When I first glanced through the STM32G474 datasheet, I saw VREF+ and VREF- on pins 43 and 44 on the LQFP128 package. "Cool", I thought, although I had no significant need for an actual VREF- pin.However, when I was making a schematics symbol, I noti...
When ever I configure HSE in my ioc file for my custom PCB my code stops at SystemClock_Config() or HAL_Delay(). One time when I replaced 48Mhz crystal oscillator with 32 Mhz my LVCU code worked on HSE but it was considerably slow than HSI even on 1...
Good day,I'm experiencing an unexplained bus fault when the MCU writes to unaligned (not aligned to 32-bit) addresses in the OSPI memory region. I've written a minimal implementation that shows where the issue occurs. See below.I'm using the STM32U58...
Hey,I have a chinese STM32H743 Board, with a 25Mhz Clock Source and sdcard 3.3V VDD.my clock settings:my SDMMC1 config:static void MX_SDMMC1_SD_Init(void) { /* USER CODE BEGIN SDMMC1_Init 0 */ /* USER CODE END SDMMC1_Init 0 */ /* USER CODE B...
Hi all, I am using the NUCLEO-H7S3L8 board, and trying to boot MCU from the bootloader.Based on the reference manual, the conditions for that at the MCU reset :PRODUCT_STATE = OpenNVSTATE = OPENBOOT0 = HighI checked PRODUCT_STATE = Open at the option...
I'm working with the STM32H730VBT6 and I'm currently using the stm32h730xx.h CMSIS header file, but there's also the stm32h730xxq.h in the cmsis-device-h7 repository. I assume I'm using the correct header file for my microcontroller (pretty sure Cube...
If the PDR_ON connector is connected to the GND, the VBAT function may not be available.What is the VBAT function?To use RTC, a coin cell is connected to the VBAT connector. Is there a problem if the PDR_ON connector is connected to the GND?I am usin...
Hi Team, We are using the STM32H753 in our design.For the signal quality, we are adjusting the LSE drive strength.Below are the four options available in drive strength,low drivemedium low drivemedium high drivehigh driveKindly let us know drive curr...
I'm using an STM32H725 to communicate with an i2c sensor. I'm using the I2C4 bus with the HAL DMA functions. I also enabled the BDMA channels for the rx and tx and respective interrupts. The problem is that the complete rx/tx callbacks are not trigge...
Hello,I am working on a simple project at STM32L476 NUCLEO which includes ADC1 + TIM6 + DMA1. No libraries are used.I am facing the problem where I need to manually set ADSTART bit after each EOS, as it seems it gets cleared and no further conversion...
