Posted on March 15, 2015 at 20:57Could it be because max DMA transfer size is 64k elements ? (240x320 => 76800, truncated to 11264 on a 16bit register)
Posted on December 04, 2014 at 07:59Maybe I should have pointed you to http://jjmz.free.fr/?p=91 as it was the closest to the wav example. Then I progressively adapted the code to use ChibiOS functions instead of the SPL functions. Some maybe (and h...
Posted on December 03, 2014 at 14:17Yes it was compiled under Linux, with Gnu GCC Arm embedded ( https://launchpad.net/gcc-arm-embedded ). The basis was also the WAV example from the STM32F4 discovery platform.
Posted on December 03, 2014 at 08:24Hi, It seems that your code is trying to read from the file the same number of data that you output to the DAC, which is abviously wrong, since the MP3 data is compressed. Long time ago, I have used Libmad on the ...
Posted on October 30, 2014 at 17:06Well, your logic analyser acquisition was showing 16 bit transfers. Maybe you should also try to change the MISO GPIO configuration : it should be an input pin, and I am not sure the GPIO_PinAFConfig call is changi...
