Boot to RAM from SD card on STM32H7...

Greetings!I've got custom hardware running on an ST32H7. I'm trying to load an image from the sdcard into off-chip RAM for execution. RAM's at 0xC0000000, and I think I've set the MPU configuration correctly: // Region 2 is the external RAM MPU_InitS...

Shouldn't DMA_HandleTypeDef State be volatile?

Current structure is:typedef struct __DMA_HandleTypeDef { ... HAL_DMA_StateTypeDef State; /*!< DMA transfer state */ ... } DMA_HandleTypeDef;Interrupts can change the State value, but it's not volatile, so the co...

Delivery Time of STM32H743ZIT6

Hi, I would have a question regarding the lead time of the STM32H743ZIT6. We use the part in multiple boards in our platform which is currently in prototype stadium. Fro the next charges of PCBs we are trying to order some uControllers (STM32H743ZIT6...

Is it possible to run multiple MQTT clients on a single H7 using Netx Duo

I have a project where a single stm32h747 will be acting as a system controller for two groups of motor drivers. We want to create a client whenever a motor group is plugged in. This will ideally allow us to use functionality like the last will messa...

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...

ADC noise issue (pin PA0) STM32F746 microcontrollerPlease explain the presence of increased noise at the PA0 pin of the STM32F746ZGT6 microcontroller in the ADC mode.ADC parameters:• Clock frequency - 13.5 MHz (with a prescaler 4)• Sampling frequency...

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...
