Wizard23/USB EEG with Arduino HowTo

this is just a writeup of some tricks I learned from User:MariusKintel

1. installing avr gcc

sudo apt-get install gcc-avr avr-libc

1. removing dmx drivers

sudo rmmod dmx_usb

1. finding out how big a hex file is on the atmel

avr-size main.hex

1. programming the bootloader

sudo make -f Makefile.usbasp DEVICE=atmega8 HEXFILE=ATmegaBOOT.hex

1. flashing arduino

avrdude -F -p atmega8 -P /dev/ttyUSB1 -c stk500 -b 19200 -U flash:w:main.hex

1. reading hex back

avrdude -F -p atmega8 -P /dev/ttyUSB0 -c stk500 -b 19200 -U flash:r:back.hex:i

   #define PORTB_INIT          0x16 // 0b00010110
   #define DDRC_INIT           0x00 // 0b00000000
   #define PORTC_INIT          0x00 // 0b00000000
   #define DDRD_INIT           0x02 // 0b00000010
   #define PORTD_INIT          0x2f // 0b00101111

1. testen

screen /dev/ttyUSB0 115200

quitting: ctr A + K + Y
