Hi All,
I've tried to use odyssey to program PIC18F4550.
I've created the proper pic.conf section:
[PIC18F4550]
deviceid=0x1200
deviceidmask=0xffe0
memtype=flash
wordsize=16
codesize=16384
eesize=256
progcount=1
progmult=0
progtime=5000
erasetime=5005
configmask0=0xcf3f
configmask1=0x1f3f
configmask2=0x8700
configmask3=0x00e5
configmask4=0xc00f
configmask5=0xe00f
configmask6=0x400f
cp_mask=4,0x400f
cp_all=0x0000
cp_none=0x400f
cpd_mask=4,0x8000
cpd_on=0x0000
cpd_off=0x8000
Reading of the otherwise programmed PIC18F4550 works perfectly, but it
is not possible neither to erase the chip, nor to program it.
The programmer hardware (simple LPT based with 74LS07 buffers and single
PNP transistor) works perfectly with WinPic under M$ Windows.
Is there any significant difference between eg. 18F452 and 18F4550
regarding the programming procedure???
