Posted on March 14, 2015 at 02:59i require to open multiple files simultaneously and, read and write multiple files using stm32f4 and fatFs , as a test i used f_open with 4 different file names and file pointers but only two files got created in car...
Posted on March 12, 2015 at 09:36Hi,in my application, I need to make signal filtering using digital filters.I take ARM's DSP library and fir example, but it is not so useful for me, because there are samples stored in memory already and they are us...
Posted on March 13, 2015 at 19:06Hello all, I faced problems with SPI2. First I interfaced a graphic LCD on SPI bus and could not get to working properly, though it works well on an Atmel 8 bit controller. Spent more than 3 weeks without much luck. ...
Posted on March 14, 2015 at 02:56I've used CubeMX to build a UV5 project that includes USB and CDC Device Class. Right out of the box the project compiles with no problem and runs. It enumerates as a Comm port.Now all I need are a few simple functio...

Posted on November 09, 2014 at 23:37I want to use DMA with double buffer. STM32CubeMX provides options for normal and circular buffer. Should I select circular buffer and then modify the source or is it better to wait for the next version of STM32Cu...
Posted on March 11, 2015 at 09:04 I am using microcontroller STM32F On reading EEPROM operation with I2C microcontroller gives 7 clock pulses instead required 9. There is fragment of transmitting on picture. When this cause o...
Posted on August 21, 2013 at 17:05Hello. I have been searching the forums and cannot find an answer, hence I am starting a discussion here. I have been using the STM3220G-EVAL board and the HS USB onboard PHY (obsolete NXP device). I have since crea...
Posted on March 13, 2015 at 16:17Hello, I'm running an STM32L151 at 32MHz and SPI BaudRate = fPCLK / 4. The device is an SPI Master, and tries to read a Slave as fast as possible. I'm using DMA TX and RX to speed up things. I can see the SPI clock r...
Posted on October 04, 2013 at 17:53Hi All, i'm using STM32F407 in USB CDC mode, i'm having issue when i'm sending bytes from STM to PC, client application on PC is minicom, issue is when i close minicom and STM runs into ''frozen'' state until i...
