STM32 MCUs Products

Is it possible to copy the code stored in the internal or external flash to the internal SRAM and execute it from SRAM ?

Can I use MCU's internal oscillator when communicating with GPS and cellular modules?

Can I use MCU's internal oscillator when communicating with GPS and cellular modules? I want to avoid connecting external crystals for the MCU since they generate noise, extra components, extra costs, and on top of that require PCB design constrains ...

Timer sample code for buzzer on STM32L432G

Can you please share me timer sample code for STM32L432G board.I have Sensortile board and would like to interface buzzer, so I need to add timer code to get timer cb to toggle the required frequency to get the proper buzzer sound.Also please suggest...

Hello. We use stm32f405 and voltage 1.9 V. At this voltage, timer 8 does not generate PWM at a frequency of 12 MHz. At a voltage of 3.3 V, the generation works.

Using HAL and CubeMX. APB2 72 Mhz. The timer prescaler is 0, the period is 5, the duty ratio is 50%. How to solve this problem?

HTU21D sesnor with Nucleo-L152RE

I am newbie to use Nucleo-L152RE board. I have a HTU21D-Temperature & Humidity sensor which used I2C interface to read the temperature data.So, with using the STM32CubeMX I have generated code for STM32L152RETx chip with UART2 (debug purpose) and I2C...

Float variables print on Debug UART

With the help of STM32 CUBEMX generated basic code for IAR-EW and I have design a small code to print float variables on UART for debug purpose in STM32F413RH. This is working fine in IAR-EW but same things when I used in Atollic TrueStudio it is not...
