As reported here, this is obviously incorrect.Also, this has been already reported by Uwe Bonnes for 'F411/RM0383, which has indeed been corrected in the registers description, but the GPIO register map still contains the incorrect value. So, could S...
The output pin in question can be configured as LPTIM1_OUT and I know how to configure the LPTIM1 but I'm afraid I'll endup with LSE/2 as a clock. I need the LSE clock source to be connected to that output pin 1:1.Besides using the LPTIM1 isn't there...
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...
