Astrobe Forum

Two in-line functions in Astrobe for Cortex-M are used to efficiently extract or update a bitfield, i.e. just a portion of 32-bit word. Each efficiently uses a single Thumb-2 instruction: BFI: Bitfield Insert UBFX: Unsigned Bitfield Extract PROCEDURE BFI*(VAR x: INTEGER; msb, lsb, y: INTEGER); PROCE...

ResData: I cannot find any reference to a constant value named ByteOffset in ResData.mod. I can see that a constant value BytesOffset is used and this is correctly declared as a constant = 20. SunRise / SunSet: Sorry about the confusion - the example was developed on an earlier version of Astrobe. I...

A subtle but significant enhancement to the SYSTEM.VAL function was introduced in v5.1 Astrobe. The use of the System.VAL type-transfer function is no longer restricted to using basic types. Previously the definition of SYSTEM.VAL was: PROCEDURE VAL*(typeName: <any basic type>; x: <any basic type or...

I just had a quick look. As you have configured the pins to use I2C2 then you must change any references to I2C0 to be I2C2 e.g.
If you still can't get it to work, let me know and I'll try your code on a board here.

Do I need to write the ConfigurePinsProc myself, if so, where does it belong? On the 'myapp'.mod or the Main.mod(for the 1768) Yes. Put it in the same module where you call I2C.Init. Use the LPC1769\Olimex Accelerometer example as an example of what you need to do. It is likely that you will be abl...

The first error message is usually the more important one. In this case it was: 18 14 Error: undefined Line 18, column 14 is the end of the word init . Oberon is case-sensitive, the correct name of the procedure is Init with a capital 'I'. However, you do not need to initialise the serial port as th...

Embedded Artists' mbed-enabled Cortex-M4 LPC4088 QuickStart board is now supported for use with Astrobe for Cortex-M4. Follow these instructions to get started by building a simple example application written in the Oberon programming language to run on your QuickStart board: 1. Connect your LPC4088...

See the announcement Astrobe for Cortex-M4 v5.2 has now been released

Thanks Bill - your comments are very much appreciated although I must acknowledge that a significant amount of the credit is due to Prof Wirth.

If you do have any 'newbie' questions related to the Oberon language itself feel free to ask them here,

Cheers,
Chris

I'm sorry about the delay in replying - I only just discovered your post was waiting for approval. I have now updated your profile so that any future posts from you will not have to go through the approval process. 1. The only Cortex-M3 development boards we currently support are from NXP. 2. I woul...
