Dear All. I try to complier sample code from st at D:\STM32\STM32F746NG\STM32Cube_FW_F7_V1.7.0\Projects\STM32746G-Discovery\Demonstration\MDK-ARM On sample video from https://www.youtube.com/watch?v=R78zvO-s6H0 quality is good. but on complier and run sample code. quality not same. maybe need to modify some setting in coding.   Have… (Show more)

Few weeks ago I have started my first CubeMX generated project. Like always, my project is stored in git repository (locally). Recently, I wanted to extend projects functionality using re-generating option of CubeMX. Before this operation I have carefully commited my work. After CubeMX regeneration, with options like: "backup previously… (Show more)

Hi. I would like to use FLASH Data(Write, Read, Erase) in Flash memory of STM32F301C8T6. I follow to an example STM32Cube\Repository\STM32Cube_FW_F3_V1.9.0\Projects\STM32303C_EVAL\Examples\FLASH\FLASH_EraseProgram\MDK-ARM So It's not working. Please show me how I can do it.   Thank you. Best regard.

There were questions on how to read UART data using DMA in efficient way when you don't know how many bytes you can expect.   U(S)ART peripheral can work very good by using RXNE (Receive Not Empty) for each byte separatelly. In this case, every received byte is manipulated by CPU by jumping to appropriate UART interrupt service routine. To allow… (Show more)

Hello, currently im using B-L072Z-LRWAN1 send AT command to multitech gateway and server is loriot.io. And i cant get data at the server. Here some information: Firmware version B-L072Z-LRWAN1 v1.1.1 AT command:    AT    AT+CFM=0    AT+NJM=0    AT+DADDR=...    AT+NWKSKEY=...    AT+APPSKEY=...    AT+JOIN    AT+NJS=? (response = 1)… (Show more)

Hi, I have a problem with speaker and microphone USB descriptors working simultaneously on STM32F4 Discovery. PC discovers speaker OR microphone but not together. How can I get to work together? Code: //main.c   /* Init Device Library,Add Supported Class and Start the library*/   USBD_Init(&hUsbDeviceHS, &HS_Desc, DEVICE_HS);… (Show more)

More specifically we are interested in the AES256-GCM algorithm on STM32F777.   Looking at the User Manual (http://www.st.com/content/ccc/resource/technical/document/user_manual/group0/f9/6e/f2/a2/b4/ec/49/c0/DM00215061/files/DM… ) I conclude that for the STM32F756 the crypto hardware is used when using the STM32AccHwCryptoV3.1.0_Xy_C_O.a… (Show more)

Hello!   I am implementing a state machine which is driven by interrupts on the STM32F437IIT6. The interrupts occur as a result of using the HAL_SPI_Transmit_DMA() function.   While testing my program i have noticed that when i try to generate a new HAL_SPI_Transmit_DMA During the DMA interrupt  it doesnt work.    Please note that the spi-dma… (Show more)

We are using quite a few stm32 MCUs from 401 to 439, and our program becomes more and more complicated. In order to avoid possible deadloop, we have used watchdog to rescue the system, basically it is working well now. For quality improvement consideration, we want to know more about where watchdog reset occurs. And I've collected following… (Show more)
