Re: Can't print floats??

Thank you. I found an old version I had from 2013, and realised that I had already changed it then to print floats and it works fine.

Can't print floats??

I am working on the Jaycar water flow gauge. I note the section // Because we want to output a // floating point value and print() can't handle floats we have to do some trickery // to output the whole number part, then a decimal point, then the fractional part. unsigned int frac; // Print the flow ...

Re: Pachube/Cosm Alternatives

There has been discussion on this non the Arduino Forum. Govestreams is worth a look.

Stuff about millis roll-over here

I am using the Jaycar water flow meter. It appears that the counting method leaves a bit to be desired.

Gawd... so THAT's where it was...

I thought Eagles were just PCB layouts.

Re: Ethernet diagnosis help

Amongst all that writing and pictures, I couldn't find a circuit, so I submit this for approval by those who would prefer to see one.

Re: Ethernet diagnosis help

It's a straightforward res/cap timer. The top connection is to the 5v rail. I think the circuit is for a bare bones Atmel, rather than an Arduino board and it looks too good to be true. It does say it is a hardware reset but is it good to do everything? The 555 device mentioned before is also a res/...

Re: Ethernet diagnosis help

The hardware reset which i will probably try (in addition to the single wire solution) is http://www.playwitharduino.com/?p=291&lang=en, but that also wont catch hung code.... Plenty of challenges. Feel free to PM me if you want to bounce around other ideas Thank you. I understand there are two sce...

Hi ngp99, When summing numbers they will eventually exceed the limit of the variable....and when millis() roles over and re-zeros I didnt want to find out the hard way 40 days in that my logic was flawed in dealing with the rollover....Hence resetting once a day means that any logic errors will be ...

Re: Ethernet diagnosis help

I'm struggling to see why you need a watchdog, but I had never heard of the term until a couple of days ago and it may not be a bad precaution. Now that the code is posted, I recognise the goal but I don't understand the method, i.e. the code for transmission to cosm. Cosm underwent something of a p...
