12F675 and LM35 coding issue

[Bobbo_ZA]

Now there's an awesome idea, will work out a way to waterproof the LM35 out the bottom of the case.

Need to also work a way where you can press a button and the device will stay on for X number of minutes and then either sleep or turn off. Then she can press the button, drop it in and watch the colors, of course she will be taught that it is an "Authorized" bath time device, ;-)

BTW, last night I managed to read the input signal from my RC Transmitter (Ok, pulsin is not so hard) from 2 channels and drive 3 different items as follows:

1. LED for testing purposes - easy
2. Pass through for the servo control
3. Glow igniter (proportional depending on the throttle location as well as always on depending on the Gear channel switch) +-3A load - Running through a FET - I learn't how to use these in 1 night, :-) I'm quite chuffed to understand how these work now, it opens up a range of possibilities as now I can switch fairly high loads from the PIC.

Thanks Alain, I noticed you are on RC Groups as well, hope to bump into you there as well in the future, I'll begin posting my autopilot build there soon, planning to use PICs as fail safes for the main navigation / stabilization hardware, :-)

Hi, Bobbo

For the Glow-igniter, I've published an advanced one ... several years ago.

Article is written in French ( ... ! ) so, the question ...

Do you read French ??? ( even under torture ...)

Alain,

My French is nowhere near as good as your English, :-)

Thankfully, the internet has given us google translate which works quite well with french and where it stumbles I can normally work out the meaning when put into the correct context.

I've had a look around but am a bit confused around 2 things.

1. I'll need a jumper to allow the user to input "Programming mode" - Not sure where to put it, would GP3 with a pulldown res work or can I use any other GP?
2. Once I have read the value I can flash the LED a couple of times to show the user the chip has the reading, however, when the chip reboots, how do i store the value in memory that will not be reset on a power cycle, :-)

Easy to explain but quite complex principles to work out, :-) seems like i might be getting ahead of myself.

Hi, Bobbo

have a look to this program ...

It's not the glow driver ( you would be lost @ first lines ...) but a lighting system shown on RC Groups.
as processor is a 12F675 ... it will be easier.

But main pulse handling routines are in ...

Ok, wow, that code has some awesome information in it, going to be fun getting this to work.

You've also set a standard as to what my code should look like, :-) I was never very good at commenting when I did programming, am learning that its almost mandatory in the real world, :-).

Thanks a mil
