STM32 MCUs Products

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?​

Getting wrong value from ADC - STM32G431KBT6

Hi everyone,I'm getting weird values from ADC in a new board that I developed. It looks like it has an offset on it, but a big one.The analog signals arriving in the pins are ok. I tested with a scope. To make sure there was nothing wrong with the an...

SCTimer/PWM equivalent in STM32?

I have a circumstance where two PWM outputs are required, and they must be precisely coupled together. A number of the other big guy's LPC micros included an SCTimer/PWM (that's State Configurable Timer...) which, without too much magic, allows a fi...
