In the example below, "pin" is an object with a number of properties.
Now I want
1- an easy way to create objects that contains a number of these "pin"
2- an multiple way to access these "pin", i.e.
device.pin[some_index]
device.some_logical_name
ad 1:
a dictionary (as "pinlist" in the example) seems a very convenient
way (from a viewpoint of the device creator).
As you can see in the "__init__" section this dictionary can easily be
transported to the pin-objects.
ad 2:
THAT's the problem: how do automate these lines "self.GND = self.pin[0]"
I'm also in for other solutions.
thanks,
Stef
class Power_Supply(device):
pinlist = {
0: ('GND', _DIG_OUT, _par2),
1: ('VCC', _DIG_OUT, _par33)
}
def __init__(self):
# store pin-names and pin-parameters in pins
for k in self.pinlist.keys():
self.pin[k].Name = self.pinlist[k][0]
self.pin[k].Value = self.pinlist[k][2]
# for some pins, we also want to be able to use logical names
# HOW TO USE SOMETHING like
# "self.pinlist[0] = self.pin[0]"
# INSTEAD OF
self.GND = self.pin[0]
self.VCC = self.pin[1]
# create a Power_Supply instance and
# test if pins can be referenced in
Power = Power_Supply()
netlist1 = ( Power.VCC, Power.pin[1], Power.GND, Power.pin[0] )
