Stairwell light code from BS1 to PHP2.50a

Hi all,

this ist me first post. I have here the old code of a stairwell light in BS1 and would like to convert it in PicBasic 2.50a. What do I have to do?

************************************************** *****************

' {$STAMP BS1}
'Typ: PBASIC-Source for stairwell light
'Name: stairwell_light.bas
'Stand: 29/11/1999

' Constants
SYMBOL tast_msk= %00010000 'Mask for button
SYMBOL lampen = 6 'Pin for lamps

' Variables
SYMBOL inp = B0 'read IO byte
SYMBOL count1 = W1 'Cycle counter
SYMBOL init = W2 '2559 Cycles to 20 ms
SYMBOL count2 = B6 'Number of keystrokes
SYMBOL count3 = B7 'Minutes
SYMBOL outflag = B8 'Flag whether pushed for a long time

' Initialization
count1 = 0 'counter for time interval = 0
count2 = 0 'Number of keystrokes = 0
count3 = 0 'Minutes = 0
outflag = 0 'Flag = 0

EEPROM 0, ($0f,$09) '$09FF in EEPROM
READ 0,init 'Read Initialwert (Lo byte)
READ 1,inp 'Read Initialwert (hi byte)
init = 256 * inp + init 'Initialwert cycle counter

' Main program
main:
inp = PINS & tast_msk 'masking of bit 3
IF inp = tast_msk THEN decr_count 'If not pressed button, then decr-count
PAUSE 300 'Pause for 300 ms
inp = PINS & tast_msk 'masking of bit 3
IF outflag = 1 THEN on 'Questions whether turned off already
IF inp <> tast_msk THEN off1 'questions on long pushing -> Lamp off
on: HIGH lampen 'Switching on light
outflag = 0 'Putting back flag for out switching cycle

IF count2 = 4 THEN main 'more as 4 times push prevent
count2 = count2 + 1 'Number of keystrokes inkr.
LOOKUP count2, (0,3,10,30,600),count3 'Minutes determine
count1 = init 'lamps on for 1 minute

decr_count:
PAUSE 20 'Pause 20 ms
IF count1 = 0 THEN off0 'if count1 = 0, then light off
count1 = count1 - 1 'Cycle counter decrementieren
IF outflag = 1 THEN L1 'In the end switching cycle
IF count3 > 1 THEN L1 'last minute reaches?
IF count1 <> 853 THEN L1 '20 second before end reaches?

off0: 'switching off normally after expiry of the time

count3 = 0
GOTO main 'Number of keystrokes = 0

off1: 'Switching off by pushing for a long time
LOW lampen

HIGH lampen

I am grateful for help

most of Stamps function will work as is, but here's some minor mods

Usually, it's nice to use the PORT name of the PIC, even if some function allow to use PIN#

LED VAR PORTA.0

There's no DIRS, depending of the PIC, you'll ned to use TRISx or TRISIO

TRISA=0 ' set all PORTA i/o to output

IN PBP you don't need to alias to a Byte,bit, word variable, you just define it

MyByteA VAR BYTE
MyBitVar var BIT
MyWordVar var WORD

In the PBP manual, have a look at section 10

Welcome on the forum ;)

PS: when you ask a question, always tell which PIC model you're going to use, if you have any schematic, post it too. More info we have, better the replies will be.
