Hi everyone,
Hi i'm a kind of stuck here,
I'm trying to figure out how a can get the dutycycle in % on my LCD, so that i have an indication on witch intensitie my LEDs are burning.
I have treid everything but i cant get it to work. I have treid i flowcode file from a topic (duty cycle.fcf) the concept is there but i cant figure it out how im going to implement this in to my project.
I hope you guys can help me out.
O one more thing, How can i use the output signal of de PWM do i need to select a port or is this a standard one on the PIC (16F877A).
Regards Jordy Kleian

Re: Display PWM DutyCycle on a LCD
Found the solution:
Load value of LDR into (LDR)
Calculation: (a = (LDR/2.55))
PWM Set DutyCycle = LDR
Display Number on LCD = a(%)
but the question now is how can i use the pwm signal for an output???
Can you help me please.

Not sure what you mean?Jordy101091 wrote:

If your asking what pins PWM o/p appear on, then answer is PWM1 o/p appears on pin 17 (CCP1).
PWM2 o/p appears on pin 16 (CCP2).
If you want further assistance, e.g how to set up flowchart so correct PWM appears on the o/p, depending on light LDR receives etc. Then I would recommend you post in correct topic area.
For Flowcode V4 in Flowcode V4 topic area. You need to register for that section first.
See here:

Or for Flowcode V3 in the Flowcode V3 topic. area etc.
What version of Flowcode have you got?

Re: Display PWM DutyCycle on a LCD
I have Flowcode v4 Student/Home version.
And thank you for answering my question.
I have taking a look in the PIC16F877A datasheet and there it is, my answer.
Thank you,
