Posted on November 15, 2015 at 22:14I want to develop a JTAG interface using STM32F103. One way is to use GPIO to drive/read the signals, another way is to use SPI, but unfortunately TMS signal is not present. Is there a way to use SPI and simulate ...
Posted on November 04, 2015 at 12:51I recently bought a STM32F4 discovery and I'm interested in audio processing. I started trying to record some audio data using the MP45DT02 and the I2S module.The program is based on the play and record demo, it r...
Posted on November 14, 2015 at 20:37Hello Is there any document from ST out there which actually explains how fast and slow ADC channels in some devices (e.g. the stm32l4 has them) differ? The only real information the datasheets hold is the absolut...
Posted on November 11, 2015 at 12:20 Hello ; I have a problem for the last few days it made be puzzled hope you could help me please . I am using keil compiler with STM32f334c8 ; I had a project based on stm32f429 using FFT from ARM DSP...
Posted on November 14, 2015 at 12:13Hi, I have an hardware with a stm32F7xx and an FTDI chip (4232) that controls the JTAG. I would like to program the flash of the stm32F7xx via openocd (this procedure is really straightforward for the previous stm...
Posted on November 12, 2015 at 20:21 I am generating music using STM32L152RC. I have DAC configured the same for both channels DAC_OUT1/2 using PA4/PA5. RCC->APB1ENR |= RCC_APB1ENR_DACEN; // Enable DAC RCC->AHBENR |= RCC_AHBENR_GPIOA...
Posted on November 13, 2015 at 11:01 Hi guys i am struggling to convert 2 8bit values into 16bit value, please help me //Global variable volatile uint8_t data[16]; volatile uint16_t BIG; main() { data[1] = 23;//msb data[0] = 21; //lsb BIG...
Posted on November 13, 2015 at 17:04I'm developing an application that requires me to quickly and constantly reading 5 ADC channels.I'm using the STM32F030F4P6. I set it up to do a continuous conversion and told it the 5 ADC channels I need. I have ...
Posted on July 03, 2014 at 10:34 Hi, I am trying to let my STM32F429 Disco Board sample in triple mode interleaved. I mainly copied the code from ST, with small changes, and it also works. But the word-array I want the DMA to transfer th...
Posted on April 24, 2013 at 11:19Hi,I'm looking to sample a signal (well, 2 actually - quadrature analog signals) at a fixed sample rate, but I'm baffled by the lack of any example in the Standard Peripheral Library on how to achieve this.I would ha...
