MSP430G2312 won't work standalone


Recommended Posts

I wouldn't know why not. A small resistor calculation would give:

3v3/47k = 70uA even if the launchpad would have a resistor on this pin elready, the accumulated current would be about 140uA. There is no problem for the MSP to drive such a pin (I say this, because the programmer part of the launchpad is another MSP430).

Heh, never thought about pulling TEST to GND.  Wonder if that's what kept screwing me up last month... (was doing a standalone WS2811 driving board and it was acting very bizarre, never figured it out)

 

edit:

Actually the datasheet (G2x53, G2x13 datasheet I'm looking at) mentions there is an internal pull-down on the TEST line.

 

Rinternal - Internal pulldown resistance on TEST ... MIN 25, TYP 50, MAX 90 (units kOhms)

Maybe that's just not sufficient?
