Independent

RTS/CTS remapping

Supported(3)

ADC

N/A

N/A

GA1000 support

YES

WA2000 support

Supports Wi-Fi, BLE is not supported

GA1000 and WA2000 lines remapping

Supported(4)

beep.divider calculation

beep.divider = CLOCK / (2 * desired_frq)

Recommended buzzer frequency divider

2,700Hz, beep.divider = 16200  (with PLL ON)

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

28 bytes for MAC and device password storage

Device serial number

128 bytes: 64 OTP bytes + 64 fixed bytes

Flash memory configuration

Shared

Self-upgrades for Tibbo BASIC/C applications

Supported through fd.copyfirmware, fd.copyfirmwarelzo, and fd.copyfirmwarefromfile 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 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:
