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 January 15, 2012 at 01:50Hi: the USB functionality on the STM32 is great, but it is not really deployable for USB-serial given that the only Virtual COM (or Virtual TTY) driver is for Windows. For dev-kits, windows is OK. For actual prod...
Posted on February 14, 2012 at 13:26Hi all. I did some projects around the STM32F103 managed by a GUI on PC, via USB. Now I would like to address more than one devices (STM32F103) by the same PC and the same USB cable. So the problem is how to give ...
Posted on March 02, 2012 at 16:28 Hello! I have a board based on STM32F Ethernet PHY: KSZ8721BL; LwIp 1.3.2. I took [url = ''http://electronix.ru/redirect.php?http://www.st.com/internet/com/SOFTWARE_RESOURCES/SW_COMPONENT/FIRMWARE/st...
Posted on February 29, 2012 at 10:10Hello, I have a problem to communicate with a PHY when I use an external oscillator for the Ethernet part. If I use the clock generated by the microcontroller (MCO pin) there is no problem, the communication work ...
Posted on February 22, 2012 at 09:48Hi all, I have a problem with SDIO+USB Mass storage device. My eMMC driver now works (in stand alone without USB), and the USB mass storage device also works only if I remove the callbacks functions of init emmc, ...
Posted on February 16, 2012 at 15:27I'm wondering if it is safe to have a 5V power supply connected to the EXT_5V pin at the same time as the board is connected to the computer via USB (from which the board also derives a 5V supply). The Discovery u...

Posted on February 14, 2012 at 22:49Title says it all. I'm looking at purchasing a USB host stack, and one of the vendors mentioned that perhaps the F103 doesn't support Host mode. I'm just trying to do something simple: datalogging to a USB flash...
Posted on January 25, 2012 at 21:09Doesn't work. The assertions fail because the intterupt mode definitions of PHY_MICR and PHY_MISR aren't included in the macro ''IS_ETH_PHY_REG'' used for the asserts. I am not certain what other things aren't ha...
Posted on December 14, 2011 at 23:57Hi, I'm working on a project on a STM32F4 where I want to update firmware over a GPRS modem from a webserver. In the past I've taken the approach of having a 'fixed' bootloader section that was robust and solid......
