Bus Pirate + FSA03 GPS How to:

Ril3y — Fri, 02 Apr 2010 19:00:22 +0000

I have a few projects that I would like to include GPS data in, in the near future. So I went ahead and picked up a nice ublox based GPS. YOu can get it here: I wanted to used it right away. So rather than coding up some AVR C or arduino stuff I decided to use my bus pirate for the job. Here is the settings I used to get it up and going:

Hardware Settings Table:

Hardware Pinout Table
BPv3 to	FSA03 (GPS)
3.3v to	3v
MISO to	TXL
MOSI to	RXL
GND	GND

Mode: UART
SPEED: 9600
Then default everything else:

Bus Pirate v3

Firmware v3.1

DEVID:0×0447 REVID:0×3003 (A3)

10. 31250 (MIDI)

Data bits and parity:

1. 8, NONE *default

2. 8, EVEN

3. 8, ODD

4. 9, NONE

Stop bits:

1. 1 *default

2. 2

2. Idle 0

Select output type:

1. Open drain (H=Hi-Z, L=GND)

2. Normal (H=3.3V, L=GND)

(1) >

READY

POWER SUPPLIES ON

So you can see I am getting hex data. Note you can just enter { in the BPv3 command prompt to enable reading from the UART port constantly. However for copy paste issues for this post I chose to issue single byte read (r). Next is to write some arduino or avr code to translate this NEMA standard output to a human readable format. (Yes I know there are libs available however I prefer to learn by doing) So up next Code!

Buss Pirate V3 Basics on Mac

Ril3y — Mon, 16 Nov 2009 23:23:27 +0000

Today I got home from my day job and found at small package with custom stamps all over it. Needles to say this was the V3 Bus Pirate that I orded about 3 – 4 weeks ago. After I took it out of the package I wanted to test it out a bit. Kicked on the Macbook Air and hooked it up. The quick and easy way to connect to the Bus Pirate V3 via OSX is just to do this:

screen /dev/tty.usbserial-A600aSlz 115200

After that you should see something like this: (If you don’t see anything just hit enter a few times)

Once there I typed in capitol M and it quickly displayed a listing of supported protocols seen here:

So just push something like 9 and it will change the mode of the bus pirate to PC KEYBOARD mode. Very cool stuff. Will blog more on it after my work on the contraptor.org project for the lightning talks @hacdc is over.

OpenWRT + Router Station Pro + Arduino = Fun

Ril3y — Wed, 30 Sep 2009 16:06:59 +0000

Around 11PM last night I finally was able to get all the Arduino Hardware talking to my Openwrt Router Station Pro Installation. These are the packages you need to have on your system. (if you built your own firmware with theses great! otherwise just opkg install them)

Like So:

root@OpenWrt:~# opgk install usbutils

Install the rest of these packages the exact same way:

usb-ohci

kmod-usb-serial-ftdi

kmod-usb2

kmod-usb-serial(Note: these packages are needed if you want to us the MMC/SD Card on the RS PRO)

kmod-usb-storage

kmod-mmc

Once that is done you can issue the lsusb command to see if your system recognizes the Arduino FTDI interface. You should see something like this.

Bus 002 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 003: ID 05e3:0723 Genesys Logic, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

If you do not see the UART (FTDI) device go ahead and reboot your system and it should come up. If it does not you are missing a package email me we can see whats up.

Will add more later but here some screenshots of the system working.
