MQX Software for ColdFire
Microcontrollers
Freescale provides MQX embedded software
optimized for ColdFire architecture. MQX
offers a full-featured kernel RTOS with small
configurable memory footprint and optimized
real-time performance. MQX is complimentary
for the MCF51EM family, and is available
with full source code. MQX will shorten
your development cycle while allowing you
to focus on application development by
incorporating a rich set of demos, including:
Single-Phase Electricity Metering
Accurate electrical parameters measuring
by using the combined ADC, PDB and
voltage reference module while utilizing
the MQX critical mode interrupt handling
method for timing critical situations.
