Astrobe Forum

Not exactly what I had in mind ;) If nobody can beat Alex's time there will be a second prize of a $US50 Amazon Gift Voucher awarded to the person who submits the fastest module which as well as being faster than the original is also no bigger (code size) than the original. I have also had to amend ...

For all the details see the Oberon Language Forum

A $US50 Amazon Gift Voucher will be awarded to the person who can rewrite the following module so that it produces the same results but executes in the least amount of time: MODULE Quiz; VAR a1*, a2*: ARRAY 1000 OF INTEGER; i: INTEGER; PROCEDURE Init*; BEGIN FOR i := 0 TO LEN(a1) - 1 DO a1[i] := i; ...

The behaviour of DIV and MOD operators with negative operands in Astrobe for Cortex-M3/M4 did not conform to the Oberon language report in v5.1 and earlier versions. This has been fixed in v5.2 of both products. The Oberon language report defines DIV and MOD as follows: The operators DIV and MOD app...

We are planning to introduce a Developer Edition which will include all the features of the Professional Edition with some additional extras. One of these will be the source code of the command-line linker. This will enable you to customise it to suit the memory maps, interrupt vector locations and ...

What specific problem are you trying to solve that you think you could only achieve using inline assembler?

I can't say for sure as I haven't tried it but I don't see why not. You would have to configure the EMC first using the information in Chapter 9: LPC408x/407x External Memory Controller (EMC) of the NXP LPC408x/407x User manual (UM10562). The most transparent way to use the resulting dynamic RAM at ...

Hi Bill, 0X00 is the way you write hexadecimal constants in the C programming language. In Oberon hexadecimal numeric constants must start with a digit and end with an 'H'. e.g. C Oberon 0X00 0H 0X10 10H 0XA0 0A0H or, if you prefer, you can use leading zeroes to make them all the same length: C Ober...

That sounds similar to the one I have on the EmbeddedArtists LPCXpresso Base Board . It uses the SSD1305 Driver / Controller. I haven't yet attempted to use it with Oberon. However, if you hit any problems with your code and there is some compatibility I might be able to use it to help with some tro...

The schematics for the mbed application board with the newhaven display can be downloaded from here: http://developer.mbed.org/media/uploads/chris/mbed-014.1_b.pdf SLC and SDA pins are for an I2C interface. That is completely different from the SPI interface used for the Newhaven display - the pins ...
