What to do with unused IO's
Here in the below image from the Cube MX it suggests that, SET all the free pins as analog (to optimize the power consumption). How does it help. Also is it applicable to all the controller families?

External resistor for my oscillator design
Hi, I have a question about this highlighted text in the AN2867 document refering to the "calculating external resistor" paragraph As I understood the condition to use a Rexternal is "if the power disipated in the crystal is higher than the value spe...
Leaving Stop 2 Mode on the STM32L4P5 causes hard faults
I have been trying to figure out why I keep getting consistent hard faults when trying to access peripheral instances after waking from Stop Mode 2. Here is the code I am usingFor entering stop mode:static void SystemClockConfig_STOP(void) { /* ...
STM32H750VBT6 - USB Host MSC Not Detecting USB 3.x Devices
Dear ST Support Team,I am currently working on a USB Host Mass Storage Class (MSC) implementation using the STM32H750VBT6 microcontroller.:white_heavy_check_mark: The configuration is done using STM32CubeMX (version: [ V6.14.1]):white_heavy_check_mar...
STM32F030 Reference Manual - SW AP Registers Documentation
I was comparing the STM32 Debug Support documentation (Chapter 26 in RM0360) with official ARM documentation and noticed something that I cannot explain. The documentation for the SW-AP registers appears to be wrong. It is simply a rewording of the d...
Configuring STM32L431 SDMMC for high speed data transfer using DMA
Hello everyone,I have been working with the STM32L431RCTx on a project where I need to log audio data to an SD card. I have attempted to do multiple things unsuccessfully and would really appreciate your help to see where I am going wrong. I am new ...
SPI Communication with AD5592 ADC/DAC
Hello, I'm attempting to work with the AD5592 ADC/DAC in SPI mode and am unable to confirm communication. I'm attempting to read and write to single registers to determine whether communication takes place since I don't have an oscilloscope or logic ...
Resolved! Can I use OCTOSPI as a Classic SPI?
Hi. I am using STM32H735VG for SPI communication with external ADCs.But I want to add external ADCs and I already used all 5 SPIs.So I will use OCTOSPI, can OCTOSPI play the same role as classic SPI?In menual, OCTOSPI in indirect operating mode works...
Pinout to read stm32F103zet6 using ST-LINK
Hi,I want to know pinout to read flash from CHIP stm32F103zet6 using ST-LINK.Can someone provide it, im new on STM32 chip. Thanks.
Cofiguration UART4 from STM32H753ZIT6 Development module
Hi, I’m trying to configure UART4 on the STM32H753ZIT to work with a USB-TTL converter for data transmission and reception. I can see that the STM32 is sending data, but the TTL converter isn't receiving it. I've attached the code file and the output...
