Instant Interrupts - Revisited

[Darrel Taylor]

OK, So once you try that, you'll realize that the RAMP is not linear.

It's more a function of the LED output than the PWM routine itself.

Changing it to 10-bit, and creating a lookup table that matches the LED brightness, seems to work. But I'm sure someone can come up with a better idea.

Darrel, if all goes well I hope to be able to commercialize this project within the next 57 years. Can I have your permission to include all this nice stuff within my code?

Hey, when I first started this project it was supposed to be nothing but a few switches and LEDs. That must have been over 2 years ago. Now I'm using a 320x240 graphic LCD, an 18F4550, two 16F628, 2 MCP23016, surface mount components, USB full speed, VB and eventually an Access database (I'm Tim The Toolman Taylor of home electronics).

Having to learn electronics kinda put me slightly behind schedule.

Hi Tim

If you do it in the next 57 days (or 5.7), you can still use everything to your hearts content.

Of course, you could add some routines to the pot.

Help keep the Internet Free!

Thank you, thank you, thank you, thank you, thank you!
Thank you, thank you, thank you, thank you, thank you!

You can be sure that I will post anything useful that I can contribute; like the stuff for the SED1335 graphic LCD. Last time I Googled, there were no code examples for that one.

But I'm afraid there's not much I can add; you, Mister E and the other regulars have already covered anything I could conjure (and then some).

Well, I'm no philosophy major, but I figure...

The Day you decide you Can't, is also the Day you won't.

Give it a try.
Added: or should I say more tries (examples). (SED1335 320x240 graphic LCD)

Oh, and, You're Welcome, You're Welcome, You're Welcome,
You're Welcome, You're Welcome, You're Welcome.

Darrel,

I'm trying to work your Instant Interrupts in to my regular code.

When compiling, I get the following error messages:

WARNING:Unable to fit variable RetAddrH in requested bank 16
WARNING:Unable to fit variable RetAddrL in requested bank 16
WARNING:Unable to fit variable INT_Flags in requested bank 16
WARNING:Unable to fit variable HP_Vars in requested bank 0


Since these are just warnings, do I need to be concerned?
Is there a solution?

I'm the proud owner of an interupt routine in a PIC 16F628, my very first. It handles USART RX from a PIC 18F4550 wonderfully.

As mentionned on Darrel's information, I had to switch from MP to MPASM and encountered some delays in setting up the _CONFIG switches properly. But once I got that cleaned up I was up and running, this is just awesome!

(Charles, any chance you are using MP?)
