Platform type

32-bit platform

Clock frequency (CLOCK) and clock control

Frequency is fixed at 120MHz

Available network interfaces

Ethernet (net.), Wi-Fi (wln.) , PPP (ppp.), PPPoE (pppoe.)(1)

GPIO type


UART limitations

Max practical baudrate ~460,800bps

7 bits/NO PARITY mode should not be used

Serial port FIFOs

1 byte for TX, 1 bytes for RX

Serial port line configuration

Depends on the serial port mode

Serial port interrupts and io.intenabled


RTS/CTS remapping



4 channels, 12 bits (7 bits effective)

Also available through Tibbit modules

Pulse-width modulation (PWM)

Available through Tibbit modules

GA1000 support


WA2000 support


GA1000 and WA2000 lines remapping


beep.divider calculation

beep.divider = CLOCK / (4 * desired_frq), beep.divider must be in the 2-65535 range

Device serial number

128 bytes: 64 OTP bytes + 64 fixed bytes

Flash memory configuration


Self-upgrades for the Tibbo-BASIC/C app.

Supported through the fd.copyfirmware, fd.copyfirmwarelzo, fd.copyfirmwarefromfile, and fd.copyfirmwarefromfilelzo methods

Status LEDs (LED Control Lines)

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." The sock.targetinterface and sock.currentinterface properties rely on the pl_sock_interfaces enum, whose members differ depending on the platform.

2. Surrounding board hardware and installed Tibbits dictate which GPIO lines must be used as inputs and which as outputs.

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

4. Although the platform itself supports remapping, actual "wires" connecting the system to the GA1000 or WA2000 are fixed and your mapping should reflect this:

Supported Objects, Variable Types, and Functions

  1. The kp. object can be configured to communicate with an external keypad connected to the TPP3(G2) via Tibbit modules. Only one keypad can be serviced at a time.
  2. This may be an external modem connected to the TPP3(G2), a 4G (LTE) Tibbit, or a Cat-M1/NB-IoT Tibbit plugged into the board.

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