33 Association of a Signal, and evaluation trigger, with a Count.

58 A Synapse represents the association of a Signal with a Count. Signal
59 data affects respective Count data, and the Synapse represents this
63 triggers the respective Count's count function evaluation to update the
64 count data. The Generic Counter interface provides the following
68 Signal does not trigger the count function. In Pulse-Direction count
80 A counter is defined as a set of input signals associated with count
82 input signals as defined by the respective count functions. Within the
85 instances represent the count function update conditions for the
88 A Synapse associates one Signal with one Count.
90 COUNT section in Theory
92 A Count represents the accumulation of the effects of connected
93 Synapses; i.e. the count data for a set of Signals. The Generic
94 Counter interface represents the count data as a natural number.
96 A Count has a count function mode which represents the update behavior
97 for the count data. The Generic Counter interface provides the following
98 available count function modes:
101 Accumulated count is incremented.
104 Accumulated count is decremented.
107 Rising edges on signal A updates the respective count. The input level
116 updates the respective count; if the direction is backward, falling
117 edges on quadrature pair signal A updates the respective count.
122 updates the respective count; if the direction is backward, falling
123 edges on quadrature pair signal B updates the respective count.
128 respective count. Quadrature encoding determines the direction.
132 respective count. Quadrature encoding determines the direction.
136 respective count. Quadrature encoding determines the direction.
138 A Count has a set of one or more associated Synapses.
143 The most basic counter device may be expressed as a single Count
145 a counter device which simply accumulates a count of rising edges on a
148 Count Synapse Signal
151 | Data: Count | Rising Edge ________
157 voltage, while the Count is a persistent count value which is repeatedly
158 incremented. The Signal is associated with the respective Count via a
162 behavior is aptly represented by respective Count, Signal, and Synapse
164 accumulating count datum.
167 many Signals may be associated with even a single Count. For example, a
171 Count Synapse Signal
184 associated with a single Count: a rising or falling edge on either A or
188 encoder counter device; the Count, Signals, and Synapses simply
191 Signals associated with the same Count can have differing Synapse action
197 Count Synapse Signal
212 both Signals are associated with the same Count via two respective
214 triggers the respective count function while the other is left with a
218 Keep in mind that the Signal, Synapse, and Count are abstract
288 exposure and configuration of a specific Count or Signal respectively.
300 * Count extensions are attributes that expose information/control
301 specific to a Count. These type of attributes will exist under a
302 Count's directory in sysfs.
304 For example, if you want to pause/unpause a Count from updating, you
305 can have a Count extension called "enable" that toggles such:
309 non-specific to a particular Count or Signal. This is where you would
343 Similarly, each Count has a directory created to house its relevant
344 sysfs attributes, where Y is the unique ID of the respective Count:
357 respective Count attributes; similarly, the same is true for the
