7.12 Memory Select Switches
There are two, two-pole Memory Select switches available on Venture, which
allows the user tremendous flexibility in switching between configurations. These
switches may be either momentary or static and are configurable to be either
pull-up or pull-down through the settings tab in IDS.
Up to four memories can be configured on Venture. Memory A must always be
valid. All memory select options are selectable via the settings tab in IDS.
7.12.1 Momentary Switch on MS
This mode uses a single momentary switch on MS (Pin 4) to change memories.
Using this mode will cause the part to start in Memory A and whenever the button
is pressed the next valid memory will be loaded. When the user is in the last valid
memory, a button press will cause memory A to be loaded.
This mode is set by programming the “MSSMode” parameter to “Momentary” and
“Donly” to “disabled”.
Examples
If 4 valid memories ABCDABCDA…
If 3 valid memories ABCABCA…
If 2 valid memories ABABA…
If 1 valid memories AAA…
7.12.2 Momentary Switch on MS, Static Switch on MS2 (jump to last memory)
This mode uses a static switch on MS2 (Pin 5) and a momentary switch on MS
(Pin 4) to change memories. If the static switch is OPEN, the part will start in
memory A and it will behave like momentary with the exception memory D will not
be used. If the static switch on MS2 is set to HIGH, the part will automatically jump
to memory D (this will happen on startup or during normal operation). In this setup,
the momentary switch's state is ignored. This prevents memory select beeps from
occurring. When MS2 is set to OPEN, the part will load in the last select memory.
This mode is set by programming the “MSSMode” parameter to “Momentary” and
“Donly” to “enabled”.
Examples
If MS2 = OPEN and there are 4 valid memories: ABCABCA…
If MS2 = OPEN and there are 3 valid memories: ABABA…
If MS2 = HIGH: D…
