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 hardware may dictate 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.

4.Connect the GA1000 add-on module as follows (also see schematic diagram C in Connecting GA1000):

CS

7- PL_IO_NUM_7

CLK

6- PL_IO_NUM_6

DI

5- PL_IO_NUM_5 (yes, DI and DO lines are on the same GPIO line)

DO

RST

Choose any suitable GPIO or use NAND gates to generate reset

 

Supported Objects, variable types, and functions

Sock — socket communications (up to 16 UDP, TCP, and HTTP sessions);

Net — controls the Ethernet port;

Wln — handles the Wi-Fi interface (requires GA1000 add-on module);

Ser — in charge of the serial port (UART, Wiegand, and clock/data modes);

Io — handles I/O lines, ports, and interrupts;

Fd* — manages flash memory file system and direct sector access (requires an externally connected flash IC);

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 a pair of LEDs;

Button — monitors the MD line (setup button);

Sys — in charge of general device functionality.

* Fully supported with the exception of fd.copyfirmware. Disabled by default — enable it in Project Settings -> Customize.

 

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 EM500W platform.
