Bot Board II testing program, Problem

Hi

I have a Bot Board II with a BASIC Atom (not Pro) micro-controller. I am going through the BASIC Atom Pro Programming Tutorial.

In section 9) I try to download the “Bot Board II testing program” to the microcontroller, but when it is compiling I get a syntax error in line 31. Does anyone know what this is and how to fix it? I have just startet experimenting with the BASIC Atom so I don’t have much knowledge of the program language and such yet.

[code]nn var byte

ledA var bit
ledB var bit
ledC var bit

butA var bit
butB var bit
butC var bit

prev_butA var bit
prev_butB var bit
prev_butC var bit
temp var word

BUTTON_DOWN con 0
BUTTON_UP con 1

ledA = 0
ledB = 0
ledC = 0
butA = 0
butB = 0
butC = 0

nn = 0

'Wiggle LEDs
main:

adin 16,temp
serout S_OUT,i57600,[dec6 temp\6," ",13]

if (butA = BUTTON_DOWN) AND (prev_butA = BUTTON_UP) then
	nn = nn + 1
	sound P9,[5\2500]
	low P9
endif
if (butB = BUTTON_DOWN) AND (prev_butB = BUTTON_UP) then
	nn = nn - 1
	sound P9,[10\1000]
	low P9
endif
if (butC = BUTTON_DOWN) AND (prev_butC = BUTTON_UP) then
	nn = 0
	sound P9,[10\4000]
	low P9
endif

ledA = nn.BIT0
ledB = nn.BIT1
ledC = nn.BIT2

if ( nn.BIT0 = 1 ) then
	high p0
	high p8
	high p4
else
	low p0
	low p8
	low p4
endif
if ( nn.BIT1 = 1 ) then
	high p1
	high p5
else
	low p1
	low p5
endif
if ( nn.BIT2 = 1 ) then
	high p2
	high p10
	high p6
else
	low p2
	low p10
	low p6
endif
if ( nn.BIT3 = 1 ) then
	high p3
	high p7
	high p11
else
	low p3
	low p7
	low p11
endif


pause 50

prev_butA = butA
prev_butB = butB
prev_butC = butC
gosub button_led_control

goto main

'Subroutine to read the buttons and control the LEDs. Button states are put in
'variables butA, butB, and butC. LED states are read from variables ledA, ledB,
'and ledC.
button_led_control:
'Make P4-P6 inputs to read buttons. This turns the LEDs off briefly
input p12
input p13
input p14
butA = IN12
butB = IN13
butC = IN14

'Output LOW to each LED that should be on
if ledA = 1 then
	low p12
endif
if ledB = 1 then
	low p13
endif
if ledC = 1 then
	low p14
endif

return[/code]

by line 32 are you referring to

serout S_OUT,i57600,[dec6 temp\6," ",13]

?
one thing i noticed is that you have not defined S_OUT. I am guessing that S_OUT is supposed to be a variable that indicates which I\O pin to use for sending the serial data. you must define it firstly so that the program knows that S_OUT is a symbol, and secondly so that it knows what S_OUT represents. so you need to add a statement somewhere before it executes the SEROUT command that looks something like this:

S_OUT con 0

(0 can be swapped out with whatever I\O pin you are using)
alternatively, you can replace the S_OUT in your serout command directly with the I\O pin that you want to use.

S_OUT and S_IN are predefined constants used to reference the in and out serial programming pins on an Atom/Atompro module.

The code is for the Atom Pro. I believe the error is actually the A to D input. The Atom has the A to D on pins AX0, AX1, AX2, AX3. So you need to change the program. Change adin 16,temp to adin ax0,2,ad_ron,temp.
