Hi gaugeguy,

How do you do that in code when I call read RTC it goes to built in I2C functions that does not return if hung.

void ds1307_get_date(BYTE &day, BYTE &mth, BYTE &ye ...

Thanks for all the great answers.

Using Pic 18F27K40, CCS PCH C Compiler, Version 5.078.

Can the I2C Bus scanner code from the code library clobber the time/date in a DS1307 RTC Module that are available from many web sites.

OK.

First change the clock to:

#use delay(CRYSTAL=10MHz, CLOCK=40MHz)

This ensures the compiler knows how the PLL needs to be configured.

But your real problem is hardware. Generally newer ...

Hi All,

Thanks for the fuses.txt file info. Exclamation

Hi All,

I think I am going to give up. Math errors everywhere.

Tried simplifing calculations then got to Sin() and Cos() functions.
all answers appeared wrong based on calculator.

Strange I ...

Thanks Ttelmah,

Got it compiled found lots of calculation errors with complex equations.

Trying to make equations less complex.

Still working on it.
Very Happy

Hi

Thank you in advance for any help.
