Comments:

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:

 

RTS

CTS

Port 1

0- PL_IO_NUM_0

0- PL_INT_NUM_0 (16- PL_IO_NUM_16_INT0)

Port 2

1- PL_IO_NUM_1

1- PL_INT_NUM_1 (17- PL_IO_NUM_17_INT1)

Port 3

2- PL_IO_NUM_2

2- PL_INT_NUM_2 (18- PL_IO_NUM_18_INT2)

Port 4

3- PL_IO_NUM_3

3- PL_INT_NUM_3 (19- PL_IO_NUM_19_INT3)

 

4.Although the platform itself supports remapping, actual "wires" connecting the system to the GA1000 are fixed and your mapping should reflect this:

 

CS

PL_IO_NUM_49

CLK

PL_IO_NUM_53

DI

PL_IO_NUM_52

DO

PL_IO_NUM_50

RST

PL_IO_NUM_51

 

Supported Objects, variable types, and functions

Sock — socket communications (up to 16 UDP, TCP, and HTTP sessions);
Net — controls the Ethernet interface;
Wln — handles the Wi-Fi interface (requires the GA1000 add-on module to be plugged into the TPP2 board);
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;
Button — monitors the onboard setup (MD) button;
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.

 

The TPP3W platform supports the standard set of variable types and functions (a.k.a. "syscalls").
