference manual and STM32H745 code examples to determine how to transfer and signal new information between the cores. Currently I see two possibilities: Shared memory and a hardware semaphore/interrupt or shared memory a...
Resolved! Activating TIMER PWM mode with CMSIS. Need help!
Hi all! I'm fighting witn CMSIS, and now I'm triyng to start a timer in PWM mode. The MCU is a STM32F303CCT6, and the timer I want to use is TIMER3, activating a led on PA6. I didnt modify any clock, so I supose the MCU uses the HSI clock at 8MHz.Thi...
SDADC speed, accuracy and calibration.
Trying to get best of STM32F373CCT6 & its differental moded SDADC1 for a pressisios bridge type sensor.Datasheet's say that the SDADC speed limit is 50kS per second.Ive reached only 68uSec (~15k) for thisHAL_GPIO_WritePin(GPIOA,GPIO_PIN_4,GPIO_PIN_SE...
STM32F7 HAL_EXTI_SetConfigLine() causes the Hard Fault
STM32F7 HAL_EXTI_SetConfigLine() causes a Hard Fault whenever the parameter is one from the HAL_EXTI_GetConfigLine(). CubeIDE 1.2.1STM32Cube FW_F7 V1.15.0Nucleo F746Following is the sample of the sequence. This code retrieve the EXTI configuration of...
Resolved! STM32F3xx - Hardfault_Handler due to failed vector table fetch
First I want to say that I am a newbie in this field. I am trying to upload and debug a code on a custom-made board based on STM32F303CB chip through a NUCLEO-F446RE board. I am using Eclipse IDE (2019-12), a GNU toolchain and a SEGGER J-Link debuggi...
Resolved! How to configure PWM as Gated output?
Hi,I am using STM32F072VBT6. I need a PWM waveform output that is gated with a PWM output of another timer channel.I am using TIM3_CH1 as the master that will control the output of another PWM of TIM2_CH1. Please refer the image for clarity. I need w...
