Posted on September 26, 2014 at 11:18 Hi Guys, Im currently try to implement a USB. The programm is derived from the CDC example. It is already working with 3 enpoint like in the CDC example. But I want only to work with 2 endpoint bu...
Posted on September 30, 2014 at 06:34Hello Pro, I want to save my data in to backup domain to backup data when reset happen ( watch dog timer reset). This is my code : uint16_t domua;// I wan to save this data. /* Configure the PVD Level to 2.9V */...
Posted on May 10, 2013 at 14:35Hi, There is a STM32F303 pin for VREF+ of DAC and ADC (in common). I would have suspected that this reference voltage input does adjust the conversion function in such a way that Vout max of DAC (i. e. digital FFFhex) ...
Posted on September 06, 2014 at 22:31 Looks like a bug has crept into the v1.1.1 Standard Peripheral Library -- if it's built with STM32F30X #defined (e.g. by specifying -DSTM32F30X on the gcc command line), the build will fail. Addition...
Posted on May 19, 2014 at 15:36Hi all,I've a problem with my STM32F103. I need to use fat filesystem on SD card to read/write/create files.I've connected the SD card to the SDIO interface and 4 wires mode with 47Kohm pull-up on cmd and data pins.I t...
Posted on October 01, 2014 at 09:51How can I generate two signals with a specific overlap time between them?I mean first signal to be square wave 50% duty cycle and the second one square wave inverse of the first one but with overlap time, that is ...

Posted on September 30, 2014 at 15:27 Hello, I've been trying to get any life out of the I2S3 output from my STM32 Discovery board, but for some reason I cannot even get a clock signal (CK), as seen with oscilloscope. It also never seems...
Posted on May 20, 2012 at 20:02 The input to this function is a 'Desired Frequency' and the function, fairly quickly locates (out of the 4 billion possibilities! (ARR(16bit)*PSC(16bit)) the correct values for a given TIMER'S PRESCALER(PSC) and P...
