/* DMA Stall | |
This sketch will demonstrate how the FreeTrouch library code makes reads to | |
PTC peripheral registers without the required Read-Synchronization. While | |
such reads succeed, they stall the AHB-APB Bridge C. | |
This is normally not an issue - but if there are other accesses going through | |
that bridge, then they will be stalled as well. A common example is to use the | |
DMAC to transfer data to the DAC or from the ADC. These peripherals are on | |
the same bridge (C). Stalls caused by non-scyhcronized reading seem to be on |

These are instructions for building a stand alone, headless, music computer based on the Pisound audio card and a RaspberryPi 3.
I use this set up in my live performance rig where it does all of the following without breaking a sweat:
