Posted on July 17, 2014 at 14:50Hi, We are using ST-LINK/V2 to flash STM32F103XC, on our customised board. While flashing we get issue 'Failed To Read CPUID'. Attaching Snapshot for your kind reference. Waiting For Your Reply !!!!!!! Regards, Ajees...
Posted on July 17, 2014 at 02:32 I am using an STM3240G-EVAL board to read in values from the ADC. I print the values from the ADC to the LCD on my board using the print function below. I physically connected the temperature sensor to 3.3V, ADC3, a...
Posted on July 16, 2014 at 16:03Hi, I recently buy a STM32L152 Nucleo, I begin with mbed.org but I prefer to develop offline. So I was wondering if there are any plug-ins to debug my programs. I follow this tutorial : http://erika.tuxfamily.org/wi...
Posted on July 15, 2014 at 17:29Hey guysI'm working on a projet and i'm using STM32f4 discovery board.I wrote program to send data by USB (from MCU to PC by Bulk transfert) in full speed mode.Usually the throughput should be 12 Mbits/s but mine is o...
Posted on March 06, 2014 at 22:33Hullo guys , ....... I got SDIO and DMA working fine , but now i want to use the DMA so store the data automatically into external SRAM for further processing , now the problem is that the documentation tells very fe...
Posted on July 16, 2014 at 10:33 I am using a F401 to read 1024 Samples with 40ksps and it works fine so I hope that the code is ok. DMA_INIT.DMA_Channel = DMA_Channel_0; DMA_INIT.DMA_PeripheralBaseAddr = (uint32_t)ADC1_RDR; DMA_INIT.DMA_...
Posted on January 08, 2014 at 10:46Hi,I was working with my stm32f3discovery and using the On-board ST-LINK/V2 for debug/ flash programming.I was working fine: flash download, debug and so on.After that I've disconnected the board. When I've reconne...
Posted on July 16, 2014 at 02:29 Hi! I have a small rtos and I have to write a string every 5 ms to a sdcard. This (pseudo)Code works fine: void SDTask(...){ // some init for( ;; ){ SDopen(&File); SDWriteString(&File,SDstr...
Posted on July 14, 2014 at 15:38Hi,I am trying to do the FFT over an input real data (audio) on STM32F4 DISCO EVK & external CODEC. I have used the CMSIS function arm_rfft_fast_f32() http://www.keil.com/pack/doc/cmsis/DSP/html/group___fast.html I ...
