Hi,I am trying to integrate ESP8266 wifi module with microcontroller ( STM32F429IGT). wifi module (ESP8266) is not responding. when I send the AT command i am receiving the same AT command which I sent instead of getting response message. Please help...
Question and comments about NAND driver
I am using STM32CubeMX version 4.26.1 - haven't upgraded to 5.0 because my customer won't agree to yet, as there is some stable code produced by the older version which they don't want to regression test right now. The device is the STM32H743IITX, l...
Advice for speeding up USB writes?
Hello, we are using an STM32F7 and are saving image data to USB, using mostly the BSP code (disk_write in usbh_diskio.c -> USBH_MSC_Write in usbh_msc.c and so on). However we have found it's quite slow, 6-7 seconds to save one 400x400 image. I've s...
Cannot boot when Read Out Protection Level 1 is set.
Hi,I am having a problem using Read Out Protection on the STM32F405VE processorMy firmware has a proprietary bootloader which is stored at 0x8000000. It basically checks to see if a USB OTG lead is plugged in and if so attempts to access a mass stora...
Combined PWM: Inconsistend RM description and error in STM32H743xx.h
Thank you for the new "Combined PWM Mode" for the main timers... . This really was missing in STM32F4, creating 2-3 phase shifted PWM signals with just one timer... . This is now VERY nice with STM32H7.But the discription in RM (July 18) 37.3.13 is s...

Hi,I am using STM32L031K6 MCU and SW4STM32 IDE for development. I want to read/write specific register value of i2c slave device from MCU(i2c master)Below is a code I am using.#include "main.h" #define I2C_ADDRESS 0x3c #define MASTER_BOARD #...
STM32L4 USB Host communicating with a custom class device with multiple interrupt out endpoints.
Hi all,I am using the Nucleo-L476RG dev board and am using it as a USB Host to communicate with a custom vendor device which has 4 interrupt IN endpoints and 4 interrupt OUT endpoints.My code has been generated using CubeMX and I have generated a cus...
STM32H7_HAL Ethernet has problem yet.
Dear Imen,Thanks for your replay.I modified my project file using your new library file(ethernetif.c)And I was testing during two days.But, It has a problem yet.Previously, there was stop the ethernet in minutes.But, there was stop the ethernet in ho...
Unable to install driver for STM Device in DFU Mode.
We have a customised PCB and would like to have the feature of being able to flash the firmware using USB. So, we have the USB DM and DP pins wired to PA11 and PA12 pins (of STM32L152), respectively. We also configured the BOOT0 to HIGH and BOOT1 to ...
