EM1001, EM1001W, and EM1001N Platforms
Hardware devices covered by this platform
- EM1001 programmable IoT board (optionally, with GA1000 or WA2000 add-on device).
- Other devices incorporating the EM1001 board.
This section covers three separate platforms:
- EM1001 — does not support any wireless modules.
- EM1001W — supports the GA1000 Wi-Fi add-on.
- EM1001N — provides limited support for the WA2000 add-on (Wi-Fi only; BLE not supported).

Comments:
- Default PLL state after the external reset depends on the PM pin of the EM1001(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:
|
RTS |
CTS |
Port 1 |
||
Port 2 |
||
Port 3 |
||
Port 4 |
- Mapping of GA1000 and WA2000 control lines is fully flexible on the EM1001W. However, if the GA1000 or WA2000 module is installed on top of the EM1001, then the following mapping must be applied:
CS |
|
CLK |
|
DI |
|
DO |
|
RST |
- Older EM1001 and EM1001W devices did not contain the serial number. To find out if your EM1001(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 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);
- 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").
