Posted on April 01, 2015 at 19:41Hello, I'm implementing my own boot loader code for stm32f4. In this boot loader I want to implement a hid class updater (for device firmware) which accept DFU class specific requests. On the PC side I want to modify...

Posted on March 30, 2015 at 16:20Hi, we're using STM32F407VG on our project. When we reset the circuit for BOOT, microcontroller is setting B13 pin (which is not using as boot pins) . How can we stop this situation? Can we make any difference for th...
Posted on March 25, 2015 at 12:08I am experimenting STM32 by using a STM32F429I discovery board, with a MEMS on board. At the moment, any attempt to read the MEMS via SPI by using the Cube libraries has failed. On the other hand, another example pro...
Posted on March 16, 2015 at 02:32Hello everybody,I'm new with USB devices and I want to develope a Virtual Com Port with STM32L151. I get a example named VirtualComport_loopback for IAR in the packet STM32_USB-FS-Device_Lib_V4.0.0.I have some questi...
Posted on March 30, 2015 at 11:32It appears that DFU in the STM32F42x ROM Bootloader has an issue: The device returns a descriptor response string as a malformed packet (according to wireshark) for the @Internal Flash interface. The bLength field in...

Posted on March 29, 2015 at 00:45Hi, I am a student studying EE, and do not have any experience in circuit design besides the theory being taught in college and a six month hardware design Co-Op. Currently, I am developing a board to be used for...
Posted on March 29, 2015 at 00:15 Hi, I am trying to send about 2500 bytes over UART from my computer to my STM F091 board. When I try to send small chunks, upto say 100 bytes, the data seems fine. About 1-2% of the bytes i read back are corrupt...
Posted on March 27, 2015 at 12:22I need to integrate an old code written using the Standard Peripheral Library to a new (big)project that's using CubeF4.As easy as it sounds I can't find any commonality between the libs..1. Is there any documentatio...
