DSPIC30F4012 v230 Source Code

Would anybody have a picture of the input signal that goes to pin 5 which is the ADC input ?

thanks

The "No target" voltage to the ADC input can be anywhwere from 0 to 5 volts ... however somewhere between 1 and 4 volts gives you some headroom for the signal to move up or down ( if descrim is required then the voltage might move up for ferrous and down for non ferrous ).

The input voltage to the ADC must already have been filtered and ground balanced.

Hi 6666, I haven't got that far yet but I do remember some info in another thread. I would be guessing 2.5 volts as 0 because from memory the display shows +/-2.5

Thanks Mick
have copied the info on the linked page
I have 4 4012's programmed now
there is some problem with the ISCP adapter I bought
the simple rs232 works 100% when you try to reprogram
I have written to the manufacture
cheers

The analogue IN can accept a voltage from 0 to 5 volts and is approximately 17 bit accurate ( yes 17 real bits ..... ) The analogue input expects to see a signal that consists of a relatively stable base voltage that varies as targets are passed over ... so it is a motion detector.

Finally some success in REPROGRAMMING these 4012's

Thank you for reply,my work is wrong i must begin again,i'll tell you,can you tell me the characteristic of FS18G,best regards.

I would be guessing the spelling is wrong, but if you change it to SF18G you'll find a result in google.

EDIT I'm just using 1N4007 at the moment

Hi All
got myself a AUTHENTIC Microchip™ PICkit™ 2 USB Programmer. Part # PG164120

will see what happens now with these 4012's

[6666]

Andrew is this what you are looking for ?
and I think you have to use the pickit2 software to use UART function

Found it

If you are only burning the hex files and want to use the inbuilt UART tool ( serial comms ) to talk to the UNIP chip ( saves wiring up an LCD ) get the pickit software here ....

Hi Mick
Moodz it's so busy than i ask you some help;i had got a pickit 2 clone for programing the 30F4011 and 12 but i can't,it's the first time and can you explain me how obtain in the uart tool:Moodz UNIPI v2.30,E,R,X,A,B,C,etc,,,may i write this?I can't enter the hex file of Metal23zip;Thank you for read this,best regards.Andrew.

Hi Mick and Moodz
this is chip number 2 with nice pulses

6666

Looks good. Now it's time to get the LCD working.

Success

received my chips back from Mick today
and have tested one of them
and can see some pulses at last
THANKS MICK

[6666]

Hi Mick
thank you
I need to work out what the bug is in my system with the pickit3

cheers

Hi 6666, both PIC's are fixed and I have sent you a PM.



Cheers
