One small step closer
my encoder switches have arrived

Thanks Moodz

thanks

If moodz is too busy I'll be able to check and reprogram them for you ok.



Mick

I am happy for Mick to do it ... thanks Mick ...I am still fiddling with the amplifier ... there is plenty of signal ... but plenty of drift as well ... if I get rid of the drift ... the signal goes with it .

Hi Mick
thats great thanks

No worries. If you want me to do it, PM me to say so and I'll PM back the address.

Hi Mick
thats great thanks

I think I have come to the conclusion that my pickit3 clone setup
is not programming my chips properly. I have 4 chips.



today i decided to try and re program a couple of them
first i tried to erase them, which seemed to work.

but when i tried the blank check or reprogram them or verify
i started getting errors, maybe the chips are duds.


trying to erase them, and program them now just gives errors.


I dont like to ask for help, but before i give up, Mr Moodz would you mind if I posted a couple of chips to you
to see if your system can erase the chips and reprogram them please ?

I know that this is not your intention to support folks that have problems like this
but if your pickit2 system works with my chips then it will prove a fault in my system,
then I may buy a real pickit2 and try again.

If you dont want to do this, thats ok, I may have another try at this project later.

Hi Mick

Have you got the 22pf ceramic caps installed on the crystal pin9 to gnd and pin10 to gnd.

yes just like the drawing a few posts back


Hi Moodz

If you are relying on the Pickit to supply the +5 it probably will not work

I am using a simple external supply, should have enough current
moodz how much current does your chip draw ?


I have tested the xtal its purring at 10mhz
I have started a vero board pcb , it should be running already
but will see what happens,

btw for testing the lcd it needs a 5k - 10k pot for the contrast control
turned almost to full earth for the display to work
or the characters are invisible
you will see here a row of blocks

[moodz]

I connected pins +4.8v 13,20,28 and Gnd 8,19,27 and R9 pin1 and R1 pin11, r2 pin 12 ,
R4 and 5 to pins 6,7, and the xtal to pins 9,10

it should work,

does it need the full 5v to work ?

i'll knock up a cct to test the xtal

If you are relying on the Pickit to supply the +5 it probably will not work ... the supply from the programmer is not clean enough ... thats what I found anyway.

Hi Moodz
the breadboard is just the plugin type
so only one side

I will knock up a vero board
that should be all soldered connections
and see what happens
this is such a simple project
it should be working by now

found some info on how to test the LCD
so will do that to , to check if its ok

edit good news the lcd tests ok

I should test the xtal to

Those CPUs have more than one ground and +5 volt supply pin ... make sure all are connected or it wont work.

tie the pushbutton input pins high to +5 also if just testing.

Moodz can I just check something with you
what should be on pin 12, (the old zero button)
should it have a 10k R on it or not
seeing the software is not looking for an earth to start it ?

[moodz]

I have programed my chip with H20111018.zip
I got the message program verify
so I assume the chip is ok
knocked up the cct on breadboard (with and without lcd), but at 4.8 volts
it only draws around 8 ma, and no pulses with or without lcd

the breadboard connections all seem firm and ok
not sure what to try next, maybe make a real pcb

Please post hi res photo of top and bottom of board and I will see what I can do for you.
