THANK YOU.
Flowcode Attachment was created with flowcode 4.
This would be useful if you are already using both PWM components in Flowcode, and would like to set-up the third
If you are using 1 or more PWM channels with Flowcode then Both t2con and pr2 are not required.
Instructions: Just enter clock frequency , PWM frequency and Duty.
On flowchart Place a 0 output for each CCP in use. e.g if CCP3 is RB5, then use an output icon with B5 set at 0
Select prescaler to give highest Pr2.
Copy and paste cells containing required values into a flowcode C box after output icon e.g.
t2con = 0b0000101 ;
pr2 = 0b11111001 ;
ccpr1l = 0b01111101 ;
ccp1con = 0b00001100 ;
I have protected excel sheet to avoid entering data into wrong cells. There is no password if you would like to see how values are calculated.

Note example is using fosc=4MHz, fpwm=1KHz & Duty=50%
The code for pasting into C box will automatically change as you alter PWM frequencies, prescaler etc., removing all the hard work and saving time.
Also note that with older versions of excel (pre 2007 i believe), analysis toolpak will have to be added.
