    Hi Mike, Welcome to the forum. You have analog stuff to turn off on PortA.
    ADCON0 = 0 'disable A/D module disabled
    ADCON1 = 127 'AN1 through AN6 as digital
    Hmmm no CMCON or CMCON0 . . . . still looking . . . .
    Ok now I looked at the Data sheet on the junebug. PortA is used as outputs, so let's start here:
    Code:
    ADCON0  = 0 'disable A/D module disabled       
    ADCON1  = 127 'AN1 through AN6 as digital 
    DEFINE OSC 4 ' or some other number as fits you
    
    PortA = %00000000 ' a zero for each pin drives LATA registers all low so when made an output they will all be @ ground
    TRISA = %00000000 ' All portA pins as outputs
    PortA = %10000001 , Light 1 on
    Pause 200
    TRISA.7 = 1 ' Tristates PortA.7 
    PortA = %01000000 'Light2 on
    pause 200
    TRISA = %00000001 ' Tristates RA0
    portA = %01000000 ' Light3 on
    and so on, here is untested code
    Different methods shown above.
    A better way might be to use 2 lookup tables and a for next loop to display this somewhat unusual LED Array.
    Code:
    ADCON0  = 0 'disable A/D module disabled       
    ADCON1  = 127 'AN1 through AN6 as digital 
    DEFINE OSC 4 ' or some other number as fits you
    TrisVar Var Byte
    PortVar Var Byte
    index   Var Byte
    PortA = %00000000 ' a zero for each pin drives LATA registers all low so when made an output they will all be @ ground
    TRISA = %00000000 ' All portA pins as outputs
    main:
        For index = 0 to 5
    
            lookup index,[%00000000,%00000000,%00000001,%00000001,%01000000,%01000000], TrisVar
            lookup index,[%00000001,%01000000,%01000000,%10000000,%10000000,%00000001], PortVar
            PortA = PortVar
            TrisA = TrisVar
            Pause 200
        next index
    GoTo Main
    end

    If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.
    .
    Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves
    .
    There simply is no "Happy Spam" If you do it you will disappear from this forum.
