STM32 MCUs Products

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...

STM32F0 increase programming memory and ram size

In my project I'm use STM32F030C8T6TR MCU in this MCU programming memory is 64kb and ram is 8kb how can I add external memory and ram to MCU?​
