;Name: Day Finder
;Version: DAYFIND
;Description: This will allow you to determine the date for a given day of the week and vice-versa.
;by John A. Toebes, VIII
;
;Press the prev/next buttons to advance by a single day. Press SET to access the ability to advance/backup by
;weeks, months, days, and years. The MODE button advances through those different states
;
;TIP: Download your watch faster: Download a WristApp once, then do not send it again. It stays in the watch!

; (7) State Table 1 Handler
; This is called to process the state events.
; We see SET, RESUME, USER3, TIMER2, DNANY4, and UPANY4 events
; We use the USER3 to trigger a delay which fires off a TIMER2 sequence of events.
; This allows us to have the PREV/NEXT buttons repeat for advancing the WEEK and YEAR
; since we can't use the UPDATE routines for them.

bra WEEKLOOPCHK ; And continue the loop
LASTWEEK
jsr DECREMENT_SCAN_DATE ; Going backwards, retreat by one day
WEEKLOOPCHK
dec COUNTER ; Count down
tst COUNTER ; See if we hit the limit
bne WEEKLOOP ; and go back for more
; (9) Fake repeater
; This code is used for the Day of week and year modes where we want to have a
; repeating button, but the system routines won't handle it for us
; It works by posting a USER3 event which has a timer of about 1/2 second.
; After that timer expires, we get a timer2 event which then repeats every tic.
; The only thing that we have to worry about here is to not go through this
; every time so that it takes 1/2 second for every repeat.
SETUP_LAG
brset B_SCANNING,FLAGBYTE,INLAG ; If we were already scanning, skip out
bset B_SCANNING,FLAGBYTE ; Indicate that we are scanning
lda #EVT_USER3 ; and post the event to start it off

; (10) Update routine usage

sta UPDATE_MIN
lda #MONTH_DEC ; and the top end is December (INCLUSIVE)

lda #UPD_HMONTH ; We want the HALF-MONTH udpate function

bra SEL_UPD ; Go do it
DO_UPD_DAY ; 2 - Handle the day
lda #1 ; 1 is the first day of the month
sta UPDATE_MIN
jsr GET_SCAN_MONTHLEN ; Figure out how long the month is
sta UPDATE_MAX ; and make that the limit
lda #UPD_HDAY ; We want the HALF-DAY update function
ldx #SCAN_DAY ; to update the SCAN_DAY variable
SEL_UPD
jsr START_UPDATEP ; And prepare the update routine
bset 4,BTNFLAGS ; Mark that the update is now pending

; (11) Making the mode button work
; when they press the mode button, we want to cycle through the various choices
; on the display.

NOCLEAR
clr BTNFLAGS ; Turn off any scrolling banners
lda #ROW_TD23 ; Turn off the dash from the week blink
sta DISP_ROW
bclr COL_TD23,DISP_COL
jsr SHOW_DATE ; Display the date
; (12) Establishing a blink routine
; This makes the appropriate section of the display blink based on what we are changing
lda DIGSEL ; Get the digit we are on
beq DO_BLINK_DOW ; 0 -> Update Day of week
cmp #2
blo DO_BLINK_MONTH ; <2 = 1 -> Update month
beq DO_BLINK_DAY ; 2 - Update day of month
DO_BLINK_YEAR ; 3: Year
; (13) Calling BLINK_SECOND
; For BLINK_SECONDS, the UPDATE_PARM points to the 2 character format for the year.
ldx SCAN_YEAR ; Get our year
jsr GETBCDHI ; And extract out the high digit of it
sta YEAR_DIG1 ; Save that away
ldx SCAN_YEAR ; Do it again
jsr GETBCDLOW ; to get the low digit
sta YEAR_DIG2 ; and save that away
ldx #YEAR_DIG1 ; the parm points to the first digit
lda #BLINK_SECONDS ; and we want a BLINK_SECONDS function
bra SETUP_BLINK ; so do it already
DO_BLINK_DOW ; 0: Day of week:
; (14) Calling BLINK_SEGMENT
; Unfortunately, there is no blink routine to blink the upper two letters on the display.
; To get around this, I have chosen to blink a single segment on the display (the dash
; after the day of the week). This routine was designed to blink the AM/PM or other
; symbols, but it works quite fine for our purposed. You need to set UPDATE_POS to have
; the row to be updated and UPDATE_VAL holds the mask for the COLUMS to be XORed.
; In this way, you might have more than one segment blinking, but there are few segments
; on the same row which would achieve a reasonable effect.
; UPDATE_POS ROW_TD23
; UPDATE_VAL (1<<COL_TD23)
lda #ROW_TD23
; We want to blink the DASH after the day of week sta UPDATE_POS
; Store the ROW for it in UPDATE_POS lda #(1<<COL_TD23)
; Get the mask for the column sta UPDATE_VAL
; And store that in UPDATE_VAL lda #BLINK_SEGMENT
; We want a BLINK_SEGMENT function bra SETUP_BLINK
; and get to it.
DO_BLINK_MONTH ; 1: Month
; (15) Calling BLINK_HMONTH, BLINK_HDAY
; These are the normal boring cases of calling the blink routine. They simply need the
; address of the byte holding the value to blink and the function to blink them with.
; UPDATE_PARM - Points to the month
lda #BLINK_HMONTH ; We want a BLINK HALF-MONTH function
ldx #SCAN_MONTH ; to blink our month
bra SETUP_BLINK ; and do it
DO_BLINK_DAY ; 2: Day
; UPDATE_PARM - Points to the day
lda #BLINK_HDAY ; We want a BLINK HALF-DAY function
ldx #SCAN_DAY ; to blink our day
SETUP_BLINK
jsr START_BLINKP ; Request the blink function
lda digsel ; Figure out which one we are blinking
lsla ; *2
lsla ; *4
lsla ; *8
add #S8_WEEK-START ; And use that to index the banner to put on the bottom
jsr BANNER8
bset 2,BTNFLAGS ; Mark a blink routine as pending
rts
;
; (16) This is the main initialization routine which is called when we first get the app into memory
