I'm trying to use the factory bootloader from STM32l486 microcontroller without success. From the application code, the MCU jumps to the bootloader code located at beginning of the system memory using the following piece of code adapted from what I'v...
Hi guys,I'm looking at a number of ways to interface 8xPDM microphones and one of the ways is using an STM32H7 with it's SAI/PDM interface. According to the documentation (AN5027, 4.3.1), I should be able to select up to 8 microphones in the H7 SAI1_...

I bought a second non-working used 3D printer with the expectation of repairing it. Turns out the MCU was destroyed - it actually had holes blown in its casing! I bought a few new MCUs of the exact same type, and replaced it. I can successfully put t...
There bug in STM HAL Lib generated by cube mx. Problem: I am using usb communication on STM32L433. I have high speed traffic both direction on the same endpoint. USB is stopped in one of the direction, and doesn't transmit/receive data any more.Why:I...
Hello,I am trying to overcome some strange issue using IAR when starting freeRTOS thread from main.I have used the following example for usb\en.stm32cubeh7\STM32Cube_FW_H7_V1.3.0\Projects\STM32H743I_EVAL\Applications\USB_Host\HID_RTOSIt detects a HID...
Posted on July 05, 2018 at 08:56 Hi all, I'm having a strange problem with a design using the STM32F072V8 MCU. MCU operates at 3.3V. We have a USB connector internal to the product, solely for programming the MCU via DFU. I have the BOOT0 pin...
I am currently attempting to use the USBD drivers for the STM32F765 in order to communicate over USB C as a virtual com port. I get to the point where my computer recognizes the device and the driver that is necessary, therefore the control transfer ...
I see that there is a function to write SDRAM ( HAL_SDRAM_Write_32b ) but no FLASH.I want to take data from ADC array[2000] and save so I do not loose when it is powered down.And of course recall / display it later.
Hi,I need to write a bootloader which will load the new program from a USB memory stick.Unfortunately I cannot use the ROM based DFU bootloader.The bootloader would need to be held in FLASH and protected against update. Easy enough.I believe that the...
