SPWM_INT - Multiple Software PWM Question

[Darrel Taylor]

Those warnings aren't coming from the section you posted.

You are trying to use a value of 500 with byte sized EEPROM locations.

But I'm pretty sure you really want WORD sized EEPROM locations.
Change this ...

' ***************************************************************
' EEPROM Variables
' ***************************************************************

MotorRPM_Default   CON  500 ; half speed if max is 1000
EE_MotorRPM        DATA MotorRPM_Default
MotorRPM           VAR  BYTE
READ EE_MotorRPM, MotorRPM

PortEngDir_Default CON  0
EE_PortEngDir      DATA PortEngDir_Default
PortEngDir         VAR  BYTE
READ EE_PortEngDir, PortEngDir

... to this ...

' ***************************************************************
' EEPROM Variables
' ***************************************************************

MotorRPM_Default   CON  500 ; half speed if max is 1000
EE_MotorRPM        DATA WORD MotorRPM_Default
MotorRPM           VAR  WORD
READ EE_MotorRPM, WORD MotorRPM

PortEngDir_Default CON  0
EE_PortEngDir      DATA WORD PortEngDir_Default
PortEngDir         VAR  WORD
READ EE_PortEngDir, WORD PortEngDir

There are a few other WRITE statements in your program that need to be changed too.

You're a life saver, Darrel - thanks. Updated the corresponding WRITE statements and all compiles fine (I didn't change the 'PortEngDir' stuff as that has only 2 values: 0 & 1)

Was there anything in the warning message which told you where to look?'

[Darrel Taylor]

Woops, I changed too much.

When I can't tell were an error is comming from, I go to the .LST file and search for the error or warning.
Ususally, the first error found in that file is the most important one.

It helps being able to read assembly language though.

[RossWaddell]

Being able to read assembly language would be helpful - I'm going to have to add that to the list of 'to-dos'.
