To use the PIC32MX795 in your project, include the files ETHPIC32IntMac.c and ETHPIC32ExtPhy.c in your project. You’ll also have to add a specific PHY implementation file (by default ETHPIC32ExtPhyDP83848.c is provided) depending on your actual external PHY selection.
Update the following definitions in HardwareProfile.h:
|
Macro |
Purpose |
Sample Value |
|
PHY_RMII |
Define this macro if the external PHY runs in RMII mode. Comment it out if you’re using an MII PHY. |
- |
|
PHY_CONFIG_ALTERNATE |
Define this symbol if the PIC32MX7XX uses the alternate configuration pins to connect to the PHY. Comment it out for the default configuration pins. |
- |
|
PHY_ADDRESS |
Update with the MIIM address of the external PHY you are using (the address on which the PHY responds to MIIM transactions. See the PHY datasheet). |
0x1 |
Update the following definitions in TCPIPConfig.h:
|
Macro |
Purpose |
Sample Value |
|
ETH_CFG_LINK |
Set to 0 to use the default connection characteristics (depends on the selected PHY). Set to 1 to configure the Ethernet link to the following specific parameters. Auto-negotiation will always be enabled if supported by the PHY. |
0 |
|
ETH_CFG_AUTO |
Set to 1 to use auto negotiation. Strongly recommended. |
1 |
|
ETH_CFG_10 |
Use/advertise 10 Mbps capability. |
1 |
|
ETH_CFG_100 |
Use/advertise 100 Mbps capability. |
1 |
|
ETH_CFG_HDUPLEX |
Use/advertise half duplex capability. |
1 |
|
ETH_CFG_FDUPLEX |
Use/advertise full duplex capability. |
1 |
|
ETH_CFG_AUTO_MDIX |
Use/advertise auto MDIX capability (effective only when ETH_CFG_AUTO is enabled). |
1 |
|
ETH_CFG_SWAP_MDIX |
Use swapped MDIX if defined. Otherwise, use normal MDIX. |
