EM1000, EM1000W, and EM1000N Platforms

Hardware devices covered by this platform

EM1000 programmable IoT module (optionally, with GA1000 or WA2000 add-on device).
DS10XX programmable industrial controllers (now obsolete).

This section covers three separate platforms:

EM1000 — does not support any wireless modules.
EM1000W — supports the GA1000 Wi-Fi add-on.
EM1000N — provides limited support for the WA2000 add-on (Wi-Fi only; BLE not supported).

RAM	22,271 bytes for application variables and data
Flash	983,040 bytes for application and data storage (shared flash memory)*

Comments:

Default PLL state after the external reset depends on the PM pin of the EM1000(W).
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:

Mapping of GA1000 and WA2000 control lines is fully flexible on the EM1000W. However, if the GA1000 or WA2000 module is installed on top of the EM1000, then the following mapping must be applied:

Older EM1000 and EM1000W devices did not contain the serial number. To find out if your EM1000(W) has the serial number onboard, try to read this serial number with the sys.serialnum R/O property. If this property returns an empty string, then the serial number is not present. Sys.serialnum returns all 128 bytes of the serial number. First 64 bytes are one-time-programmable (OTP) with the sys.setserialnum method.

Wln — handles the Wi-Fi interface (only available on EM1000W and EM1000N platforms, requires GA1000 or WA2000 add-on devices respectively);

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);

These platforms support the standard set of variable types and functions (a.k.a. "syscalls").
