Re: Is a suppurt of freescale cortex m4 thinkable ???

A wild guess - maybe 3x - 4x more effort.
Chris, Is this an answer to Q1 or Q2.

Re: Ethernet code

What Hardware do you (intend to) use?; Astrobe is especially targeted to NXP processors.
Arduino is mostly AVR & 8 bit based except for the recently introduced Arduino Due.
I would love to see Astrobe / Oberon M07 run on this though..

Re: Ethernet code

Yep, I've done so. Be warned. Using the ENC28J60-H alikes means you need to REWRITE the entire TCP-IP stack. No Easy task because of sveral limitations in Astrobe Implementation. You can't simply port C-code... A better alternative is to use the WizNet 5100 or WizNet5200 chip based solution which ha...

Generating a MD5-Hash

As the coming generation of ARM MCU's contains support for MD5, I thought it a good exercise to port some code over to the M3-Generation. In short explained: MD5 generates a 32 Bytes long code that you can use to identify a block of text/code/data with. Even if only 1 bit of that block of text/code/...

MOD-TC interface example

I also created code to interface this module with Olimex LPC1766-STK, (see topic in LPC2000) MODULE MAX6675; (* The primary use of the library is to easily interface with a MAX6675 chip via it's PSEUDO-SPI interface. Use the following code to initialize the library. units is one of the following: 0 ...

MOD-TC interface example (TC=Thermo Couple)

With this Olimex module you can measure the temperature inside of your oven! The module measures temperatures of up to 1000 deg. Celsius. I didn't try that, but made it show the Room-temperature. The MOD-TC interface uses MAX6675 IC and uses a pseudo SPI-interface. With pseudo I mean that it is usin...

Olimex MOD-RTC interface exampe

While most NXP processors do have a RTC on-board, I think you can never have enough examples of interfacing. This examples shows interfacing with Olimex UEXT plugin module, in this case combined with LPC2378-STK board. The clock using I2C interface. After some study of MOD-RTC schematic I have creat...

Re: Concatenating string constants

Does this influence the current 60 character limitation?

I opt for more consistent rules: e.g.:

CONST
Pi =3.14159268;
twoPi = 2*Pi;

This should not give compiler errors..

IDE Error/Message handling

Whenever the inevitable happens while developing code (coding-errors) the bottom part of the IDE shows the compiler warnings and errors. Problem I experience with that is the cursor remains on the BOTTOM of that list. I'd like the cursor to be positioned on the TOP of that list, preferably on the li...

LPC2378 PWM generating a clocksignal

With a future implementation of an IR-module in mind I toyed with some code from the NXP boys. After translating it to Oberon I made a simple test and monitored the results from my Logic Scope. For IR transmission you need a 36 to 40 khz clocksignal with a Duty cycle of about 25%. This means the Clo...
