| 5 | This capture is taken from the libopencm3 example for a USB HID device on the | |
| fc997d14 | 6 | Paparazzi Lisa/M board. In this applicaton an SPI accellerometer is read and |

| 32 | -p 1=USB_DM,2=USB_DP,3=SPI_NCS,4=SPI_SCK,5=SPI_MOSI,6=SPI_MISO \ | |

| 35 | The OLS can't actually capture 50ms, so it just captures as much as it can | |
| fc997d14 | 36 | buffer. No triggering was used. |
