STM32 MCUs Products

Hello there, in my project explorer, the projects pilled up quite(see picture) a bit and it's annoying when i have to find the existing project from the list. Is there a way to manage them, to create folders where i can group them?

Using RTC Alarm as a 4 hour timer. Getting the current time using HAL RTC API, adding 4 to the current hours value and setting the alarm for that time by keeping the minutes as the current time. The Alarm interrupt is late by 2-3 minutes. Why?

The STM32F030CCT6 is put to Stop mode. It wakes up on getting the RTC ALARM interrupt which is being used as a 4 hour timer. (The wakeup timer of RTC is being used for another purpose hence this work around). On getting the interrupt, the MCU calcul...

STM32F072 I2C slave Receive callback

Hello, I am using STM32F072. I want to use device in I2C slave and using HAL driver. I am looking to get callback when complete data is received at I2C slave side. I found function HAL_I2C_Slave_Receive_IT() which is kinda similar but here I need to ...

STM32F373 I2C slave transmit clear TXIS flag problem

I need to implement an I2C slave in an STM32F373 and I'm stumped by the documentation in the reference manual (RM0313 section 24.4.7) figure 176. The NOSTRETCH=0 with 1st data flushed looks to be exactly what I want to do but the documentation in 24....

DMA data loss when changing PWM frequency during the DMA reading

Hi there,First time working with DMA here and I'm getting data loss when the frequency of a PWM signal is varied during the DMA reading. The DMA request is triggered by a 16MHz clock. I'm using DMA2 on STM32f429zi.The DMA direction is peripheral to m...
