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 ...
Posted on July 12, 2014 at 11:17USART communication with stm32f4 discovery application did. At the beginning of the data sent to the PC comes an unwanted character. Sent from the computer to one of the characters I can not even. I changed it to HSE ...
Posted on July 15, 2014 at 14:51Hi I am using STM32F429 with IAR work environment and i am trying to sync two clocks first clock: MCO2 is configured to output 29.5MHZ by using PLLI2SCLK second clock: LCD-TFT configured to output 14.75MHZ (half of M...
Posted on July 15, 2014 at 22:16Hi, With the Keil qVision v5 Logic Analyzer I'm tracing (ST-Link) an single ADC value which is updated every 10 microsecond. Directly after starting the trace I get ''Trace: SW Buffer Overrun''. Is this a ST-Link lim...
Posted on July 15, 2014 at 17:21Hi,I am currently implementing a USART rx driver on an STM32F303xxx using a receive DMA buffer. The motivation to use DMA is to allow reception of bursty high speed (8Mbps) data. [note that using HW flow control doesn...
Posted on July 15, 2014 at 17:12I'm trying to understand how this function should be used on an F405 chip. The code that calls calloc is all generated from a simulink fuzzy controller model so I'm confident it's correct in terms of code.The program ...
