Here's some Bascom Basic code
« on: April 30, 2007, 01:39:00 AM »
Here's some simple code for making a left wall following robot, using Bascom Basic. You might have to slightly modify it for your application, but its a great place for a new person to start.

Code: [Select]
' Code by F Johnston, use it to build a bot
'Follow left wall maze code, or it could be used with slight adjustments to make a line follower.
'
'This code requires the use of 3 IR sensors, a Barton board or a similar Atmel Mega 8 controller, and
'a skid steering platform.
'
$crystal = 1000000 'internal crystal
$regfile = "M8def.dat" 'micro config file
' Sensor ports are defined thus
' 1 = PINC.3 (Chan 3) Not used
' 2 = PINC.2 (Chan 2) Center_sensor
' 3 = PINC.1 (Chan 1) Left_sensor
' 4 = PINC.0 (Chan 0) Not used
' 5 = PINC.5 (Chan 5) Not used
' 6 = PINC.4 (Chan 4) Not used
Config Portb = Output
Config Portc = Output
Config Portd = Output
Config Timer1 = Pwm , Prescale = 8 , Pwm = 8 , Compare A Pwm = Clear Down , Compare B Pwm = Clear Down

Hello to all
I make a line follower robot but have problems in its source code.
I'm working with code vision and wrote the program using c language. I want Rbatm intersecting lines, raster, breaks, rings and ... But the simple code could only Bnvsm. I have no experience in the field of robotics and this is important for me and I need the source code if you code a line follower robot has developed a passion for me.
I'm not fluent in English and hard to write these sentences. Forgive me if it is wrong in this sentence.
Please send to my mail.
Thanks
