| | 237 | === TPS2582x CC controller |
| | 238 | [=#tps2582x] |
| | 239 | The TPS25821 CC controller used on the above Venice Type-C connectors presents the port as a Downstream Facing port (host/power). However the following options exist for using this as a Upstream Facing port (device): |
| | 240 | - a Type-C connected device a Type-C to Type-A plug (device) cable can be used for device-mode to a Type-A host device (Note that a Type-C to Type-A socket (host) cable can still be used for host) |
| | 241 | - a build option exists to remove the Type-C CC Controller and load 5.11kohm Rp resistors on the CC lines such that the board will behave as an Upstream Facing Port (UFP) sink/device to a connected Type-C device |
| | 242 | - some devices may allow forcing their Type-C connector host to host mode via software |
| | 243 | |
| | 244 | |
| | 245 | == USB Type-C |
| | 246 | USB-C or USB Type-C is a 24pin reversible connector that supersedes previous USB connectors which has become a very popular connector in modern devices. Because the connector can carry multiple types of data as well as provide and sink power, it is worth detailing the capabilities of the various Type-C connectors offered on Gateworks Single Board Computers. |
| | 247 | |
| | 248 | Several Gateworks boards have USB Type-C connectors on them: |
| | 249 | || Board || Connector || Supported || CC Controller || VBUS || Notes || |
| | 250 | || GW82xx || J28 || USB2.0 / USB3.0 || TPS25821 UFP || 5V@1.5A || ^^^1,2^^^ || |
| | 251 | || GW75xx || J14 || USB2.0 / USB3.0 || TPS25821 UFP || 5V@1.5A || ^^^1,2^^^ || |
| | 252 | || || J1 || USB2.0 / USB3.0 || TPS25821 DFP || || ^^^1,2^^^ || |
| | 253 | || GW74xx || J3 || USB2.0 / USB3.0 || TPS25821 DFP || 5V@1.5A || ^^^1,2^^^ || |
| | 254 | || GW71xx || J2 || USB2.0 || TPS25821 DFP || 5V@1.5A || ^^^1,2^^^ || |
| | 255 | 1. While the CC controller presents the port as a Downstream Facing host/power port to a Type-C connected device a Type-C to Type-A plug (device) cable can be used for device-mode to a Type-A host device or a Type-C to Type-A receptical (host) cable can be used for dual-role support ([#tps2582x see here regarding dual-role capability]) |
| | 256 | 2. A build option exists to remove the Type-C CC Controller and load 5.11kohm Rp resistors on the CC lines such that the board will behave as an Upstream Facing Port (UFP) sink/device to a connected Type-C device |
