USB Serial Driver using Android USB Host API

• Java source code
• no root
• baudrate : 9600 - 230400 (be able to setting immediate baudrate number)
• support FTDI chips (FT232RL, FT232H, FT2232C/D/HL, FT4232HL FT230X, REX-USB60F/MI(FT232BL) checked)
• support any channels (FT2232X:2ch, FT4232X:4ch)
• support CDC-ACM(beta)
• like Arduino library's interface

Connection

Android [USB A port] --- [USB B port] FTDI Chip

• requirement
• Android : version 3.1 or upper and have an USB host port
• Board : FTDI Chip or CDC-ACM(beta)

• Library Project
  FTDriver : Driver for connecting an FTDI chip to Android USB host port

• Sample Projects
  FTSampleTerminal : very simple terminal
  FTSerialCSV : serial communication with a Genet educational board (www.genet-nara.jp) in CSV format (Thanks for Heima Hayashida)

read n bytes

byte[] rbuf = new byte[n];
len = mSerial.read(rbuf);

read n bytes from channel p

byte[] rbuf = new byte[n];
len = mSerial.read(rbuf, n, p)

write n bytes

byte[] wbuf = new byte[n];
...(set wbuf)
len = mSerial.write(wbuf,n);

write n bytes to channel p

byte[] wbuf = new byte[n];
...(set wbuf)
len = mSerial.write(wbuf,n,p);

close

mSerial.end();
