so i just figured out the problem,
I was using another voltage regulator (LM317) for another IC that was connected to an mbed GPIO.
This regulators, LM317 and 7805, when connected to the same GND as mbed seem to don't like each other because one of them (randomly who starts first) gets really really really hot, but without the mbed on the circuit they run OK!
So i figured that the regulators and the mbed just don't match....
Solution: drop the LM317 and let the mbed internal regulator do the job.
I'll post this project on cookbook page.
Thanks all for the support and feedback on this one.
OH! about the project...it went ok! (my colleague lend me his mbed ehe )
Hi everyone, ok i'll get to the poin on this one.
I've got a big presentation tomorrow on college and the main dish for the recipe is an mbed and a wifly module.
Yesterday everything was working fine, while readjusting the circuit on breadboard something happened and everything is down (even the wifly).
I don't know if this is an issue regarding power and voltage distribution but here's the circuit:
I don't know if my mbed is dead and wifly module too... I've connected a battery to a 7805 for constant voltage ...
Leave your opinion on the power supply (capacitors are there for spike protection).
Thanks for the support
