Posted on May 13, 2015 at 10:45 Hi All, I've been working my way through all the retarget.c threads on here and Keil.com today, trying to resolve the old Symbol __stdout multiply defined (by stdio_streams.o and retarget.o) Symbol __stdin multiply de...
Posted on May 13, 2015 at 16:36Hi I connected audio to ADC and can DSP with success only if the audio is from speaker out. I need to connect audio from a device which outputs 500mvpp. I am using the follow input circuit http://www.frinos.com/adc.png...
Posted on May 04, 2015 at 21:45 Hi folks, I'm trying to figure out how to resolve this w/out having to abandon DMA. Any suggestions are most appreciated. The problem seems to be provoked by a slightly larger write to the UART (which is...

Posted on May 11, 2015 at 18:37 Good afternoon, I am trying to port an application I wrote for the STM32F407 Discovery board, which makes use of the ADC, DMA and NVIC to the STM32F429 Discovery board. I receive a lot of errors wh...
Posted on May 12, 2015 at 17:21 After searching for a long time I understood that the only reading materials I can get are the reference manual and the ST library comments - not a lot. I imagine this is the main reason I can't get even simple th...
Posted on May 12, 2015 at 20:23Hello,I wrote a small and very short DMA2D example to resize a bitmap using bilinear interpolation. The resize process is entirely handled using the DMA2D Blender with a low CPU resource usage.The CPU, after a fast ini...
Posted on February 24, 2012 at 12:36Hi all, I'm searching to get work my UART4 port on my Discovery. I used the USART HyperTerminal_Interrupt example on stdPerif_example and I adapted to DISCOVERY. I see by some LedOn on the program that UART is wor...
