FILE *stream via USART
Hi,I'am reading data through USART1 and USART2. I am sending the data over USART3 using printf. It works for a while but then stops.Here is my code:FILE *stream; char *buf; size_t len; void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { if (...
Resolved! Changing of ADC control and configuration bits of STM32L475
I have found that from the ref. manual, certain bits of ADC control and configuration bits when ADC enabled but in the drivers provided by the ST showing that they are changing only when the ADC is disabled. For reference, I have attached the screens...
Resolved! Is this chip a genuine stm32 chip or clone?
I've been having a few problems uploading code to that chip ( having to press reset every time in addition to the inability to use the "ST-Link (GDB server)" option for debugging) and i was wondering if that was due to the fact that it might be fake...
Interrupt safety issue in HAL_I2C_Mem_Read_DMA()

STM32 and json
Hi Guys,I´m working with STM32F429ZI and I´d like integrate a project with json library. What is the best way? Are there ST json library? to STM32?Where can I find examples?Thanks,Geraldo.
occurred fault during HAL_RCC_OscConfig
Hi,I am using ST32F446RC.After jumping from bootloader to application, an fault occurs during clock setting(HAL_RCC_OscConfig function). The bootloader code and application code use the same clock code as below.static void SystemClock_Config(void) {...
Interrupt priority register addressing
Hi All,I think understand the concept of this, what I am not 100% sure about is how each NVIC_IPRx entry relates to an actual interrupt.Is it directly referenced to the 'Priority' number in the Interrupt Vector Table ?So for example just looking at t...
Extended CANBUS example L4 or H7
Hello,In my project I must use extended CANBUS protocol on STM32L496 and STM32H743 microcontrollers. Does any one have example how to use it ? None on STM examples comes with extended canbus demo, googling also did not give any results. I have workin...
We are using STM32L072KB MCU in one of our product development. Currently we are facing current consumption fluctuation problem in STOP mode of operation. (0.31uA to 0.61uA). What would be the root cause of this type of issue?
