Controlling RGB LED strip with MSP430?

Recommended Posts

I believe the answer to my questions above is explained here: https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/94929


In this thread a TI employee explains that the quotation from @@terjeio does not specify maximum output current in the sense that higher current would be damaging.  It specifies the maximum current to hold a specified voltage drop. This is because The MSP430 is a push/pull CMOS type and sourcing current will result in a voltage drop.   In the case of the table and footnote quoted by @@terjeio there is a specified voltage drop of  Vcc - 0.3V.  If you can tolerate additional voltage drop from the port / pin then the microcontroller can supply more current as shown in the graphs on page 25.


I think the resistors at the pins could stand to be larger but are OK.

I got my RGB strip in today and it is running without a problem on a MSP-EXP430G2.  I am powering a single strip with a 12V, 5A source.   I used the Adafruit sketch and circuit modified as described in my post above dated 26 June 2015 - 09:40 PM.  Now to cut it up and reconfigure it into the shapes and pieces I need...
