Serial Port Settings
The default serial port settings for the board are:
Baud 115,200
Bits 8
Parity N
Stop Bits 1
Handshake None
Standard FTDI Cable
The debug cable is a standard FTDI to TTL cable. Make sure you get the 3.3V version. You can purchase this from several different sources including but not limited to:
Pin 1 on the cable is the black wire and connects to pin 1 on the board, the pin with the white dot next to it.
Adafruit 4 Pin Cable (PL2303)
One is from *Adafruit. This is a Prolific chipset based cable. Some people have reported issues with the cable causing some issues with data corruption. You experience may vary. You will need to install the Prolific drivers. Those can be downloaded from Adafruit.
Board | Cable |
---|---|
Pin 1 (GND) | Black (GND) |
Pin 4 (RX) | Green (TX) |
Pin 5 (TX) | White (RX) |
NOTE:
You will also find an extra RED wire on this cable that supplies 5V @ 500mA which could power the board if connected to one of the VDD_5V pins (P9_05, P9_06). Just leave it unconnected.
FTDI 3 Pin Cable
You can purchase the another version direct from *FTDI
This cable only has three wires for connection. You can find the datasheet and a picture at *Cable
Board Wire Function Pin 1.....Black......Ground
Pin 4.....Yellow.....Receive
Pin 5.....Orange.....Transmit
NOTE: The naming of the signals reflect those of the cable. The swapping of TX and RX takes place on the board.
Olimex 3 Pin Cable (PL2303)
A third version is sold by *Olimex
Board Wire Function Pin 1.....Blue......Ground
Pin 4.....Red.......Transmit
Pin 5.....Green.....Receive
NOTE: The naming of the signals reflect those of the cable. The swapping of TX and RX takes place on the board.
