Warning :
There are some pins that can work as digital or analogue. In this case, if we have used these
pins before in either digital or analogic and we want to switch its mode, we must call the set
function providing
stop to the value option; otherwise there will be a system error. If a reboot
is done, it is not necessary to do it.
The pins which can operate with both Analog/Digital configurations are:
•
0.5
•
1.5
•
2.5
•
0.6
•
1.6
•
2.6
•
0.7
•
1.7
•
2.7
As for the relay option, we can call the function as the following example:
Respect the PWM, all the digital output pins can work as PWM, so we must also consider the
stop function in case that they are running as digital or analog (in the case of these ones that
can work as analog or digital).
Or:
./set-digital-output Q0.5 1
./set-digital-output Q0.5 stop
./set-analog-output Q0.5 4095
./set-analog-output A.05 50
./set-digital-output Q0.5 1
./set-digital-output Q0.5 stop
./set-analog-output A0.5 2048
./set-analog-output A.05 50
./set-analog-output A0.5 2048
./set-digital-output A0.5 stop
./set-analog-output Q0.5 4095
./set-analog-output A.05 50
./set-relay R0.5 1
