I have been experimenting with K8055 board for some time using provided demo software and realised it would be good to be able to perform more complex actions. A friend of mine wrote a new application with these additional features:
[ul][b]logging[/b] of all channels to a file and viewing in different programs (sampling time from 50 ms up)[/ul]
[ul][b]saving[/b] the state of all controls to a file for later reuse[/ul]
[ul]continuous adjustment of counters debounce time[/ul]
[ul][b]automatic control[/b] of channels:
[list]state of digital outputs based on the state of digital inputs[/ul]
[ul]state of digital outputs based on analog inputs, including [b]hysteresis[/b] (regulation, schmitt trigger)[/ul]
[ul] level of analog and PWM outputs based on analog inputs (positive or negative gain, with offset)[b] (buffers, amplifiers, negative feedback control loop)[/b][/ul]
[ul][b]scheduled[/b] operation of all outputs and resetting of counters (using time of day or separate time)[/ul][/list:u]
I have already used the software in a couple of ways:
[ul]To [b]monitor and control charging of lead-acid battery[/b]. I could set the voltage levels at which the charging current is to be lowered and at which the charging should stop. Using recorded values of voltage and current I obtained detailed [b]profiles of charging.[/b][/ul]
[ul]To [b]switch periodicaly[/b] the air conditioning fan and record the changing voltage of the battery serving as a power supply.[/ul]
[ul]To record the [b]frequency of the AC power line[/b]. It reflects overall loading of electric power distribution system, which is interesting to observe.[/ul]
