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 hardware may 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.Mapping of GA1000 control lines is fully flexible on the EM2000W. However, if the GA1000 module is installed on top of the EM2000 (so called EM2000G module combination), then the following mapping must be applied:
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;
•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;
•Sys — in charge of general device functionality.
•Adc — provides access to four ADC channels.
