When you first start it's a pretty steep learning curve isn't it!
You were close, slightly modded code
'--------------------------------------------------------------------
' FLASHER.BAS
'--------------------------------------------------------------------
Device = 16F616
;Config IOSCFS_4MHZ, CP_ON, MCLRE_OFF, PWRTE_ON, WDT_OFF, INTOSCIO, BOR_ON
Declare Xtal = 4
Declare Create_Coff = On
Declare All_Digital = True
Symbol LED = PORTC.3
'TRISA = %11001111 ' TRISA set the state of APort
'PORTA = %00000000 ' PORTA is the data either read or write
TRISC = %00000000
'PORTC = %00000000
Loop:
Toggle LED
DelayMS 1000
GoTo Loop
So, in essense
Let the fuses default untill you need to change them.
The "All digital" takes care of the anologue stuff
You don't need to setup the A port
You don't need the PORTC command to write, the Toggle LED will do that for you.
