STM32 MCUs Products

I would like to do an absolute minimum bare bones project. Could someone direct me to a C project that just shows how to make a port input or output, and how to toggle the port high and low?

I've got a MCBSTM32F400 development board. Every "getting started" thing I've found (blinky, for example) has like 900 files in the project, and 150,000 lines of code. This is so disheartening. I got into microcontrollers because of their simplici...

Connecting DAC to OPAMP in STM32F303K8

I'm curious if there is any way to configure the STM32F303K8 such that the OPAMP is driven by an internal signal, preferably one of the DACs.I'd like to use it as a headphone amplifier or an amplifier for a tiny speaker, but not sure if it's appropri...

Does the ADC conversion time need to be shorter than the timer interrupt if the ADC is driven by a timer interrupt?

I am driving ADC1 using the timer interrupt from TIM2. At the moment it is only converting one channel at certain intervals. The ADC is set up with the following:ABP2 peripheral clock = 84 MHzPCLK2 divided by 8Timer 2 trigger out event as sourceSampl...

Low power modes when using external SRAM and FMC

What is the best way to handle entering and exiting Stop1 and Stop2 modes while using external SRAM in my application?The problem I seem to be having is when I leave my lines configured for the FMC controller when entering Stop1 or Stop2, my current ...

How can I detect if there is CAN-bus activity going on, when the packets aren't for me (they're filtered away)?

I am working with the STM32F446-microcontrollers and I have several of them connected together through a common CAN-bus. I am using packet filtering in a standard way to ensure that only the intended microcontroller acts upon a specific packet. Howev...

STM32L4 Internal RTC Backup Domain Access

Hey, I have problem when add some feature tamper using alternate function from STM32L4 MCU's pin. When the tamper active, internal RTC was reset. even my config for tamper configuration 'no erase' was set (enable). Can help me ?
