Posted on September 04, 2014 at 12:28Hello,I am a student that is designing a prototype with STM32F207VC. I'm trying to choose a 25 MHz crystal oscillator to have ethernet, with AN2876 guide. I see in this guide the recommend crystal STS25ASM , but ...
Posted on October 30, 2015 at 14:56Hi I am struggling to get the External Audio Clock Input (PC9 12.288MHZ) to be output by the SAI Master clock pin PF7. I have used STM32Cube to set it up and it all looks ok, but I can not get any output on the S...
Posted on October 24, 2015 at 22:52Hi Folks, am running The SD interface, along with FatFS on an F4 Discovery board plugged into a Discovery-BB which has a uSD card slot. I am running DMA for Rx and TX data, 4 bits wide to the card. It all runs gr...

Posted on October 28, 2015 at 14:07 Hi, Used the STemWin with quite a few demos on STM32F746G-Discovery so far succesfully, yet it seems that the GUI_CopyRect is not working. Tested it with many code variations but no rectangle n...
Posted on August 11, 2015 at 17:48Hi, I'm trying to see some lwip examples on the STM32F7 Discovery. On that board, only one lwip application/example exists whereas for the EVAL board there are quite a few there covering many aspects of TCP/UDP/HTTP...
Posted on October 11, 2015 at 14:47On the STM32F7-DISCO a signal from GPIO Port I13 LCD_INT connects to the 480 x 272 LCD.The STM32F745xx/STM32F746xx datasheet says that the AF14 mode of this pin is LCD_VSYNC. On the DISCO the LCD_VSYNC is on GPIO P...
