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...
Is there anywhere tog go to find out when parts that are not currently in stock will be?Some parts even though they are a new product line seem to have NEVER had any stock, and I though the covid supply issues were now sorted.Specifically at the mome...
Hello everyone,After several hours of searching, I haven't found a working example of an electronic schematic for interfacing a USB OTG port with an STM32 F7.Furthermore, the documentation provided "AN4869 Rev6" by ST is not clear enough to produce a...
Dear all, I need to know : 1.MTBF(Mean time between failure)2.Longevity.3.Shelf life or storage life.For component: STM32F446RET6I already try a online support, but the site show me “we can’t save this record ”.Can anybody help me?
Hi!I am still playing with the SAI of my STM32F446RE. It has one SAI (SAI1) which has two blocks, A and B.The idea is to use the two blocks synchronously in TDM mode to transmit in total 8 slots, 4 slots for each block.I can get it to work fine, thou...
