Posted on March 21, 2013 at 11:55Hi,I am trying to send Datas to a 24C128 EEPROM via I2C interface of an STM32F4 Discovery. The problem is that I am not receiving the same value I am writing into the EEPROM. I am trying to write 0x05 into 0x00 addre...
Posted on March 26, 2013 at 12:02Dear all, I have developed a board on which a STM32F205 microcontroller is connected to an asynchronous external SRAM (ISSI IS61WV102416BLL) which has read/write access times of 10ns. This RAM is used as a picture b...
Posted on March 27, 2013 at 08:55Hi all!I am currently working on a project where i am to program the MCU (STM32F107) over the CAN bus. I have looked into to the ''in-application programming'' and the bootloader datasheet, but there is some question...
Posted on March 22, 2013 at 21:09Hello,I have a problem which i cannot resolve.My first code, a DCF77 receiver which update my RTC once a day runs fine without any problems.Now, i have added a new function to calculate the Sunrise or Sunset time for...

Posted on March 01, 2012 at 14:49Hello, i have working code for SMT32F103 without fsmc controller, and now i was able to make code for STM32F4 with fsmc controller but it look like speed is the same. Where fsmc will give my speed improvement ? or i...
Posted on March 26, 2013 at 15:17Hi,USB Device VCP example using EWARM works well as debug build on my machine. I use Project -> Edit Configuration and make release build. When I try to download *.bin file I get error message: �Failed to generate .s...
Posted on March 25, 2013 at 17:36Hi, after I finally got my option byte programming running nicely (STM32F4). Just now I recognized that this collides with the WWDG being active (WWDG max time is 69msec, but option byte programming requires a 16kB e...
Posted on March 25, 2013 at 22:18Hi i would like to use the circuit MAX3232 (RS232 adapter) to connect two PORT RS232 with this circuit using just TX and RX onlyif possible this experience?????and thank you
Posted on March 26, 2013 at 00:18Hello, I have USB problem with my application with this uc. Your User manual UM0551 ''USBHID demonstrator'' would be useful and thanks to the ST support, I have received this project and soft to install in my PC. b...
