Posted on May 21, 2014 at 13:48HelloWe have made a custom board which uses a STM32F429II. On that board we also have a SDRAM memory chip of 512Kbit that is connected to the STM32 with the FMC peripheral.We confirmed that the memory chip is working c...
Posted on April 17, 2013 at 00:21 I'm using the STM32F4x7 + LwIP example code, modified to work with RMII and a LAN8720 PHY. I can send and receive Ethernet data - great! Unfortunately whenever I send a UDP packet, it has 50 bytes more pa...
Posted on May 20, 2014 at 13:39we've made an oscilloscope that displays data on PC screen with a software,which is creted on Qt Creator. The MCU software works well on STM32F4 Discovery board,which has STM32F407VG; but when we program STM32F405RG,pr...
