555 timer?!

[Exodeos]

I'd really like to be able to program the chip using a 3.5 mm jack or something similar so that I don't have to re-open the controller to re flash it. Is this possible? I read something about a picaxe chip being able to do this? would I need to use different code/ setup? thanks for all this help!

Its basically impossible to reflash a pic and idk about a 555, matt, howmany free samples can u get?

Here is an idea, do so research find a MC that can be used through an USB port!!!!! What is that word I'm looking for??????........__________ Oh yeah, READ THE DAMN DATA-SHEETS........

dude I am sorry to say this, but you need to stop trying to help people and learn a small bit about what your talking about. I have been nice, but now you just sound like a dumb butt.

you can reflash any MC insert it into a programer, open hex file and click program, the programer will first erase the PIC and reprogram it with the new hex file loaded into your programer.

It sounds like you want to preform incircut programing, as fredrow said do some research, find a pic that suits your needs and write a program for it. YES picaxe is capable if ICP, but then again so are most MC's today.

the 555 timer CANNOT be programed. it is a timer. do the research. didnt I provide you the data sheet? if not look it up. in lamans terms the 555 is a light switch that continuously keeps flipping up and down, or on and off. if you add an outside factor to the light switch (say tape a penny to it) it will create resistance and the switch wont flip as fast, this is what the resistors and capasitors are used for when using timers.

thank you Matt, I was aware that the 555 timer could not be programmed, but the clarification on the icp proved quite helpfull. @ fredrow, I understand how annoying it gets with people not reading the blatantly obvious information available on this site, and others, as was the case with the data sheets. However I am sixteen and only just getting into this type of thing at all and it had not occurred to me at all to read them for that information. So to Matt for not doing my own research before asking, I am sorry. So thank you for pointing me where to get the information. I have decided to go with hazers original plan with the programmer design that you provided. I have built the programmer and my chips should arrive soon. At some point I may try to accomplish the icp however that is way above my head at this point as I can not write code. To anyone reading this (in my opinion) buying a viking chip is a better option than what I have done as I could have purchased a diy kit from here and been done by now for probably cheaper with a better rapidfire chip that could do more. That being said I do get to have some self satisfaction from doing this.

@ thejld thanks for trying to help but please do some research or do not respond if your not 100 percent sure of what your talking about as had I not read that 555 timers could not be flashed on another site before that it would have been confusing.

heres a curve ball for you. if your going ot use hazers code, use the tut I gave you to get your barings on programing, then use this tut and code instead of the burnme up code. it is called flex, and is a much better RF system. (unless you want a sleeper mod)
