Hi Ben,
Sorry about this
I have the same issue with a PIC16F1786 device where the Timer 2 prescaler can only set up to 16 and not 64,in the PWM component
Please can you organize me a fix

Hi Ben.
Thank you for the PWM fix it is working Fine
Can you please help me understand (attached is the Flowchart) before adding the pwm component the Flowchart used 3.6% memory(298words)
adding the PWM component and use the Enable makro and the Set duty cycle makro pushed the memory to 52.3%
This is also the reason that my PIC1508 Ran out of memory,
Why is the PWM component using so much memory ?
Please can you compile the attached Flowchart and compare the memory use with and without the PWM component , it seams to me not correct tzat a single component use 50% of memory

Hi Peter,
For me when I compile the program as was (enable and set duty macro calls present in the program) I get this memory usage.
Memory Summary:
Program space used 157h ( 343) of 2000h words ( 4.2%)
Data space used 7Ah ( 122) of 400h bytes ( 11.9%)
EEPROM space used 0h ( 0) of 100h bytes ( 0.0%)
Data stack space used 0h ( 0) of 37Ch bytes ( 0.0%)
Configuration bits used 2h ( 2) of 2h words (100.0%)
ID Location space used 0h ( 0) of 4h bytes ( 0.0%)
I've tried the default compiler and also the latest XC8, both in Free mode and the stats are largely the same.
I take it you're using Flowcode 7.3. Did you do a complete installation or did you install the patch?

Hi Ben.
When I updated to 7.3 the page said that if you have 7.1 and higher you should only install the patch so I installed the patch,
I will do a uninstall now and do a new full installation
I am crazy with this stuff now

Hi Ben.
Thank you for your support,
I did a full install and now I get the same values of memory usage as you.(PWM enabled and Duty cycle set )
I can kick myself as I did what your update page information was and it caused me big issues
Many Thanks Ben that you compiled and gave me a reference
