Re: Simplecortex: LPC1769 Arduino Format

Thanks for the explanation of the LPC1769 memory organization. I was looking for that in the manual. I have to admit I was overwhelmed by the size of the user manual: a sheer 840 pages*. So I have here a processor that has the abilities of a little personal computer. And all this power is harnessed ...

Simplecortex: LPC1769 Arduino Format

I'm tring to run this board http://www.brc-electronics.nl with Astrobe. It looks like it has an interface similar to the lpcXpresso. Actually it is designed by an intern at NXP so some resemblance is probably not a coincidence. I want to use this board at my school. We have some arduino's for scienc...

Re: New language extension: Allow underscores in identifiers

Thanks for your reply
I will try out your recomendations on aliasing constants.

Re: New language extension: Allow underscores in identifiers

Some considerations about naming register constants. I'm also wrestling with the uppercase names of registers in datasheets. PWMMCR cannot be considered "self explaining" - code. I prefer the camelBack style over the underscore style. pwmMCR vs PWM_MCR However the abriviations are still cryptic and ...

Re: Ethernet code

To wrap it up: today i programmed an arduino to contol a servo, some switches and leds. It worked, however from a didactal perspective, very difficult te explain to students. The major problem are the unqualified imports. All kinds of procedures are used without reference. Besides, the arduino IDE d...

Re: Ethernet code

I use an embedded artist educational board lpc 2138
I have a personal licence for astrobe edition 4.0.2

The example code above is indeed written for avr, but it is well documented.
The arm (in c) examples from Keil if find confusing.

Did you already have written a module for the wiznet5100?

Re: Ethernet code

The wiznet5100 is a good start. I found very readable example for programming the Wiznet5100 at this site. The code is written for an avr micro http://www.ermicro.com/blog/?p=1773 To give an impression how readable the code, see the following declaration part of the program wiznetping.c. There are o...

Re: Ethernet code

Thanks for your considerations about the ENC28J60. I thought that the ENC28j60 was an alternative for the Wiznet chips. Now i understand that the programming stack compilicates maters even more. I use the arduino to experiment with microcontrollers with students. Take a look at the project at Lyceum...

Ethernet code

I would like to use Astrobe to program ethernet applications. Does anyone have experience with interfacing Astrobe with ethernet chips like the ENC28J60?

Greets,
