MikroC 7.3.0 Beta

[genesis614]

Hello!

I have tested the MikroC 7.3.0 Beta version and it seems to me that my problem with PIC18F47K42 is still the same as before with the 7.2.0 version.
I have my code down below which i used as an example code.
I have less knowledge about PIC18F47K42 and as what I have observed the MCU is fluctuating or rebooting every second. The GLCD
flickers and the program will restart. I monitored with a PicoScope and the output pins are fluctuating to zero then back to normal.
I am using EasyPicV7 HW Rev. 1.03.

The program is working fine when i used a PIC16F887 and with the sample code a little bit modified to run the MCU. There were no fluctuations.
Can somebody please tell me if it is a hardware issue or a coding issue? Does anybody tried the beta version and found to be working perfectly now?

I can not point where to start trouble shooting.

Thanks!

Hi,

There's special forum for discussing beta versions: mikroC PRO for PIC Beta Testing.

Does anybody tried the beta version and found to be working perfectly now?

Wouldn't use the word 'perfectly' , but the main obstacles have been removed (partly by brute force, i.e. separate libraries for K42 and K83 processors). I have successfully run a GLCD project, though based on my own GLCD library.

As for your code, starting with the usual suspects - did you switch off the watchdog in Edit Project (it's on by default)?

[genesis614]

Thanks Janni!

I did not know the WDT is ON by default.
That is why it keeps on resetting. It is working now.
I also have to check my Oscillator because it is running slow.
I have a 16Mhz Crystal connected to my MCU but the the output is slow.
It is like i have set a 1 second delay but the actual delay is more than 4 seconds.
I have a snap shot below of the MCU General Config Settings.

Well, it depends on what mE developers decide to do in definition files. Apparently nobody had time to prepare safe settings.
You should also clear the Multi-Vector interrupt enable bit - at the moment it seems to have no effect on compiler but it will have effect on processor if you try to use interrupts.

That's possible - you have the Fail-Safe Clock Monitor enabled, which means that processor may operate on default 4MHz internal clock.
