PIC18F4620 Write Command

[csooi08]

Hi! Good day! Henrik,

So why did you try writing to $4205 then?

I am using the program which my senior written and him already left the company. So, i not sure what is going to be happen using that command. Now, i understand from your explaination.

Sorry for making you confuse.

Let me show u the exact code that found error part.

'Extract part of the code that have an error
STEP_SELECT:

    read $101,STEP_ADDRESS
    STEP_ADDRESS = STEP_ADDRESS + 1
    WRITE $101,STEP_ADDRESS

    NG_COUNTER = 0
    write $103,NG_COUNTER

    DEBUG "CHECKING STEP_ADDRESS = ",DEC STEP_ADDRESS,10,13
'Here, the result still can see at hyperterminal screen 

    if STEP_ADDRESS = 1 then MULTIMETER_JUDGE 
    if STEP_ADDRESS = 2 then ADDR_30       
    if STEP_ADDRESS = 3 then ADDR_31       
    if STEP_ADDRESS = 4 then ADDR_32       
    if STEP_ADDRESS = 5 then ADDR_33       
    if STEP_ADDRESS = 6 then ADDR_34       
    if STEP_ADDRESS = 7 then ADDR_35       
    if STEP_ADDRESS = 8 then ADDR_36       
    if STEP_ADDRESS = 9 then ADDR_37       
    if STEP_ADDRESS = 10 then ADDR_38      
    if STEP_ADDRESS = 11 then ADDR_39      
    if STEP_ADDRESS = 12 then ADDR_40     
    if STEP_ADDRESS = 13 then ADDR_41      
    if STEP_ADDRESS = 14 then CHARGING_CHECK      
    if STEP_ADDRESS = 15 then CHARGING_CHANGE_DC  
    if STEP_ADDRESS = 16 then END_PROCESS 

goto STEP_SELECT

CHARGING_CHECK:
    HIGH RLY5_1_CHARGING_SUPPLY         
    PAUSE 1000
    LOW RLY5_1_CHARGING_SUPPLY         
    goto MULTIMETER_JUDGE
goto STEP_SELECT

MULTIMETER_JUDGE:
    READ $101,STEP_ADDRESS:WRITE $101,STEP_ADDRESS

    IF STEP_ADDRESS = 0 then 
        DEBUG "STEP_ADDRESS =  ",DEC STEP_ADDRESS,10,13
'Here, the result still can see at hyperterminal screen 
        serOut GPIB_TX,N9600,["F5,R5,PR2,CO1,HI+00.200E-3,LO-01.000E-3",13]
        pause 500
        GOTO CONT_CURRENT_CHECK
    endif 

    IF STEP_ADDRESS = 1 and VERSION_SW = 1 then 
        DEBUG "(J4) STEP_ADDRESS =  ",DEC STEP_ADDRESS,10,13
'Here, the result still can see at hyperterminal screen 
    	SerOut GPIB_TX,N9600,["F5,R7,PR2,CO1,HI+090.00E-3,LO+070.00E-3",13]
        pause 500
        GOTO CONT_CURRENT_CHECK
    ENDIF    
    
    IF STEP_ADDRESS = 14 THEN 
        DEBUG "STEP_ADDRESS =  ",DEC STEP_ADDRESS,10,13
'At here, the result can't see at hyperterminal screen...i wonder why this happen? 
    	SerOut GPIB_TX,N9600,["F5,R7,PR2,CO1,HI+420.00E-3,LO+380.00E-3",13]
        pause 500
        GOTO CONT_CURRENT_CHECK
    ENDIF

CONT_CURRENT_CHECK:

I only show the part of the program that error occurred. Hopefully u can understand that.
TQ and BR
