SUMO AVENTURE

2009-05-22T06:44:00.000-07:00

This blog is intented for the documention of my development of a SUMOBOTS

Here's a Kamiakin HS SUMO

http://school.ksd.org/kamiakin/staff_pages/ct_pcts/semester_project/semproj_bots.htm

I'm beginning by trying to connect to the ATMEL8 chip using a usb device.
Presenlty I'm using the following test interface:

ATMEL AVR USB using Gentoo Linux

2009-05-21T04:21:00.000-07:00

This entry is intended to document my development of an Atmel AVR Atmega8 USB interface using Gentoo Linux.
I've installed "avrdude" and the avrusb utilities. Here are a few links:
AVR Setup
http://www.ladyada.net/learn/avr/setup-unix.html

AVR DUDE
http://www.ladyada.net/learn/avr/avrdude.html

I'm presently using a protostack.com usb interface and a protostack development board.

This is my current error:cwc@tma ~/avrdude $ avrdude -c usbasp -p atmega8 -U flash:w:test_leds.hex

avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude done. Thank you.

I'm going to check my solder job on the dev boards.

TC4424 WITH H-BRIDGE

2009-04-16T18:57:00.000-07:00

After a lot of trial an error and a suggestion from David Cook. (http://www.robotroom.com/)
I got the h-bridge to work with a TC4424 Chip.
I'm using the parallel port on a computer
running Fedora Core 7. I also run the code from my laptop running
an up to date version of Gentoo. I'm using gcc c now to talk to the chip.
My next goal is to write some code to control some motors from the
RS-232 port. ciao cwc
