strange behavior

[Florin T]

I have a small problem. After installing version v.0.95.007 I recompile with new compiler the source files. The receive files that do not behave properly. If sources are compile in V 0.94 04/02/2015 files obtained are accurate.I uninstalled all traces v.0.95.007 cleaned and reinstalled. It still does not work. A little help please .

Attach files: two files with the same content and files generated by the two compilers.

I have to ask what does not work?

I do not know what to look for. Compile error? LCD not working? sorry, we need more infomation.

And, may I strongly recommend we get you on the latest build as this has 100's of improvements over the older versions.

Port port C2 drive a transistor that is connected lcd screen. HPWM order 1, 40, 90 not determine the proper function PWM. The same file compiled with the older version works correctly

[Florin T]

does not matter what value put in HPWM 1, 40, 90 if compiled with the new version, the fill factor is not changed and is very small. With the old version correct results are obtained. I checked with oscilloscope

[Anobium]

Recommend we get you onto v0.95.010 code. PWM has been revised to provide better backwards compatibility support.

These issues are resolved in v0.95.010.

Fix 285 resolves this issue.
'#285 Fix pwm.h Fixed legacy PWM command. BIT tests were executing the incorrect ASM.

Testing shows that PWMON and HWPWM for this chip architecture is operating as expected. The screenshot below shows HPPWM on channel 1 and PWMON (using the defines) on channel two.

.

The code is changing the duty so the duty % is therefore correct.

The test program below was used. This is now part of the demo suite.
