PD Builder¶
The PD Builder feature allows the user to modify all Power Data Objects (PDO) presented by the USBHub3c. This includes both sourcing and sinking PDOs of the USBHub3c.
Use Cases
Designing PDOs for you own device
Exposing DUTs to PDOs
Restricting DUTs from PDOs

HubTool¶
HubTool allows the user to visually build a PDO without needing to know anything about the Power Delivery specification. Once created you can immediately apply it to the USBHub3c.
Example¶
static const int TEST_PORT = 1;
static const uint32_t MY_CUSTOM_SOURCE_PDO = 0x0001912C;
static const uint32_t MY_CUSTOM_SINK_PDO = 0x0002D12C;
aUSBHub3c stem;
stem.discoverAndConnect(USB);
//Change local SOURCE PDO 1 to MY_CUSTOM_SOURCE_PDO
stem.pd[TEST_PORT].setPowerDataObject(powerdeliveryPowerRoleSource, 1, MY_CUSTOM_SOURCE_PDO)
//Change local SINK PDO 1 to MY_CUSTOM_SINK_PDO
stem.pd[TEST_PORT].setPowerDataObject(powerdeliveryPowerRoleSink, 1, MY_CUSTOM_SINK_PDO)
//Do Stuff
stem.disconnect()
TEST_PORT = 1;
MY_CUSTOM_SOURCE_PDO = 0x0001912C;
MY_CUSTOM_SINK_PDO = 0x0002D12C;
stem = brainstem.stem.USBHub3c()
stem.discoverAndConnect(brainstem.link.Spec.USB)
#Change local SOURCE PDO 1 to MY_CUSTOM_SOURCE_PDO
stem.pd[TEST_PORT].setPowerDataObject(powerdeliveryPowerRoleSource, 1, MY_CUSTOM_SOURCE_PDO)
#Change local SINK PDO 1 to MY_CUSTOM_SINK_PDO
stem.pd[TEST_PORT].setPowerDataObject(powerdeliveryPowerRoleSink, 1, MY_CUSTOM_SINK_PDO)
#Do Stuff
stem.disconnect()
