Hi,I want to know whether stm32f030C8T6 has unique device ID?

Does it possible to write a byte of values to the flash memory of STM32F030CC

Hello all,Can anyone in his forum to let me know whether can be write a byte in to the flash memory of the STM32F030CC uC, it always asking to increment the the write size as '4' bytes, if I hchange the code to write as a byte or even a two bytes the...

Hi, For the controller stm32G071RB, formula for "Timer clock frequency = (Microcontroller frequency / (prescalar Value+1))" is available in datasheet. I need similar type of formula (Timer clock frequency) for stm32F030CC controller.

Which MCU support iAP2 [iPod Accessory Protocol] protocol?

Hello,Where I can use iAP2 protocol means which MCU support iAP2 protocol? and How can I flash iAP2 programming code in MCU?Regards,Bhautik

Method to control the full scale output of the DAC (volume control) ?

Hello, I use the DAC together with the DMA in circular mode to generate a sinewave of a few Hz. A buffer is filled with the predefined values of one sine period. The frequency is adjusted with the DAC clock and the sine amplitude by updating the sin...

STM32H750VB page size for flash erase - is it 128K, and if so, are there ways to partially erase the flash for persistent data storage?

I have application that fits comfortably in 128K bytes and has some persistent storage (data tables that are occasionally written by the application journaling-style, and occasionally a need to erase some of the data to accommodate more Here is my qu...

Are there any flavors of STM32F4's or their alternatives available anywhere?

STM32F427ZIT6 lead time and availability issues

I have a product line using an STM32F427ZIT6 MCU which has been in production for several years. Suddenly it seems to be unavailable. Both Mouser and Digikey have zero stock and cannot even quote a lead time. Our production will be halted very soon. ...

RNG clock error on NUCLEO-L4A6ZG

I am trying to use the RNG on the STM32L4A6ZG but every time I enable the RNG clock RNG_CR |= RNGEN the RNG_SR shows CEIS and CECS.The AHB bus is at 80MHz and RNG_CLK is at 48MHz. I've tested with configuring the RNG_CLK to come from either the HSI48...

Hi, I'm testing libopencm3 libraries on a stm32f103c8t6 board. I have an erro that seems the st-flash tool is not able to record in the SRAM when I use a vm Debian GNU/Linux 10 (buster) , but when I use a VM with arch Linux the process is succesfully.

Attached images of both systems and I really appreciate suggestions to understand and be able to solve the problem in debian.
