view most significant bit

[ibwev]

How do I view the most significant byte of a 2 byte variable? I have attached a section of code that I am using. The variable "RPM" under View:Watch of MPLAB is only1 byte long.

In MPLAB you can watch virtually any variable...just put them in order.. lowByte and then HighByte

would that be under "view" then "watch" ? i'm curiouse also, i've been just movfw then movwf of say portc????

Thanks for the response.

When I declared the 2 byte variable, I set it up this way:

variable res 2

To be able to view the variable, should I set it up this way:

variableLOW res 1
variableHIGH res 1

View variables under View:Watch of MPLAB then "Add SFR" (Special Function Register) and/or "add GPR" (General Purpose Register). Apparently, only 1 byte of a variable can be viewed.

When vladimir from oshonsoft declares int's and long's he uses R0L , R0H, R1L, R1H.. This way when you watch the variable you can select them from the drop down box in the watch window.

With MPLAB (using assembler) you can view and modify from a single bit to 4byte floating point numbers. Add the variable to Watch, right click it, popup allow you to select format.
