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...
Posted on September 30, 2014 at 21:29Hello,I've been racking my head trying to make sense of how to correctly configure the I2S Hardware to interface with the MP45DT02 microphone. I've been looking at ST's waverecorder.c for inspiration but I think ...
Posted on September 13, 2014 at 01:46I am having troubles setting up IAR Function Profiler so I wanted to double-check: The grey ''ST-LINK/V2'' device vs the debug interface within discovery board. Are these the same exact thing? At least my Windows...
Posted on September 17, 2014 at 09:35Hello. I am working in a R&D Project with the STM32 MCU. I have implemented Ethernet functionality like examples provided by ST. Frame transmission and reception are OK (checked with Wireshark). Now I must add PT...
