Hi all,
I use the 16F628 (nice chip..) but I seem to overlook something.
timer 1 and 2 have a TMRON bit, controlling whether the timer
runs or not.
Big Q : How do I stop/start TMR0 ?
if there is no smart way I will assign the timer to RB4/INT temporarily,
and have that fixe to Vcc or Vss but I would rather like to save
INT for some future expansion of my project.
please enlighten me !

RSP-PCI-KAA Robert S Paolucci added 'Questions:
Hi all,
I'm new to this list and to PIC programming. I recently bought an ICD from Omilex for the PIC16F877. Hooked it up and all has been working fine for about a month. Went to bed last night, everything was fine. Woke up this morning and tried to step thru a program and I now receive the "error performing requested operation" message. I looked through some posts here about the issue and tried all of the following for the entire day:
* made sure the "set debug mode" box was checked.
* saw a post that said uncheck the debug box, go in to simulator mode, then go back and check the box...no luck.
* NOP is first instruction
* using CCSPICC with ICD=TRUE on the device line.
* Tried different xtals (a few 4mHz and 20mHz ones)
* made sure the xtal fuse settings were correct.
* pulled my hair out (twice)
Can't step or run without getting the error. If I do a Self test it reports that the debug module does not exist. I can program in non-debug mode and the program works that way so the chip works (I also went out and bought a new chip and that does the same thing). Also, if it ever does allow me to step, it jumps to some unknown high address and all the registers get loaded with hex 47.
Voltages are 4.85 and 12.89
This seems to be a common problem and I can't figure out what, if anything, I am doing wrong. Could the voltages be wrong, the Olimex ICD, XTAL, fuses, sun spots? HEEELLLLLPPPPP!!!!

I am building a project that needs to run at -40c and off a battery/solar cell.
Either seems to be easy... both difficult. The problem I run into is a crystal
draws ~10ma (I'm shooting for the circuit to draw <1ma while idle/asleep) and
a ceramic resonator does not want to start up when cold. I found one solution
for the 16F876; put the PIC into reset for a sleep mode. It drew about 500ua. I
ran out of program space and went to an 18F252 (pin compatible with circuit) but
it draws ~900ua in the same condition. Is there any way to keep the resonator
running while the pic is in 'SLEEP'? Please send any ideas or help.

AFW-CentSys-M54 Anthony F Williams added 'Questions:
Hi,
I'm fiddling with CCS C compiler to see if I like it and want to know why when I try to run my PIC ICD does it start to execute the code at Program Counter 0x02. This is as seen in the program watch window after a "reset" - always.
This is a real nuisance 'cos the two preceding lines "movlw 0x00 & movwf 0x0A" are skipped and they are needed to set the page control PCLATH to zero. Hence the goto line for "void main ()" in PC 0x02 actually gets added to 0x1800 (which is page 3), and therefore of course my code cannot run without lengthy and painful work arounds.
Anyone out there kknow what I'm doing wrong & how I can get past this hassle?
