Display type selection and line remapping

Type selection and line remapping supported, but the hardware dictates the use of "Solomon SSD1305" driver and a predefined control line arrangement

Green status (SG) LED

Red status (SR) LED

Yellow Ethernet status (EY) LED

An LED bar consisting of five blue LEDs

Debug communications

Ethernet / UDP Broadcast transport

Ethernet /WinPCap transport



1.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.

2.Surrounding board hardware dictates which GPIO lines must be used as inputs and which — as outputs.

3.The hardware of this platform supports serial channels, which means that CTS/RTS and DTR/DSR pairs of the DB9 connector can also be used as RX/TX pairs of additional serial channels. Therefore, it is up to you to decide which lines are used as RTS and CTS, and which channels they will belong to. Proper mapping will be required to implement each particular arrangement.

4.Although the platform itself supports remapping, actual "wires" connecting the system to the GA1000 are fixed and your mapping should reflect this:



15- PL_IO_NUM_15


14- PL_IO_NUM_14


12- PL_IO_NUM_12


13- PL_IO_NUM_13


11- PL_IO_NUM_11


Supported Objects, variable types, and functions

Sock — socket communications (up to 16 UDP, TCP, and HTTP sessions);

Net — controls the Ethernet port;

Wln — handles the Wi-Fi interface (requires GA1000 add-on module, i.e. "G" device option);

Ser — in charge of the serial ports (on this device, serial channels of the RS232 port);

Io — handles I/O lines, ports, and interrupts;

Lcd — controls the 96x32 monochrome OLED display (therefore, requires the "D" device option);

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 a pair of LEDs;

Beep — generates buzzer patterns;

Button — monitors the MD line (setup button);

Sys — in charge of general device functionality.



As all displays of this type, the DS1101's OLED display has a limited life span. There will be a decrease in the display brightness after ~10000 hours of operation. To prolong display life, use the lcd.lock method to turn the display off whenever possible. Display image is preserved when the display is "locked".


This platform supports the standard set of variable types and functions (a.k.a. "syscalls").
