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 26, 2013 at 22:45Hi, I'm currious if it is possible to share data between two STM32 devices, using the FSMC interface. Is it possible to configure one device as a Master and the other as a slave and use the FSMC? I would make the s...
Posted on January 26, 2013 at 22:36Is there a place that one can get the pinout tables for the STM32 family devices in a format other than PDF? The tables in the PDF datasheets and reference manuals are not easily copied to other software, and it s...
Posted on January 28, 2013 at 09:16Hello everyone.I need to connect, programm and debug project on one board with 10 pin swd.1. vcc +3 V2. tms_swdio (pulled up to +3V throught 5.1 kOhm resistor)3. gnd4. tck_swclk (pulled up to +3V throught 5.1 kO...
Posted on January 11, 2013 at 11:12Here is a STM32F103-question.TIM2 is using TIM_OCMode_PWM1 and TIM_OPMode_Single (one-pulse mode).Im using TIM2 CH1 for (internal) triggering ADC injected reads using a compare. Im using TIM2 CH2 for (internal) tri...
Posted on May 30, 2012 at 01:55I am new in developing firmware by using STM32L152VBT6. I need to configure DMA to transfer data from SRAM to SD Card. The data would be {1, 2, 3, 4, 5, 6, 7, 8, 9, 0}. However, I could not write into SD Card and I cou...
Posted on January 27, 2013 at 23:13Hi!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...
