MSP430 based 32 LED driver

Posted on Thursday, April 12th, 2012 in MSP430 by DP

Parker designed a MSP430 based 32 LED driver. His intends to use it as a VU meter, by reading a ADC line with the uC and turning LEDs on and of depending on the calculated VU level.

Finished the VU. Changed the name to a 32 LED Driver as that is what it really is. The idea for the VU is to sample the sense line via an ADC a couple times and average the value. Then the MSP430 will look up that value on a table and light up that many LEDs. Should be fairly straight forward.
