+Module Creation Notes
|
|
||||||
+=====================
|
|
||||||
+
|
|
||||||
+For those creating tslib modules, it is important to note a couple things with
|
|
||||||
+regard to handling of the ability for a user to request more than one ts event
|
|
||||||
+at a time. The first thing to note is that the lower layers may send up less
|
|
||||||
+events than the user requested, but only if that was a result of a pen release.
|
|
||||||
+Next, your module should send up just as many events as the user requested in
|
|
||||||
+nr. If your module is one that consumes events, such as variance, then you
|
|
||||||
+loop on the read from the lower layers, and only send the events up when
|
|
||||||
+1) you have the number of events requested by the user, or 2) one of the events
|
|
||||||
+from the lower layers was a pen release.
