EM1000 and EM1000W Platforms

Top  Previous  Next

The difference between the EM1000 and EM1000W platforms is that the EM1000W additionally includes the Wi-Fi  (wln.) object (requires an external GA1000 add-on module). All other features of these two platforms are exactly the same.

These platforms are used for two devices:

EM1000 and EM1000G (EM1000+GA1000)

DS10XX and DS10XXG (DS10XX+GA1000)


Memory space and key info


22,271 bytes for application variables and data


983,040 bytes for application and data storage (shared flash memory)*


2040 bytes for application data

*Some earlier devices had only 458,752 bytes of flash memory available

Ethernet /WinPCap transport



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

2.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.

3.Surrounding hardware may dictate which GPIO lines must be used as inputs and which — as outputs.

4.Default CTS/RTS mapping is different for each serial port:




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)


5.Mapping of GA1000 control lines is fully flexible on the EM1000W. However, if the GA1000 module is installed on top of the EM1000 (so called EM1000G module combination), then the following mapping must be applied:


49- PL_IO_NUM_49


53- PL_IO_NUM_53


52- PL_IO_NUM_52


50- PL_IO_NUM_50


51- PL_IO_NUM_51


6.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.


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 (only available on the EM1000W platform, requires GA1000 add-on module);

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;

Button — monitors the MD line (setup button);

Sys — in charge of general device functionality.


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