Try updating your AGWPE program.  This sounds like a typical message

Play a wave file .....test the error message first don't go to replicate the
problem by re-installing AGWPE

If you don't have caps on, I'd be very surprised if it wasn't oscillating. 
Linear voltage regulators are high gain amplifiers with feedback.

Howdy,

Having problems getting the PIC to clean reset.

I have MCLR enabled and held high with a 10k resistor. I sink it to gnd
using a button.

Ideas ? Seems to lock up and not reset well

1: not much pullup, 4.7k would be safer, or even 1k.
2: contact bounce. Add a 0.1uF cap across the switch, located at the micro.
3: EMI/ESD pickup on the wire, add 100-1kohm in series with the lead to the switch.

Hi,

I am not sure what you mean by a "clean reset" as opposed to perhaps a "non-clean reset".

If you mean that all file registers are reset to 0x00, I think a power down is required ( for perhaps a few seconds) will be required.

Resetting it with MCLR, will obviouslt reset PC and probably most FSR's but not RAM.

I have never had a problem with resets and have now used 100's of PICs in about 40 designs that I have done.

Perhaps a 10uF Tantalum to ground will ensure that /MCLR stays low for sufficient time to reset properly.

Thanks Lee,

I am using an LCD.

I have to hold the MCLR down for one to two seconds to get the thing to 
clean reset, but does not all the time work.

Sometimes the LCD goes nuts. and the system does not restore properley .

I found out about the RAM staying put yesteday, and I am looking into if 
this is casuing me hassles.

Thanks !

Hi Rich,

Have to go to class now, but I think I understand your problem.  LCD's are tricky to reset & there was a error in the initial Hitachi data sheet.  They are temperature sensitive & if you don't get it right, then it will behave as if the CPU is not resetting.  Been there done that. Get back to you.

Lee,

My name is Andrew.

The LCD is fine and happy to a power up. You can sit there all day and turn 
the whole cct on and off.

But when you just reset the PIC it does not always come back the same as a 
power cycle.

Andrew,
Read the PIC specs on reset: I kind of remember seeing some "nasty" 
details, like timing, or speed of signal change on the reset pin.
Don't remember now, but I remember thinking it was not as 
straightforward as most other micros.
PIC data sheets can be found on the web. Got them through Google search.
Wish I had time to go back search for you, but I'm in a hurry....

There is a microchip app note somewhere on this.

I (think) Dave implied a cap across the reset pin, which if not, do that. About 
0.01uf or so from MCLR to ground. Then the 10K pullup. 

Also, make sure the PUT is enabled.

Subject: [picsig] Slight OT: Ham Radio Repeater Locator
In-Reply-To: <BAY15-F34vrQk9wANDf0006639f@hotmail.com>
Message-ID: <BD2B3754.301D%VE3STI@rac.ca>

There is an interesting article in the August 2004 issue (Issue #169) of
Circuit Cellar by Glen Worstell, KG0T, called 'Ham Radio Repeater Locator.
It is a description of a device he constructed (using a Zilog Z8F6401, not a
PIC, so I'm a bit off topic!) that will determine and display the eight
nearest repeaters from its built-in database when connected to a GPS. It
will also tune your rig to these stations. He uses it while travelling
around the US. 

Unfortunately, I don't think you can access the article online without a
subscription. I bet the quite a few people on this list subscribe to the
print or electronic version of CC. However, if you see the magazine on a
newsstand, take a peek at it - it may be worth buying.

The code for the project (but not the article or schematic) can be
downloaded from:

ftp://ftp.circuitcellar.com/pub/Circuit_Cellar/2004/169/

Anyway, the article is interesting enough that I thought I would alert
people on the list.

Cute! I grok Z8, at least a while ago I did. 
I might port this to an AVR, and my TM-V7A.
