Memory space and key info
1.The sock.allowedinterfaces property refers to the Ethernet interface as "NET", Wi-Fi — as "WLN", 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 and installed Tibbits dictate which GPIO lines must be used as inputs and which — as outputs.
3.Default CTS/RTS mapping is different for each serial port:
4.Although the platform itself supports remapping, actual "wires" connecting the system to the GA1000 are fixed and your mapping should reflect this:
Supported Objects, variable types, and functions
•Sock — socket communications (up to 16 UDP, TCP, and HTTP sessions);
•Net — controls the Ethernet interface;
•Ser — in charge of serial ports (UART, Wiegand, and clock/data modes);
•Ssi — implements up to four serial synchronous interface (SSI) channels, supports SPI, I2C, clock/data, etc.;
•Io — handles I/O lines, ports, and interrupts;
•Lcd* — controls graphical display panels (several types supported);
•Kp** — scans keypads of matrix and "binary" types;
•Rtc — keeps track of date and time;
•Fd — manages flash memory file system and direct sector access;
•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.);
•Pat — "plays" patterns on up to five LED pairs;
•Beep — generates buzzer patterns using the onboard buzzer;
•Sys — in charge of general device functionality.
* The LCD must be connected to the TPP3 board externally, via Tibbits (Tibbit sockets).
** The keypad must be connected to the TPP3 board externally, via Tibbits (Tibbit sockets).
*** This may be an external modem connected to the TPP3 board or a GPRS Tibbit module plugged into the board.
