Introduction the steval-usbc2dp adapter is a miniaturized solution with a usb type-c plug and a displayport receptacle that implements the displayport alternate mode of the usb type-c and power delivery specifications for compatibility with the vesa ® standard. The adapter allows you to extend the s...
1 steval-usbc2dp system architecture the steval-usbc2dp is a full reference design that implements displayport alternate mode over the usb type-c and power delivery protocol. It is a highly compact solution with a usb type-c plug and a displayport receptacle on the same board, without any usb type-c...
1.1 usb type-c to displayport reference design architecture the steval-usbc2dp reference design for the usb type-c to vesa displayport adapter is a complete solution based on the following logical blocks: 1. A usb type-c reversible connector 2. A displayport connector 3. An stm32f072 mcu running the...

2 system setup the steval-usbc2dp dongle is a compact turn-key solution that demonstrates the versatility and convenience of the usb type-c port for displayport alternate mode. The plug and play feature of the usb type-c and power delivery specifications allows the adapter to operate immediately. 2....
Specific blinking sequences on the blue led d13 indicate the different stages in the displayport alternate mode procedure: 1. If the dongle is attached to a usb type-c only port (without power delivery negotiation capability), the led remains off. 2. When the dongle is connected to a usb type-c port...
