Versatile
Small RTOS
Benjamin
Kacenas
You
can implement Benjamin’s processor-independent small
RTOS while providing a small footprint and multiple
levels of determinism. He has used the RTOS in consumer
electronics applications of various sizes. Now it’s
your turn to try it in an application of your own.

Yourself: Assemble an ARM7 Tool Kit
Fred
Eady
If
you’re an ARM adventurer like Fred, you’ll want
to assemble a working set of ARM development tools
to program and debug ARM7-based devices for your
future applications. This month, Fred shows you
how to assemble a tool kit around a Segger J-Link
ARM emulator. p. 70
Keywords:
ARM7,
J-Link emulator, LPC2148, J-Link Commander, J-Mem,
debug, RDI, IAR Workbench

Universal
In-Circuit Programmer
Stuart
Ball
Devices
such as Microchip PICs and Atmel AVRs have serial
interfaces for programming. Normally, you have to
use a different programmer for each one, but not
anymore. Stuart’s universal in-circuit programmer
can handle most clocked protocols. p. 76
