Posted on January 25, 2015 at 21:06Hi,I have been tracking down a bug in my application that only appeared with certain optimisation options with gcc 4.9.3.It turns out the problem is that in the STM32F0 drivers the ''State'' member of the SPI_Handl...
Posted on March 13, 2015 at 17:00I have a board based on the STM32F107 where the VBUS pin is unused, and USART1 TX is used on PA9. This has worked fine for me up until now, as I used a pin previously to define whether the CI should respond to USB or...
Posted on August 06, 2013 at 15:30I am having trouble using the DMA transfer complete interrupt with the USB Virtual COM Port. The USB port stops functioning when the interrupt is called. The interrupt command is: DMA_ITConfig(DMA1_Stream7, DMA_IT_T...
Posted on February 20, 2015 at 10:59hi, I have downloaded the last stm32cube software including BSP for STM32discovery boards. I had issue with LSM303 accelerometer before i discovered that: in Drivers/BSP/Components/lsm303dlhc.c line 124 should...
Posted on March 11, 2015 at 20:26First my planI am using the STM32F411, and I am designing a custom boot loader specific to my application. This boot loader will first of all scan the internal flash memory beginning at address 0x0800C000 for 256 by...
Posted on February 22, 2012 at 08:12Hi, just unboxed my new STM32F4-Discovery board. LEDs shine and blink brilliantly, but where to find a suitable USB driver for my old and faithful WinXP laptop? Letting the PC find the driver did not result in an...
Posted on June 21, 2013 at 10:50Dear all, I am using the ''STM32_USB-Host-Device_Lib_V2.1.0'', which I think is the only one that fully supports the STM32f105/107 OTG functionality and has a Custom HID demo project, to add USB functionality on my de...
Posted on March 11, 2015 at 17:36I'm using stm32f4 Discovery board and planning to interface SD card via SPI , to achieve maxmimum throughput It'd be better to use DMA for block read/write. Does ST provide any samples of FAT-FS implementation for ST...
Posted on March 12, 2015 at 13:15I'm using a ST32F429IG in a project in which I implement a mass storage in an external serial flash memory chip. The data transmission is made via the HAL_SPI_TransmitReceive() funtion, so no interrupt or dma transfe...
Posted on March 12, 2015 at 15:05Hi, I am new to smt32 and also this kind of C programming. I tryied to understand the USB example for VCP offered by stm32 but without success. What I am looking for is to understand how I can send and receive messag...
