Another idea (can be added to the above ?)<br>
|
|
[gpio.configport(gpio.[FUNCTION], gpio.MASK, [MASK])]<br>
|
|
Ex:<br>
|
|
gpio.configpin(gpio.DIR, gpio.DIR_INPUT) (.DIR_OUTPUT)<br>
|
|
gpio.configpin(gpio.PULL, gpio.PULL_UP) (.PULL_DOWN, PULL_NO)<br style="font-family: Verdana;">

|
|

|
|
pio.port_input( Port1, Port2, ... ): set the specified port(s) as
|
|
input(s).

|
|
output(s).

</p>
|
|
<p class="MsoNormal" style="font-family: Verdana;">
|
|
|
|
</p>
|
|
<p class="MsoNormal" style="font-family: Verdana;">
|
|
[gpio.configpin(gpio.PULL, gpio.PULL_UP, [Pin1], [Pin2], ...)]
|
|
pio.pullup( Pin1, Pin2, ... ): enable internal pullups on the specified
|
|
pins.Note that some CPUs might not provide this feature.
|
|

|

<p class="MsoNormal" style="font-family: Verdana;">

</p>
|
|
<p class="MsoNormal" style="font-family: Verdana;">
|
|
[gpio.configpin(gpio.PULL, gpio.PULL_DOWN, [Pin1], [Pin2], ...)]
|
|
pio.pulldown( Pin1, Pin2, ... ): enable internal pulldowns on the
|
|
specified pins. Note that some CPUs might not provide this feature.
|

specifiedpins. Note that some CPUs might not provide this feature.

|
|
<br>What is the real advantage/reason of having a pin "list" on some of
|
|
these functions ? If we cannot build a table with them, there's really
|
|
no great use of this, as we cannot create the list in run time and some
|
|
other proposed functions solve the problem of avoiding more than one
|
|
call for several pins.<br>A: It IS usefull and sometimes necessary so it will stay.....<br>
