Posted on January 09, 2013 at 10:56Good morning, i'm using a STM32F0discovery board, i'm developing an application that read and write informations on UART2 port, i'm using only TX and RX pins (PA2 and PA3).Well, at this time my application ask me w...
Posted on January 08, 2013 at 14:42 I have tried a STM Studio, yersteady downloaded. For sample rates less than 100ms are not shown all steps. Is it possible to show steps smaller than 100ms, how and how small they can be? I use an example deliv...
Posted on January 09, 2013 at 13:01I am trying to falsh a example program through a STM32 discovery debugger/programmer on an external STM32 chip. all the connections are right and done according to the instructions written in the Datasheet of STM d...

Posted on January 09, 2013 at 02:49from ST documents PDF (LED light control using DMX512 control method ), it mention the application source (IDE IAR Embedded Workbench) is available only on request and is covered by license agreement. So, Can someo...
Posted on January 08, 2013 at 03:18I am trying to get the F4 discovery board to communicate with a FPGA board via the FSMC but I am having some problems. I have connected the data 0-15 lines, we, oe, and addr 16-23 from the discovery to my fpga. I c...
Posted on January 08, 2013 at 20:31I have a question. I need to connect 2 to 6 STM32s together. I have motors I need to collectively control with a human machine interface. Each motor will be controlled by one STM32. The HMI also needs a STM32. ...
