| 18F46K80 using NOMCLR instruction Programed one time |

Hi,
One time each (2) chip's ID as good and programed,
Just ordered more 16F46K80,
Digi-Key now has stock in house,
as what have is dead in the water until problem is resolved,
the compiler needs update for #FUSE, # INT and
new programer software for the U-64 or new model if needed.
SEE POST BY "gaugeguy" near end of this postings on problem not new.
Time is too short for waiting on CCS.
Found that the instruction NOMCLR to change the master reset pin to a
input pin RE3 then may be the problem, CCs will have to change the way to return the master reset to operation.
Each chip I have is programmed once with a test pgm,
can not reprogram chip again at this time.
Looks as the U-64 or a new model will be needed to program the new chip?
U-40 will not do it.

The compiler certainly supports it, at least in a basic sense, because the
following program compiles with no errors with vs. 4.119 in MPLAB.
| Code: |
#include <18F46K80.h>
#fuses HSH, NOWDT
#use delay(clock=20M)
//======================
void main(void)
{
while(1);
}

You mean that CCSLOAD or maybe the IDE don't support that PIC yet. |

Guess will have to wait on CCS as this chip is not supported yet.
Have 2 units ready today but no compiler yet for the chip,
FAILURE: "NOT YET SUPPORTED" is the message from programmer.
more to follow as have just sent note to CCS about the problem.

Hi PCM,
Yes compiler is good but programmer shows unsupported chip when trying to program a chip.
See my earler post of a test program, that compiles fine.
ccsload with U40,

Hi,
CCS got back on the issue, requested to upgrade programmer firmware.
U-40 on this machine for 2.88 a no go on update,
so,
I went to my other computer
That has a U-64 on that one,
it request for the firmware to be upgraded to 2.88, did the upgrade
of firmware to 2.88.
Still error as being unsupported CHIP.
There is a issue with U-40,
may not be usable on the new chips? as would not upgrade to 2.88.
At this time have the info to CCS, so wait for them to resolve the issue.

I had a problem on all the 18F45Kxx and 18F46Kxx using the U40. Had to
scrap the U40 and go to the U64. The U64 works with no problems.

On the chips you chat about are those the dual voltage chips also?
The 18F46K80 has a built in 3.3 regulator for the new core being use.
The A4 pin was taken over for that regulator pin to the outside world,
must add a 10 UF LOW ESR cap on that pin.
The chip supply is the normal old +5 volts just same as the18F4680 series of chips.
Believe this maybe the problem for CCS,
as their drawers are on the floor about the dual voltage thing,
that is the reason the U-64 will - maybe work??
it is adjustable to voltages down to 1.8v I believe??
U-40 is fixed voltage I believe, may be wrong on that??
Thinking of sending them a set of suspenders, so their drawers can be off the floor and they can fix the issue?

The K80 series chips have a different sequence to get into programming mode than the other 'K' chips and I don't think CCS has been able to get it working yet. Low voltage programming requires a code to be sent serially on many chips, but the K80 requires it for both low voltage and high voltage programming entry.
Hopefully they get if figured out soon. |
