MSP430F Dim and Bright for LED

This is typically done by programming a timer to output a PWM signal.

Thanks for the reply.
where i can get the sample source code for " timer to output a PWM signal".

In the "MSP430F532x Code Examples" package, which you find on the MSP430F5328 page. One PWM example would be ta0_17.c

Hi Clemens,

Thank you so much. I am able to dim the LED based on example code.

I have to set PWM frequency to 900 Hz. Could you please help to calculate the PWM frequency.

Hi,
I have calculated the same but when i am checking on that pin 14Khz frequency it's showing.
I have configured as below:

P1DIR |= BIT2; // P1.2 output
P1SEL |= BIT2; // P1.2 options select
TA0CCR0 = 1111-1; // PWM Period
TA0CCTL1 = OUTMOD_7; // CCR1 reset/set
TA0CCR1 = 555; // CCR1 PWM duty cycle
TA0CTL = TASSEL_1 + MC_1 + TACLR; // ACLK, up mode, clear TAR

Am i doing anything wrong?

Sorry Actually I am using SMCLK not ACLK as below:

TA0CTL = TASSEL_2 + MC_1 + TACLR; // SMCLK, up mode, clear TAR

Hi,

Sorry I haven't seen i was external crystal of 16MHz.

I am able to set 900Hz successfully.

Thank you so much :)
