Good day,We are working on an Audio application and we would like to use the Nucleo-H743ZI board and the libAcoustic_EC_CM7F_GCC_ot.a library but we have hit a bit of a snag and I am hoping someone will assist us with solving the issue.We bought the ...
Posted on February 01, 2017 at 10:10Hi! I am using stm32f4-discovery to start working with mass storage clas and internal flash. I have tried different ways but every time I've had the same resault. I can see storage device in My Computer but can't ...
I have been exhaustively trying to program my STM32F7xx microcontroller to use DMA to transmit to UART. Three things are going on and I cannot explain or understand why this is happening, and hope somebody can help me out with this issue.In the main ...
Posted on May 09, 2018 at 17:16I am currently using stm32h743ZI nucleo board with a Sparkfun SD/MMC card breakout and SanDisk class 10 8 GB SDHC micro sd card (with adapter).I have a similar working project for F767zi nucleo, am now trying to port i...
Hello,Has anyone heard anything about a H7 class device with 2x HS USB? I would like to stick with ST parts for an upcoming project but I need 2 x HS USB. The i.MXRT series has this feature but the documentation for these parts is terrible...Will the...
Hello,everyone,I have a problem when I want to use STM32Cube_FW_F4 Demo Project to develop a USB MSC Project with Freertos. The main problem is it seems that the HAL_HCD_IRQHandler() just can not occur,but when I did not use Freertos, which worked j...
I have only managed to find examples using HAL libraries which I am not fond of. I Have been looking through the LL header files genereated by STM32cubeMX for any flash programing information at all but I was unable to find any. If there is not supp...
The USB-HID ST library comes with an example of Mouse device that I have adapted successfully.However it only has a single Input endpoint to send reports to the Host.I am mainly interested in OUT endpoint for communication Host to device.Does anyone ...
Hello. I am using STM32F4279ZI MCU with FreeRTOS. I want to compare efficiency of bare-metal and OS based program implementation. While doing some tests I have noticed that the same function called from bare-metal aplication is much slower than that ...
I have an application program running on a Nucleo-H743. While most of other components are working, I'm having trouble with onboard USB to work.The USB handling is ported from CDC_Standalone application example for EVAL from STM32Cube_FW_H7_v1.3.0....
