The STM32F100VB microcontroller features an embedded DAC which can be used to
generate output signals.
In this demonstration, any wave file stored under the USER folder in the MicroSD card can
be opened using the file system DOSFS and transfered to the internal SRAM by block (512
bytes) using the DMA and the SPI interface. Timer 6 (TIM6) triggers the DAC to generate
28/48
files) and displays only the .BMP files having the following format:
