STM42F407VG/MB997C I2S3 output silent
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...
Function to calc PSC and ARR for a desired frequency, fairly fast!
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...
I2S Interfacing with MP45DT02 PDM Mic on STM32F4 Discovery
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 ...
ST-LINK/V2 vs stm32f4discovery?
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...
PTP implementation in STM32F437ZGT6
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...

USB audio device reference / example code, for multiple sampling frequency
Posted on September 19, 2014 at 17:18I'm designing a USB microphone, using STM32F0. All of the reference or example codes I can find are for USB speaker, and further more, they support only single sampling frequency. Is there anybody can provide any...
