Hello All,I'm trying to keep my MSC + CDC USBX connection alive on my STM32U575. When I connect the device via USB cable, Windows Explorer opens and displays the files on the W25Q NOR Flash. I can select a file and open it from the flash. I can al...
Hey all,I would like to confirm some current consumption figures present within the STM32N6570 datasheet.I am particularly curious about the current consumption numbers in the various sleep modes.Table 31 (Current consumption in Run mode) suggests ID...
Hi, I'm trying to get a PWM output that changes duty cycle on each period with DMA in circular mode. I have seen other similar posts (ultimately I'd like to control a WS28 LED with 800kHz), but they are for other MCUs and everything is different in t...
I'm planning to connect 40 LED with a current of 20mA (total 800mA) to 40-gpio pins of STM32G4 device. The pins will be configured as Open-drain so the 20mA LED current of each pin will flow through an external resistor and the internal low-side NMOS...
Hi all,I a developing a custom product were the partition is like Bootloader + APP1 + Partition 2 , were I Integrated the DFU library into bootloader and which is successfully enumerated in PC without any errors. My goal is do the flashing .bin file...
Hello all, I disabled the M4 core based on the tutorial by ST Employee mEALLEm, I pressed Apply, saw the option byte successfully programmed notification, but I have been waiting for MCU disconnect notification for 20 minutes now. The LD4 keeps blink...
For community awareness:Unless otherwise stated, STM32 GPIOs do not have partial-power-down / Ioff / back-drive protection.Example: If VDD=0V (or VDD unpowered) and a GPIO is driven with 3.3V, then excessive current may flow into the GPIO.This includ...
We are currently working on a project using the STM32H750IBT6 microcontroller interfaced with a single-bank Quad SPI NOR Flash (MT25QL512ABB) on our custom board. The QSPI interface is operational.However, we are facing an issue with the external loa...
i use stm32h750 as a decoder to translate use audio data into i2s 16bits 48khz data.however, when i use usb_otg_fs, everything works properly,but when i use the same configration and only switch to usb_otg_hs,some problem has occured. i use usb3300-e...
Hello,maybe this is bit off-topic, but does anybody know if it is possible to suspend an ERASE operation and write to another (previously erased) sector?I want to save a page in flash in case of a power outage and want to interrupt a probably ongoing...
