Release v4.2 of Astrobe for Cortex-M3 has a new Oberon language extension - the built-in procedure BITS: PROCEDURE BITS(i: INTEGER): SET; BITS is a feature of the language Component Pascal (i.e. Oberon-2+) which we use to develop the Astrobe Oberon compiler. BITS takes an INTEGER parameter and retur...

Does this influence the current 60 character limitation? No - that is a separate issue. The concatenated CONST string would be limited to 60 characters unless the limit was also increased. I opt for more consistent rules: e.g.: CONST Pi =3.14159268; twoPi = 2*Pi; This should not give compiler error...

We have now successfully tested the LPC-P1343 and LPC-1766STK prototype boards from Olimex so we have added them to the list of supported development boards:

The following example works on the LPC1751 and LPC1756 boards from Coridium. MODULE Blinker; (* Example Cortex-M3 Oberon Program for NXP LPC17xx Led connected to P2.10 blinking approx. once per second *) IMPORT Main, MCU, SYSTEM, Timer; PROCEDURE Run(); CONST (* led connected to pin P2.10 *) ledBit ...

We are considering implementing an extension to Oberon in Astrobe to allow the use of + as a concatenation operator for string constants. This would be useful if you wanted to include double-quotes or non-printing characters in strings. e.g. CONST QuotedString = 022X + "String" + 022X; or if you pre...

We are still on track (despite the temporary diversion to implement the changes caused by the 2011 revision of Oberon) to our August 2011 announcement:

"Q2 2012 or possibly Q1 2012 if everything goes as planned"

(By the way, when it comes to export of variables I would also have liked to be able to export character arrays which makes sense since strings can be exported.) That does not follow. strings are constants character arrays are variables . In the case of executables created using Astrobe the differe...

... my standpoint is that the inability to modify an exported field though an exported pointer (as in my example) represents a minor compiler bug That is not correct. Unless I have misunderstood what you are saying I believe you have 'got the wrong end of the stick'. The system is designed to try t...
