STM32 MCUs Products

Resolved! Hello. I am developing with STM32G070R8T6. It seems that there is interference between PA10 and PB15: whenever PA10 goes high, PB15 (with external pull-up) is driven at 1 V. This happens even in reset, so it is not a firmware bug. No hw connection. Tks

Resolved! Code runs fine after `st-flash write`, but not after reset

I'm using the template code for the STM32F7508-DISCO from the STM32CubeF7 repository with the only change being that I add a LED toggle and a busyloop to an infinite loop in `main`. The startup code and everything else is per the template.If I flash ...

Resolved! what is the the hardware fifo size of STM32f103CB and how to know whether the FIFO is empty or full?

HiAs the title mentioned, I can't find relevant information in the datasheet.I get some problem when using UART. I have two chips, the master chip transmits packages to RS485 Bus line, and the slave chip receives it then transmits the respond(UART1),...

Resolved! Hi, I am new to STM32. I am trying to get the RTC working on a nucleo F302R8 board. But the seconds are giving weird returns. I am not sure that minutes work properly either.

Here is the RTC initialization code:static void MX_RTC_Init(void){ /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; /* USER CODE BEGIN RTC_Init 1 */ /* USER CODE END RTC_Init 1 ...

Resolved! hi sir How to check which GPOI pin is associated with I2C1 or USART1? question no2=> if USART use GPIO pin PA9 as USART_TX pin , then if i code to turn on LED on PA9 on different project will it work ?

i am using STM32F103c8 MCU

Resolved! Is there a way to flash two different programs on different sectors of the same Flash?

I am developing an application that requires over the air firmware update, but my MCU's Bootloader does not support this Task (stm32f446re). So I was thinking to do this :1)My main appllication will be located at 0x0800 0000 on the flash2) At some po...
