Does anyone know of a simple SD Card to internal DAC wav player, preferably STM32F100?

I have tried a lot of projects posted on the internet and the examples in the Discovery kits, but nothing but problems. My tools are STMCube or IAR. I have a customer who is late in delivering, so I am scrambling to help. Thanks much! Leigh

On the F100 you'd presumably need to use the SPI SD Card code for the Adafruit shield, along with FatFs, as a starting point.

STM32Cube_FW_F1_V1.8.0\Drivers\BSP\Adafruit_Shield\stm32_adafruit_sd.c

Not sure there is a prepackaged solution, the F1 is an old platform the ADC/DAC stuff I did used the SPL

Thanks much! Everything helps...

This was a test I did some weeks ago.

It uses USB OTG and a F4 series but ​the code should work easily in the F1 too.

Thanks much! Support just answered as well with some insights as to why the other projects I tried won't build. Once I have a full solution, I will post it.
