VisUAL - A highly visual ARM emulator

Migrating Code to Keil

VisUAL uses the same syntax as the Keil µVision software developed by ARM. However, some care must be taken when moving code written in VisUAL to Keil. The following changes will be required as a minimum:

Move the code into a new AREA - See the official Keil µVision User Guide for an example here
Make sure that the first line of code in this AREA is an instruction and not a directive, otherwise you will get a compilation error.
Map any memory regions for which you require read/write access - A guide by Dr. T.J.W. Clarke is available here. You will need to use you Imperial College username and password to obtain access.
All instructions must be indented by at least one tab, else opcodes will be considered labels and you will not be able to compile code.
And END directive must be placed at the end of the file otherwise you will get a compilation error.

Migrating Code to VisUAL

Provided that you are only using instructions from the list of supported instructions, simply remove the AREA preamble and the code will work in VisUAL. If your code uses interrupts or multiple processor mods, this is not currently supported.

You may have to edit memory usage depending on the memory map configuration.
