FreescaleTM MC9S12NE64 / Re: Can I use uTasker?

Hi, my IP relay project is almost completed, it's in a rack enclosure, has 6 resettable fused IEC outlets leaving 2 relays for "something else" just need to bring the relay leds to the front panel. But it is otherwise working and does the job.
The NE64 board I purchased is preprogrammed. I was looking into making my own firmware for it but the limitations you have found and I have been advised of made me reconsider. I'm not experienced in this field and this would have been the first chip I wrote code for. That in mind I'm looking to "upgrade" what I have to the newer version chip once I get my head round it.

I want for more functions then is currently available out of the box on the NE64 so I will invest my time in newer technology. The developer of the board I have has given me a PHP script to talk to the NE64 via SNMP traps which alow relay switching and reading of the unused 8 inputs. This would mean I can add the functionality I desire with programming using skills I already have, but then it is not an embedded device as such since the additional features rely on an external webserver.

I'm more interested in environmental controls at the moment, but the delayed startup idea for inductive loads is a good idea. I too want to bounce my modem/router if it can't ping the outside world. max number of restarts in case the router isn't at fault I don't want it restarting all the time until I can attend it.
I wanted a web programmable interface so the user can set events, if input X > 1.2 switch relay X off etc. I want to add buttons on the front, if held in for a say 3 secs cycle the applicable relay off then on to restart connected load, if a momentary press toggle the relay state.

I don't intend on selling this as a product, It's just something to work on to combine my IT skills with my electrical skills to gain a better understanding of electronics, specifically embedded devices.

Good luck with your implementation!

That isn't much of an investment to enter the current arena. I enjoy electronics, work in IT so enjoy computing and currently program for the web. This seems to fit nice. I just don't know where to start. Could you point me in the right direction for some further reading?

As a start I would like to make a web accessable enviromental monitoring unit. say some device to monitor temp and then switching of fans with an lcd output as well as the web based. This should be simple enough electronically but something to work toward for an application. Then as I begin to understand what these things can really do I can work on something far more powerful.

EDIT: just learnt the demo board comes as a HVAC system! lol

I totally see your point! And this causes me a problem. See I have now already purchased a NE64 board that will as is solve my problem. Would it be of no benefit at all to learn the basics on this chip and then decide if this is really a route I want to invest more time (and money) into?

I'm a beginner at electronics, no previous PIC experience other than building kits, and loading precompiled hex files. I can manufacture my own boards and have designed some analogue circuits. Anyway I was looking for a TCP/IP accessible computer PDU to remotely reboot connected servers etc. Prebuilt PDU's are way to expensive so I purchased to switch the outlets.

I was researching into changing the web GUI so it was branded, not necessary but I like to tinker and eventually landed here. The picture looks like it has a MC9S12NE64 chip but I'm concerned about flashing it as the documentation I have read kind of refers to the Demo board which seems much more comprehensive then what I have (or will have when it arrives) I have 8 outputs and inputs that will not be used at present so I intend to use them for a steep learning curve, maybe some kind of environmental monitoring.

It seems like if I was to flash it and it was no longer functioning I can factory reset, will this be true after I flash with my own cooked up firmware? or is it just to reset default settings?

Will I have enough EEPROM for uTasker, I think the Demo board has much more available resources.

I often jump into the deep end so I'm not phased by the complexity unless one inevitable mistake will render this board a veg.

I noticed a firmware upload on the current web menu, would this suggest uTasker is already in use?

Is it time to simulate/learn or is it a dead end already?

Thanks in advance!
