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 28, 2015 at 12:13Using STM32CubeMX to generate code for STM32F427ZITx processor. When changing the clock source from HSI to HSE the generated code updates the PLL fields but still maintains the source of the clock as HSI as shown below...
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...
Posted on May 28, 2015 at 07:23i brought STEVAL-IEG001V2 from mouser with bulk id Z4T21418E002. but as mentioned in user manual i did not received any Firmware (code for microcontroller). kindly provide any link for firmware. Thanks
