Programming with PicBasic Compiler

Hi, Iam trying to compile code given for the insectronics bot with the pic basic compiler but only get error messages (new to programming chips).
Eg. Here is the code:

temp var byte ' initialize variables
freq var byte
m_servo var byte
l_servo var byte
r_servo var byte

portb.7 = 0 ' set initial logic states to 0
portb.6 = 0
portb.5 = 0

freq = 13 ' delay value

start:

m_servo = 140 ' set servo position values
l_servo = 140
r_servo = 140

gosub servo

goto start


servo: ' servo positioning subroutine
for temp = 1 to 10
pulsout portb.7,m_servo
pulsout portb.6,l_servo
pulsout portb.5,r_servo
pause freq ' set frequency between 50 - 60 Hz
next temp
return

If I try to compile this is the error messages I get:

error servo- ~1.bas,8:':'or '=' expected (token 'var')
error servo- ~1.bas,9:':'or '=' expected (token 'var')
error servo- ~1.bas,10:':'or '=' expected (token 'var')
error servo- ~1.bas,11:':'or '=' expected (token 'var')
error servo- ~1.bas,12:':'or '=' expected (token 'var')
error servo- ~1.bas,14:'illegal character '.'
error servo- ~1.bas,14:':'or '=' expected (token '7')
etc....etc..etc

I will appreciate any help
PS I use a 16F84A chip.

Actually your posted example code compiles without error with the command line...

pbp -p16f84a test

Code:

---

        temp var byte ' initialize variables
        freq var byte
        m_servo var byte
        l_servo var byte
        r_servo var byte

        portb.7 = 0 ' set initial logic states to 0
        portb.6 = 0
        portb.5 = 0

        freq = 13 ' delay value

start:

        m_servo = 140 ' set servo position values
        l_servo = 140
        r_servo = 140

        gosub servo

        goto start


servo: ' servo positioning subroutine
        for temp = 1 to 10
                pulsout portb.7,m_servo
                pulsout portb.6,l_servo
                pulsout portb.5,r_servo
                pause freq ' set frequency between 50 - 60 Hz
                next temp
                return

Ahh... pain... just realised your using PBC not the pro version... you are going to have to go through your manual and assign your variable names and Pins to allowed variables and pins.

Thanks! I will try again.

hi raycher, was just wondering what your codes was used for? kinda interested in similar projects to do with servomotors. i've only just recently built a walking gait robot using servo motors with the help of melanie.

Looks like the code from that book with the 3 servo walking robot that I mentioned in the other thread.

That book is also written in PCB Pro so converting it to basic would take a little more effort.

Everyone building robots these days?

Hi, the code were used for a insec bot. I used the book called "Insectronics" by Karl Williams to built a six legged insec - works pretty well once one can program the chip.
