  We present the outlines of a new microcontroller based data acquisition
system which is aimed for reliable operation in a typical cosmic ray particle
registration experiment. The system supports connection of up to 16 input
signals and ensures the following operation functionality: (1)stable monitoring
of the intensity of a digital pulse signal, or digitization of a continuous
potential level with a low time resolution (typically, in the limits of
1-100s); (2)registration of a continuous high-resolution (up to 5-10us) time
series of the intensity of input signal; (3)synchronization of registered time
series with both external (physical) or local (program-based) trigger signal;
(4)possibility of an on-the-fly change of the whole configuration of
informational system (both the combination and type of input signals, time
resolution and sum duration of the time series measurements, trigger logic,
etc) immediately in operation time through convenient communication with a
plain text message in dialog mode. In particular, the considered system is
applied now for a long-term, high precision measurement of the counting rate of
neutron signals at the NM64 type neutron supermonitor of the Tien~Shan mountain
cosmic ray station, with a real-time representation of the whole collected
dataset in a WWW database.
