  1. The sock.allowedinterfaces property refers to the Ethernet interface as "NET", PPP — as "PPP", and PPPoE — as "PPPOE". Sock.targetinterface and sock.currentinterface properties rely on the pl_sock_interfaces enum, whose members differ depending on the platform.
  2. Surrounding board hardware dictates which GPIO lines must be used as inputs and which — as outputs.
  3. CTS is permanently mapped to 0- PL_INT_NUM_0 (0- PL_IO_NUM_0_INT0). RTS is permanently mapped to 2- PL_IO_NUM_2.

Supported Objects, variable types, and functions

  • Sock — socket communications (up to 16 UDP, TCP, and HTTP sessions);
  • Net — controls the Ethernet port;
  • Ser — in charge of the RS232 port;
  • Io — handles I/O lines, ports, and interrupts;
  • Stor — provides access to the EEPROM;
  • Romfile — facilitates access to resource files (fixed data);
  • Pppoe — provides access to the Internet over an ADSL modem;
  • Ppp — provides access to the Internet over a serial modem (GPRS, POTS, etc.);

This platform supports the standard set of variable types and functions (a.k.a. "syscalls") except aes128enc and aes128dec. These AES128 functions are not present on the DS1100 platform.
