Is the original source code NW's ARM compiler available, as it is for Project Oberon? Not that I'm aware of. It was rendered obsolete many years ago by the version that is included in Project Oberon. The major difference is the code generator. The RISC5 version is only just over 1000 lines of code ...

If you are configuring the pin for I2C the Astrobe GPIO module automatically enables the pull-up resistor for the pin. If you have the source code for the Astrobe GPIO module you can see how it is done there. Otherwise, for other GPIO pins, the relevant bit, PUE ( P ull- U p E nable), is identified ...

Thank you for pointing that out. I'll update the docs accordingly. At the risk of being picky, the writer of the Oberon Compiler for the ARM Processor was Niklaus Wirth. I'm merely modifying the code generator to target other Arm processors. There is no way in the world I could have done that withou...

And this strictly works with BOOLEAN CONSTs only, correct? Correct. It has always been possible to parameterise code in the way you describe - the Conditional Compilation feature just makes it less inefficient than it otherwise would be. However that was not the intended use of the feature and I wo...

Does the quoted statement mean that the nested 'IF F1 ...' gets included? Yes. If you compiled your code with v10 you would get the same code generated as if you compiled the following with v9.3: CONST T0 = TRUE; F1 = FALSE; PROCEDURE P4(); BEGIN IF F1 THEN Included() (* ?? *) END END P4;

There are four possible combinations for the values of Trace.enabled (TRUE / FALSE) and OtherTrace.enabled (TRUE / FALSE). This is shown by the following hypothetical example. None of the calls to the procedure Eliminated are generated. MODULE Elsif; CONST F1 = FALSE; F2 = FALSE; T1 = TRUE; T2 = TRU...

In the process of testing a module it is often very useful to add diagnostic traces to monitor progress. As these diagnostics are generally only required for development they can be turned off for the release version of the application using various CONST declarations. A new optimisation feature, Co...
