Posted on November 02, 2015 at 00:43Hi,I'm using FLASH to store some data. Everything works great when I write in an empty address. When I try to write in a already used memory position, the stored value becomes to zero!I tried erase the sector befo...
Posted on October 29, 2015 at 23:45 I'm currently experimenting with writing a driver for USART1 at the register level for the STM32F4 Discovery board. I've followed the initialization procedure on page 963 of RM0090; however, when I connect to ...
Posted on November 02, 2015 at 19:21In my design the STM32F107 is connected to the MICRELL KSZ8081RNG ETH PHY (which operates in RMII v1.2 mode).Using the LwIP i can transmit ETH packets to the network but cannot receive any data from the net.Can t...

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...
