I want to use the internal RTC on the STM32U575 to maintain the date and time for an embedded application even when the main power supply is off. The VBAT pin of this chip is connected to a coin battery. However, I have observed that every time the m...
Hi All,I want to use two ADCs on STM32H7 configured equal, but using one DMA each, and measuring on different channels. However it seems like the ADC3 have options ADC1 and 2 doesn't have. In this case DMA continuous request.Is this intentional? A wo...
we are using the stm32f7508-dk board , we added one function in while and timer 3 interrupt enabled in that code .when debugging the code continuously its going to interrupt , the code in while function executing if i add break points. i f i remov...
I'm trying to debug a problem by which, if the EOT IRQ is enabled, an SPI slave enters an endless loop of ISR executions. I suspect it might be related with how IRQs are generated. According to the H7 user manual: The TXP interrupt is generated whene...
Hello STM32 Team.I using uart1,3,6 setting for baud rate 115200,Uart3 setting is it. huart3.Instance = USART3; huart3.Init.BaudRate = 115200; huart3.Init.WordLength = UART_WORDLENGTH_8B; huart3.Init.StopBits = UART_STOPBITS_1; huart3.Init.Pa...
How to interface Bosch BME688 sensor to stm32f446re via I2C
I tried to overclock STM32G030. I didn't need more speed and such operations should never be used in final product - only for curiosity.But it's 64MHz according to specs. I ended at 160Mhz. Room temperature, 3.3V power supplyTested with rather simple...
Dear all,I am new to STM32 development environment. I recently purchases STM32F407G-DISC1. I also purchased mini USB cable. When I connected the board to the PC, I can see that LD1 is on (RED). I can upgrade the driver for ST-Link as well. So, I am a...
I have spent all day on this. Everything looks good because I can run or debug the firmware from within STM32CubeIDE and it works as would be expected. However, after power cycling, the code is not running.I have checked that my interrupt vector ta...
