Posted on January 27, 2013 at 23:03Hi!I'm trying to make forward/inverse FFT. The target is to compare, that data before, and after FFT/IFFT are equal.// Vars definitionq15_t ADC_input[512];q15_t RFFT_output[1024];arm_rfft_instance_q15 S;arm_cfft_ra...
Posted on January 24, 2013 at 16:59hiI am using STM32W108CB and made my own pcb. I've stlink v2 and want to use it as Serial Wire Debugger.When I press 'connect to the target' in stlink utility I get message 'Internal command error'.I've tried to se...
Posted on January 27, 2013 at 15:58 Hi, I am trying to play some audio on my evaluation board,but no luck : I have a buffer that contain slices from various wav files,the buffer located in the external RAM ( if it matters) , and i tr...
Posted on September 23, 2012 at 07:38I have stmf4discovery board with an LCD screen connected via FCMC. I've taken the ADC3_DMA StdPeriph example and adopted it to use PC1 pin since my board does not have PF7 (I hope it does not). So, if I apply 3v ...
Posted on January 26, 2013 at 20:30Hello to all, I have a design where cpu has to transfer blocks of data to a uSD card working in SPI2 mode. My routine is : static void SPIblockTxDMA(uint8_t *SD_Buffer_Tx,uint16_t Len) { SPI_Cmd(SPI_SDMEM, DISABL...
Posted on January 11, 2013 at 10:40I tried to revive an older thread, but that seems not possible if it dates back before the last database meltdown ... Is there any simulation of STM32 MCUs available, specifically the F0 and F1 ? And I don't mean t...
