ARM Microcontrollers with an ABB?

I was looking at alternative controllers to try out, and saw this item which looks like it might be workable. Runs at same power/pins as the Atom Pro, only at 60 MHz instead. (And its slightly cheaper than a Basic Atom/Atom Pro)

  • ARM7 CPU running at 60 Mhz (LPC2103)
  • Programmed via Serial interface
  • BASIC compiler runs >10 million lines of codes/sec
  • 32K Flash memory with 12K available for user code
  • 8K SRAM memory with space for 1,000 user variables
  • Onboard regulated power supply runs off 5-12V DC input
  • 6 10bit AD converters, 100 KHz sample rate
  • 6 10bit Hardware PWM channels
  • Compatable with other DIP24 module pin outs

The main difference seems to be that it is active low on Pins 1,2, 22/26 (SOUT, SIN, RES) compared to the 24/28 pin atom modules.

Would this even be workable in the current ABB boards or is the active low on the serial pins a show stopper?

The BASICAtom24 is pin compatable with Parallax’s BASIC stamp. The Coridium ARMexpress and ARMexpress LITE are also pin compatable with the BASIC stamp.

In the BASICAtom documentation SIN,SOUT and ATN are not noted to be inverted, but as they connect directly to an RS-232 port, those signals are inverted.

So the Coridium products should be a drop in replacement. One thing we have seen is that if there is no connection to SIN/ATN there needs to be a 1K pullown to GND added to the circuit on ATN.
