Datasheet Accuracy Specifications
Hello,I'm doing some preliminary error budgeting for a piece of ATE that may include an STM32 MCU and was curious what the uncertainty of your public accuracies was? Appreciate it,Bob

Atollic TrueSTUDIO: Why is there a question mark at the file icon?
As shown in the picture, there are question marks at the file icon. Why is that so? The build icon greyed out as well.
Is it possible to use an FMC SDRAM - code execution AND data storage
Hi all,We have connected an 64Mb SDRAM to the FMC interface of an STM32H745, it is available at 0xC0000000.We use the default FMC mapping. Is it possible to reserve an area in the SDRAM for code execution and access it at 0x70000000 (size of 512K). s...
SDRAM HardFault

How to dump the media files (Images- png,jpg,bmp), (Video files-avi,mp4,emf) ,(Audio files- wav,mp3,bin) from workspace to EXTERNAL QSPI MEMORY (MX25L51245G).
Hi STM Community,I want to write media files [Images- .png ,.jpg,.bmp), (Video files-.avi,.mp4,.emf) ,(Audio files- .wav,.mp3,.bin)] to External QSPI Memory. I found that, we can write media files to external memory from USB Key and SD Card. But, I d...
Resolved! Starting a timer on a GPIO input rising edge
I'm trying to set up TIM2 timer on my NUCLEO-H743ZI2 board (STM32H743ZI MCU) to start TIM2 timer on a rising edge of a GPIO input pin. I'm using STM32CubeIDE with STM32CubeMx plugin. Is it possible to set up the hardware to start the timer automati...
STM32L4S9 SAI Configuration Full Duplex
Hi,I would like to use the SAI as full duplex slave mode with I2S/PCM protocol.I'm not sure about the configuration and which pins are TX and RX when using Cube. In the parameter I can set the audio to transmit or receive.In this case SAI_SD_A will b...
STM32F411CEU6 no longer blinks blue LED when connected, I broke it?
Am new to the STM32F boards. Have been using an STM32F103C8T6 with success using Arduino. Was attempting to get the F411CEU6 connected and "did a lot of things" to include things with the ST-Link. Now when I connect the 411 via USB the blue LED no lo...
SWD connexion for custom board
I have an ST link V2 and a custom board running at 3.3V generated by an on-board regulator powered from a battery. Google is sending me mixed messages about connecting VAPP (pins 1 and 2) on the ST link to VDD on the board. I'm a bit worried about de...
