Posted on June 18, 2015 at 15:25I have the STM32F105 RTC alarm working correctly internal to the chip, but I cannot get the alarm to control pin PC13.I have the BKP register configured to set the alarm output BKP_RTCOutputConfig(BKP_RTCOutput...
Posted on June 19, 2015 at 15:18I am using F429 in my project. The USB FS is required 168Mhz clocking, but the I2C need 180MHz in order to use 400khz speed. When I set the clocking to 168MHz and set the I2C speed to 100khz, the I2C always stop after...
Posted on June 19, 2015 at 01:48I'm working with a device that uses the SMB Address Resolution Protocol as part of the response to generating an internal alert. I have no difficulty reading and writing address registers in general (With the peripher...
Posted on May 11, 2015 at 05:18Dear sir: I use STM32F407 discovery board's ST-link feature to communicate with my custom STM32F427 board. I can download (and reset/run) the execution file created by uVision 5.0.5 via ST-link utility tool. However uV...
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...
