UART4 and UART5 Receive DMA interrupt on STM32F767ZI

I am using receive DMA to mange reception of data on UART4 and UART5.The setting of both UARTs is identical. UAERT4_RX is using DMA1 Stream 2UAERT5_RX is using DMA1 Stream 0I’m using halt transmit, transmit completed callbacks and idle interrupt to m...

float argument inside function stopping the infinite loop. screen sorts and file are given below. Edit: mcu I'm using is stm32f411re .

if I give argument like above picture infinity loop stops workingbut if I give the number num inside function the instead of giving argument then its working fine.If I give int instead of double as the datatype of argument then also it's working.Plea...

During the test, we found that the reference voltage of DAC channel 1 for STM32L4P5is 3V，while the VREFBUF for channel 2 is 2.048V，they are not identical，and the VREFBUF->CSR value is 2.

Are there any DISCO or EVAL boards for STMH7 MPUs that offer access to an unused I2C bus for external peripherals?

I might be missing a trick here, but it seems that most (if not all) DISCO / EVAL boards expose the same I2C bus externally that is used to communicate with onboard peripherals.This makes perfect sense with DISCO boards as they are small / low cost. ...

STM32H75x Dual Core Application with external SDRAM issues.

Hello All,I am developing a system based on stm32h757 dual-core M7 480MHz and M4 240MHz with external memory 4MB SDRAM. I would be glad to receive a recommendation regarding the right implementation. Firstly, I plan to connect external memory to M7 s...

HAL_Init initializes Systick, then SystemClock_Config changes the clock?

In the cubeMX default code the order is:HAL_Init(); and then SystemClock_Config();HAL_Init() sets up the Systick Timer with HAL_InitTick().Afterwards SystemClock_Config changes the Clock setup (to HSE in my case), but HAL_InitTick() is not called aga...
