Lgbeno 189 Posted November 24, 2014 Share Posted November 24, 2014 I have not actually drawn this out or simulated it but I think that if you were to take 2 PMOS fets, put then source to source, comment in series with the battery, then connect the two gates, pull down to ground and connect to the power input, that might do the trick Quote Link to post Share on other sites
cde 334 Posted November 24, 2014 Share Posted November 24, 2014 Wait, have you tried swapping the msp430 for another one, as a sanity check? Quote Link to post Share on other sites
rebeltaz 36 Posted November 24, 2014 Author Share Posted November 24, 2014 I haven't tried replacing the MSP, but I will try that as well as the other suggestions this weekend. No time off until Thursday Thanks guys! I will keep y'all posted... Quote Link to post Share on other sites
rebeltaz 36 Posted November 30, 2014 Author Share Posted November 30, 2014 I just wanted to let everyone know, in case any one else runs into this, that I got this working. I removed R23 from the circuit, left D2 as a 1n4148 and replaced D1 with an unknown rectifier that I found in my junk box with a voltage drop of about .168v. I also modified the code to incorporate a power good line to disable scanning if the main power is lost. Works great! Thanks for all y'alls help! Quote Link to post Share on other sites
