Posted on October 08, 2014 at 03:24Hi,Iam trying to use DSP lib on STM32F4 chip. I run the example project of FFT on CMSIS lib and it's ok:an float array ==> FFT ==> result   it's ok.But I try on my board:Signal generator => external ADC => FFT on S...

Posted on September 19, 2014 at 03:46Hi,I working with STM32F103 chip and trying to test SPI2. I use the example from: STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\SPI\SPI_FLASHBut replace#define sFLASH_SPI                    ...

Posted on September 08, 2014 at 05:01Hi,My project with STM32F407 requires save an 100 element array into internal flash(do not use backup SRAM). But first, I have to erase the location sector (128KB), and it take to much time  (about 800ms). Someon...

Posted on June 18, 2014 at 12:07Hi all,I develop the SPEEX encoding on STM32F4 follow the application note : ''Vocoder demonstration using a Speex audio codecon STM32F101xx and STM32F103xx microcontrollers'' and it's ok. I can play realtime with Spe...

Posted on March 17, 2014 at 04:52Hi,I trying to use ST-LINK/V2 in STM32F4 discovery board to program an external application in SWD mode.I connected Pin GND, Pin 3.3V, Pin SWCLK, Pin SWDIO from external board to ST-LINK/V2 and remove connection from...
