Posted on June 19, 2015 at 13:27Hello, what is a sensible relation between the GPIO speed setting and peripheral device speed? E.g. OSPEED = 00 on a >2.7 Volt STM32F42x with 10 pF load has a value of 8 MHz max. Is that good for a SPI clock rate of 8...
Posted on June 18, 2015 at 13:29Hello everybody,I use a SD card (SDIO). - When the SD card is inserted but not mounted, my analog inputs convert voltages with a very good precision.- When I mount the SD card, my analog inputs starts to convert volta...
Posted on June 15, 2015 at 10:20Hi,I noticed that when i'm trying to flash via the ST-Link_CLI in win 7 when i'm administrator.the response that i'm getting from the ST-Link_CLI is ''Unable to open file!''but when i'm doing it without setting my se...

Posted on June 18, 2015 at 22:06Hi, I have been trying to run critical interrupt routines from ccmram with gcc toolchain following the instructions in http://www.st.com/web/en/resource/technical/document/application_note/DM00083249.pdfI think I have...
Posted on June 18, 2015 at 16:54In one project there is a large rotating machine. It would help a lot if programs could be uploaded wirelessly(, while the motor is on). We would like to do other things, so doing our own solution is not good idea. It...
Posted on January 10, 2014 at 04:14Working on STM32F051. The bootloader works fine but the interrupt vectors in application file doesn't work even after locating vector table to SRAM. Any solution will be appreciated.
Posted on June 18, 2015 at 11:41Hello,I have written own bootloader/IAP that should start next firmware (jump to it).It is working very well, but when the firmware is loaded, then interrupts are not working.Of course I have configured:#define VECT_T...
Posted on June 15, 2015 at 10:05Hi, i want to use the STM32F042F in a TSSOP20 package. I need USB (device) and CAN. Both USB and CAN are routed to PA11/PA12. Datasheet tells, that PA11/PA12 can be remapped to PA9/PA10. Does the USB_DP and USB_DM sta...
Posted on June 18, 2015 at 14:51 I am working with the Discovery development board STM32F407 microcontroller and building using Eclipse/GNU. My project has a bootloader and an application and I would like to have a variable in RAM that both...
