I'm new to the STM32Cube series, and I'm using the STM32Cube MX L4 chipset. I believe I've done everything that online tutorials, examples, and the actual specs demand, but when my code issues HAL_CAN_AddTxMessage, my ISR never gets called. What am I...
Hi guys,I need a help..and sorry my bad English.I would like to know how i can generate a pwm from one stm nucleo H7A3ZI-Q and read the duty cycle (generated from the first STM32) from another stm, implementing everything via simulink if possiblethan...
I am trying to configure a PWM output pin. Ive managed to get it working, however the results are not as expected, and i cannot understand whats happening.Currently my timer clocks are running at 64MHz.I've setup a timer with the follow values, and i...
Hello,During code execution I would like to monitor the available memory. Is there a default function available to check the available RAM memory? Thanks
Hey!I have been with a problem with the stm32l452 comparator for a few days now and I can't figure it out. The interrupt of COMP1 triggers on both edges rather than rising edge.I tried differents configurations but main is the following:hcomp1.Init.I...
If I understand STM32H7xx datasheet, I2C peripherals support up to 1 MHz (FM, FM+), 'officially'.I would need an I2C with 5 MHz SCL clock.I tried and have 'overclocked' I2C with 2 MHz which works fine.Based on the clock configuration (e.g. a 50 MHz P...
HelloI need to interface a STM32H743 with a STUSB1602. I want to port STM32F072_MB1303_DRP_SRCING_DEVICE example to my STM32H743 and use it to control 5x STUSB1602. It seem like this example uses RTOS- Has anyone successful done this or can they reco...
I'm struggling to get DMA working on a PWM Timer. I've read just about everything i can, but not having any luck get it working.Running this code.. produces a PWM signal as expected on the output.TIM1->CCR1 = 50; HAL_TIM_PWM_Start(&htim1, TIM_CHANN...
HelloI have a const variable located in the internal flash memory. When I directly access this variable in flash, the read operation returns always 0 (even when the content of that location in flash is not 0). When I change the code to first copy the...
I would like to trigger ADC conversions using a timer so that I can get the time associated with each sample. This is so that I can plot voltage vs time like an oscilloscope.According to the datasheet, it seems like the maximum external ADC trigger i...
