STM32 MCUs Products

Hi, I want to write scrolling data to RTC Backup reregister. But how can I do this, I have no idea. I looked at the hal library but it doesn't support float data.

Moving SystemClock_Config Causes Strange Erros

I know this is a vague question, but it's a very strange problem I'm facing. My application (based on STM32G0) is working fine. I used CubeMX to autogenerate all the code, and have been building on top of it. Now I am looking to clean things up a bit...

Stm32g0 production programmer

Any recommendation for production programmer for stm32g0? Volume range from 2k to 5k per run. Thanks in advance.​

Any way to lower RAM in order to add to FLASH?

Hello All.I am working on a small project for a friend while learning the STM32 environment.The project is currently using a STM32F030x4 in a 20 pin TSSOP20.I have committed a sin; I have run out of Flash Memory.Is there any way to reduce the RAM all...

Has anyone gotten the boot0 pin to work on an STM32G071? (SOLVED)

It goes into the bootloader only with a virgin part, once programmed once (using the bootloader) asserting boot0 during a power on or reset runs the application code not the bootloader.

STM32 interrupt service routine and volatile variables

Hello,I'm using an stm32f411 which is a cortex M4 device.In my application I have an interrupt from an IMU in a 400hz frq. Every time the interrupt is called I want to read data from the sensor and process it using a filter function.I have a few ques...

For ADC input, my input signal is sinusoidal with no DC, that is, it has positive and negative value. Is it possible to convert a negative value without problem?

In the document, the input level is limited by Vref+ and Vref-. But Vref- seems to be tied to GND in general, which implies a negative value cannot be converted without problem.Can Vref- be connected external -5V or -3.3 V for handling a negative val...
