Posted on May 28, 2015 at 20:37Hi, I'm using an audiocodec conected to I2S2 of the uC. Tx on I2S2_SD and Rx on I2S2_extSD. I can send audio to the codec as a master and codec play the audio Ok. I'm using DMA and on DMA_Tx_Cplt IRQ I configure the ne...
Posted on May 28, 2015 at 18:53Hi,I just got my new STM32F4 discovery board, i wrote a LED test program with CoIDE and flashed it, but LED didn't toggle, even i try to press RESET button. Then i go to debug mode and click run, it starts to toggle. I...

Posted on July 19, 2011 at 17:47Hi, I am trying to produce PWM signal by using TIM17 channel1 on PORTB-9, but i can't get the PWM signal. In debug mode i can see that TIM17 COUNTER register advanced and do overloop, but i just cant see the PWM signa...
Posted on May 25, 2015 at 08:16I am using stm32f4 discovery board. from ADC I take 1ksample/sec and accumulate it. after accumulation of 30Ksamples, process it through band pass filter. output of band pass filter is very large +ve and -ve values ex...
Posted on May 28, 2015 at 10:37In a few days I will start the first project with STM32 on a dedicated hardware. I would like to ask some suggestions about debugging: 1) JTAG or SWD? So far I used JTAG on AVR core and it worked fine. I don't know SWD...
Posted on May 26, 2015 at 14:44We have a solution, which reading audio file from SDCard and playing by I2S. It works ok when the CPU Clock Speed is >= 84Mhz. To reducing the Power Consumption, we have to reducing the CPU Clock Speed to 24MHz, then t...
Posted on May 26, 2015 at 21:23Hi, all. I have an STM32F401Discovery Kit using an STM32F401VCT6. I have wired an external SD card connector and have successfully implemented Elm-Chan's FATFs using the SDIO SD card interface. All works well, I can mo...
Posted on May 23, 2015 at 11:34I have a board with a 32 bit SRAM and have used CubeMX to configure a 32 bit data bus, a 10 bit Address bus with a Chip select of NE1. Briefly, Cube has produced the MX_FMC_Init(); file with settings as follows:- hsram...
