Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Posted on October 23, 2017 at 14:33Hi, I am working with 'STM32F746G DISC' board, In USB_CDC using USB_HS mode, I wanted to Receive the data from PC-Terminal and same has to be transmitted back (echo type), which API's will be needed to develop this...
Posted on October 19, 2017 at 20:38 Hi all, I'm dealing with an I2C memory connected to a STM32F401 MCU and I'd like to check at runtime if the device is ready (or if something is wrong, e.g. with wirings). I'm trying to use the HAL_I2C_I...
Posted on June 11, 2013 at 12:05Hi, I have downloaded Dfuse and using the external Boot pins i jumped into the bootloader area(system memory), but dfuse is not detecting my device..when i connect the USB it shows as unknown device at the device ...
Posted on October 20, 2017 at 05:24We heard that most USB hardware has some limitations so that it can't reach the theoretical transfer speed, but we can't find the relevant information on the manuals from ST.We are considering using STM32F042K4 to ...
Posted on September 29, 2017 at 01:24About 6 months ago, I wrote a serial GUI under Windows to upgrade firmware on an STM32L052 via the UART2 port, where the firmware does a JumpToBootloader() to get things started. This took a lot of work and trou...
Posted on October 19, 2017 at 20:45Edit: It seems like the real question I need to ask is 'what is the definition of a bank area?'. After reading RM0394 Section 3.5.3, I rule out my previous assumption of an area being a further division. My current...
Posted on October 18, 2017 at 23:10So I am trying to write firmware for an STM32F0303, and I am trying to use USBD_LL_Transmit from the STM32Cube USB device library to send data to the usb host. The only documentation on this function that I can fi...
Posted on March 08, 2017 at 15:45I am working with the STM32F427 and HAL V1.6.0 and use the function HAL_I2C_Master_Receive_DMA.Sometimes (~20 times a day) I have troubles because after the callback HAL_I2C_MasterRxCpltCallback another byte is trans...
Posted on October 18, 2017 at 09:29Good morning,I'm working with STM32L475 MCU. I have no problems in programming it via SW interface, but I'm facing some problems when trying to program it via USB port (using Dfuse demo program by ST).First, I use ...
