4 The SX-Key/Blitz Interface
Program
Make the necessary corrections to the source code, and assemble the code again,
until no more errors are reported.
The assembler may also generate warning messages that are shown in the same
area, together with any errors. With warnings, the code will be assembled, but it
is a good idea to make the necessary corrections to the source code in order to
avoid warnings.
NOTE: Before assembly, the current file will be saved automatically. If you have
entered code into a new blank editor window, use the Save function to save the
window contents under a specific name before starting the assembler.
Assembles the source code and programs the SX microcontroller (when the
assembly was successful). Ctrl-P also starts programming.
Run
Assembles the source code, programs the SX and generates a clock signal. Ctrl-R
also runs a program.
Debug
Assembles the source code, programs the SX, generates a clock signal and
initiates the debug mode. (Not used on the SX-Blitz). Ctrl-D also starts the
debugging mode.
Debug (reenter)
Assembles the source code, assumes that the SX device is already programmed
with the recent code to be debugged (i.e. does not program the SX again),
generates a clock signal and enters the debug mode. (Not used on the SX-Blitz).
Ctrl-Alt-D also re-enters the debugger.
This option is handy when you have previously terminated a debug session that
you want to continue later without having made changes to the source code in
the meantime.
As long as you add, remove or change WATCH or BREAK directives in the
source code, you may still use this function to reenter the debugging session
without downloading the program to the SX.
Any other changes to the source code require a new download, i.e. you must use the
Debug option instead, to start the debugger.
