EM1206, EM1206W, and EM1206N Platforms

Hardware Devices Covered by This Platform

• EM1206 programmable IoT module (optionally, with a GA1000 or WA2000 wireless add-on module)
• Other devices incorporating the EM1206

This section covers three separate platforms:

• EM1206 — does not support any wireless modules
• EM1206W — supports the GA1000 Wi-Fi add-on module
• EM1206N — provides limited support for the WA2000 add-on (Wi-Fi only; BLE is not supported)

Memory Space and Key Info

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

1. The sock.allowedinterfaces property refers to the Ethernet interface as "NET," Wi-Fi as "WLN," PPP as "PPP," and PPPoE as "PPPOE." The 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. Notice that CTS and RTS lines in default mapping interfere with each other. Do remember to select meaningful mapping for these lines!

4. Mapping of GA1000 and WA2000 control lines is fully flexible on the EM1206W. However, if the EM1206EV board is used, then the following mapping must be applied:

5. Older EM1206 and EM1206W devices did not contain the serial number. To find out if your EM1206(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. This property returns all 128 bytes of the serial number. The first 64 bytes are one-time programmable (OTP) with the sys.setserialnum method.

Supported Objects, Variable Types, and Functions

• beep — generates buzzer patterns
• 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 (GPRS, POTS, etc.)
• pppoe — provides access to the Internet over an ADSL modem
• 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 (only available on the EM1206W and EM1206N platforms, requires the GA1000 or WA2000, respectively)

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