Ethernet / UDP Broadcast transport Ethernet /WinPCap transport |
- 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.
- Surrounding hardware may dictate which GPIO lines must be used as inputs and which — as outputs.
- Default CTS/RTS mapping is different for each serial port:
|
RTS |
CTS |
Port 1 |
||
Port 2 |
||
Port 3 |
||
Port 4 |
- Mapping of GA1000 and WA2000 control lines is fully flexible on the EM2000W. However, if the GA1000 or WA2000 module is installed on top of the EM2000 (so called EM2000G module combination), then the following mapping must be applied:
CS |
|
CLK |
|
DI |
|
DO |
|
RST |
Supported objects, variable types, and functions
- adc — provides access to four ADC channels
- beep — generates buzzer patterns
- bt — responsible for Bluetooth Low Energy (BLE) communications
- button — monitors the MD line (setup button)
- fd — manages flash memory file system and direct sector access
- io — handles I/O lines, ports, and interrupts
- kp — scans keypads of matrix and "binary" types
- lcd — controls graphical display panels (several types supported)
- net — controls the Ethernet interface
- pat — "plays" patterns on up to five LED pairs
- ppp — provides access to the Internet over a serial modem (4G/LTE, POTS, etc.)
- romfile — facilitates access to resource files (fixed data)
- rtc — keeps track of date and time
- ser — in charge of serial ports (UART, Wiegand, and clock/data modes)
- sock — socket communications (up to 16 UDP, TCP, and HTTP sessions)
- ssi — implements up to four serial synchronous interface (SSI) channels, supports SPI, I2C, clock/data, etc.
- stor — provides access to the EEPROM
- sys — in charge of general device functionality
- wln — handles the Wi-Fi interface (requires the GA1000 or WA2000 add-on module to be connected to the EM2000)
This platform supports the standard set of variable types and functions (a.k.a. "syscalls").
