I set up EXTI so I get interupt on the correct pin GPIO B.6. But I cannot get it to wake up from stop1 mode. I call WFI and RTC wakes upp the processor regularly but EXTI will not. Reading the reference manuel it says any interupt should wake the pro...
I already installed the latest stm32cubeIDE(version 1.15.0).when I was trying to create a new stm32 project, the error present as below:So I want to install install software package first, but the help->manage embedded software package is no response...
Hi,Master:Question：When the finished product cannot be debugged with jlink, I want to save and trace the function stack information through the firmware. When there are some accidental exceptions, I need to use the function stack to more delicately l...
Hello all,I am attempting to read the direction bit and have observed a surprising behaviour. Let’s say my encoder was set to the reverse direction. If I attempt to move the encoder in the opposite direction, the direction bit doesn’t update until I ...
I could cry... ("rrrr", the more I dive into latest STM MCUs - the more I get frustrated - LOL)The datasheet for STM32U5A5, LQFP64 package, tells me: there are PB15 as SAI2_SD_A and also PC12 as SAI2_SD_B.But the CubeMX does not let me configure thes...
Hi ST,i have an inverter project designed with stm32g474xx and there is a "h-bridge" topology in the system.Can I create a uni-polar PWM to get three-level output while controlling this topology with hrtim1?Can hrtim1 create uni-polar pwm outputs (18...
I have a board using STM32F103CBT6 chip. After flashing the board once (through CubeIDE v1.14.0 with ST-Link v2) I cannot flash it again and keep getting the message "No target found". Here's a snapshot of the chip circuit: When I power up the boa...
void BSP_SPI_Write(uint8_t ValueL, uint8_t ValueR) { char txData[2]; char rxData[2]; txData[0] = 0b10101011; txData[1] = (uint8_t *)&ValueL; HAL_GPIO_WritePin(GPIOD, GPIO_PIN_2, GPIO_PIN_RESET); TIM6delay_us(10); HAL_SPI_Transmit(&hsp...
From what I understand, a STM32L433RCT3 MCU powered by VBAT pin will shutdown except for RTC and backup registers.1. I'm wondering if the RTC Alarms can trigger during the VBAT period?2. Will any code execute from the RTC Alarm interrupt during VBAT?...
Hello everyone, iam using nucleo-U575ZI-Q board and trying to do Flash programming. I want to write the data in to the flash and read the data from the flash. I've written the code but something is going wrong with it. Could someone please help me in...
