| + | ====System Variables==== | ||
| + | The development environment provides a series of ready-made variables that can be used by putting the word " | ||
| + | This paragraph is designed to illustrate the 16 system variables called sys001-sys016, | ||
| + | == sys001 == | ||
| + | This is a read only variable that indicates the status of the FUNC (bit 0) and BOOT (bit 1) buttons. The following settings are possible:\\ | ||
| + | 0 = no button pressed.\\ | ||
| + | 1 = FUNC button pressed.\\ | ||
| + | 2 = BOOT button pressed.\\ | ||
| + | 3 = FUNC and BOOT buttons pressed. | ||
| + | |||
| + | == sys002 == | ||
| + | This variabile allows to read a dump of the SW1 dip-switches. The dump is acquired only after the controller is powered. The Bit 0 corresponds to dip 1 and so on. | ||
| + | |||
| + | NOTE: Some dips are not connected to the microprocessor and is therefore always read at logic level 0. | ||
| + | |||
| + | == sys003 == | ||
| + | This variable allows the command of led's L1-L2-L3-L4. The bit 0 corresponds to L1, the bit1 to L2 and so on. | ||
| + | |||
| + | ==sys004== | ||
| + | This variable allows toxet the anti-glitch filter on the phase signals in the two-way counters. The setting is expressed in KHz and refers to the signal frequency of one phase. The setting range is 30-220. | ||
| + | The default setting is 220KHz. The variable can also be reread. The filter can be modified at any time. | ||
| + | |||
| + | ==sys005-16== | ||
| + | Not used. | ||
