HH2 Option 1 source code

[6666]

Hooray it works
I took Altra's ASM code and compiled it to a hex file in MPLAB v8.76
with no errors reported.

Then I burnt the pic chip using a JDM programmer (burner)
and the Win pic880 v3.64f software, no errors reported

and connected a variable resistor (10K) between the Vcc and Vdd with the wiper connected to pin 7 on the pic chip.

And blow me down, it seems to have worked.

Here are some wave forms from the Tx pin 6, and sample pins 2/3. and the delay between them.

Here is the pulse on pin 6

[6666]

Here is the pulse on pin 2 and the same on pin 3, they look the same

very short pulse.

[6666]

This shows pin 6 the tx pulse pin at the top of screen, compared to pin 3 the first sample pin, with pot at minimum delay.

[6666]

This shows pin 6 and pin 3 with pot at half way, thats half the maximum delay.

[6666]

Maximum delay, you will see the pulse has moved by 3 cm's

[6666]

Pin 2 sample 2, pot set to minimum delay

[6666]

Pin 2 sample 2, pot set to maximum delay

Nice !!

Thanks for the info , great if there is succes !

6666,

Good that you got it working. I reversed sample 1 and 2 in software to give
me a positive response on the output of the threshold amp. If you are using
Carl's original HH2 circuit then use my code which JLK modified.

Regards
Mark

Hi Altra
thanks for your code
yours is the only code that I have been able to make work

not sure if I have a couple of dud pic chips,
I burnt the JLK code but the pic is dead,
got to retry the other JLK code in new pic chip.

Does anybody have a hex file from Carls source code ?

and could anybody please tell me what version of MPLAB
was in use in Nov 2009 when Carl was experimenting with this?
thanks

[6666]

Had a little win today
I have figured out what version of mplab was in use in 2009, seems it was Ver 8.00
anyhow have installed it and run carls asm code through the compiler
and this hex code popped out with no reported errors
I have yet to burn a pic and see if it works
stay tuned

The chip took the hex file ok
just got to test it.

Hello 6666

That's great work from you !! So removeing the newer Mplab version and replace it for the older version 8.00, than you can load Carls C code and compile it to a hex ?

Thanks for this update !

Best regards.

Hi Ap

its alive, it works

I can see pulses from carl's code
will post pictures asap.
