Posted on June 21, 2013 at 10:14Hallo all,How do I program the NOR Flash on the STM3210E-Eval board from my IAR platform? I'm experimenting with the STM3210E-EVAL demonstration firmware (UM0549) and accidentally deleted the contents of the NOR Flash...
Posted on June 27, 2013 at 00:37Hello, the I2S interface is specified up to 192kHz, and actually the stm32f4xx_spi.h file has defines from 8kHz up to 192kHz. I am wondering if anybody has ever tried to push the I2S interface up to 384kHz (and po...
Posted on June 25, 2013 at 14:40 Hi, I try to implement a IIR filter with the '' arm_biquad_cascade_df2T_f32'' function from the CMIS dsp libraries and I encountered a problem: my output datas and my pstate table are overflowed after ...
Posted on January 12, 2012 at 21:59Hello everybody! In my program I have to start two timers exactly at the same time. In my current code I start them behind one another (just one line of code each) but unfortunately the error with this method is to...
