Help me with dimming ballast using MSP430FG4618

[sumansingh]

hello every one.....
i am new to dis controllers so plz help me........

actually my application is dimming ballast n iam using here msp430.but in my application i want generate 0-10V to dimm the ballast which means if it is 0V...0% dimm...n if it is 5V...50%..like dat up to 10V....ok so plz tell me any idea about dis........ my thought is by using PWM n ADC i can generate dis 10V r OPTPISOLATER TRAIC DRIVER is better.........plz i dnt knw how to do dis project plz help me.....................

Hi

Depand on type of MSP430 used you can use PWM output filter it and amplify it using an opamp

Whether you have D/A on the micro(MSP430F16xx) just set the A/D and add and amplifier to bring the voltage output to the right level

All the best

tnx 4 replying bobi,

here iam using msp430fg4618...so it having DAC...but iam nt using pwm method i wnt to use dac and op-amp...and my voltages are automatically generate....so iam confuse here to how to generate these voltage values
