Trouble with CAN Interrupt and Free RTOS
I am having issues with the use of HAL_CAN_RxFifo0MsgPendingCallback. I've set every configuration (filter, start, interrupt, notification, and priority), but the function doesn't seem to be called at any time.Most of the code is generated from the c...
SPI TransmitReceive wrong behavior
Hello ST expert.I'm trying to create SPI communication as shown in the CubeMX image.and the following code/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c ...
Resolved! VREF as comparator input fails but equivalent DAC input works just fine. Why?
I have a signal biased around the VREF output (2.048V) of an STM32G4. I have a comparator (COMP7) peripheral configured to compare this signal to VREF and it fails. If I set the second input of the comparator to DAC2 and set the DAC2 output value to ...
STM32G051G6U6 IWDG not refreshing
Hi,I am facing an issue with IWDG in STM32G051G6U6.HAL_IWDG_Refresh(&hiwdg); not refreshing IWDG and the core resets after IWDG overflow time.IWDG overflow is set at 13Sec (varying wrt prescaler) and I am refreshing it at every 1 sec.Counter presc...
Resolved! Simple UART problem STM32H753
Hi,I'm relatively new to the STM32 world and I'm becoming frustrated that I can't make a simple UART work. No DMA, no interrupts just trying to send bytes out of the UART and then receive them. Here is my setup code: void UART7_Init(void) { GP...
SPI lower harmonics problem with XPT2046 touch sensor
I had EMI problems interfacing with my 4.0" ILI9488 v1.1 display over SPI. Having a long cable (about 30cm) display and touch works when powered using ST-Link V2, but when i powered it using a generic 24V PSU, the display and touch is not working all...
Resolved! STM32H7 ADC calibration, I don't understand
Hi all,I am experimenting with H7 ADC (after having tried the G4 ADC).I see in the HAL that the calibration, HAL_ADCEx_Calibration_Start(), for H7 MCU wants a parameter more than G4. One should specify ADC_CALIB_OFFSET or ADC_CALIB_OFFSET_LINEARITY.I...
Selecting RTC Internal wakeup line
Hi everyone!I have an u585 related question:Can I configure RTC internal wakeup line other than PWR_WAKEUP_PIN7_HIGH_3 ?In all u5xx examples used this line, but We have an external wakeup source on PB.15.I can't change it in CubeMX and I can't find ...
Resolved! CANFD Transceivers for NUCLEO-H563ZI and NUCLEO-H753ZI boards
Hi,Starting a new project involving CANFD with the NUCLEO-H563ZI and NUCLEO-H753ZI boards, and am looking at how to get started quickly.Can anyone point me to a ready made shield with appropriate high speed CAN FD transceivers?Thanks,
