Can someone help me with the configuration for iButton in Flowcode 5? I do not know how to set my custom components ... I need, for a simple door lock, to identify the serial number of a Dallas ds1990a to pass the lock. If there is someone who have an ready made example in Flowcode with Ibutton, please post it here. Thank you in advance!

Hello,
I think the iButton devices should work with the OneWire component though I have not tried this in practice.

Benj, thank for your reply!
I think the same as you, only that I do not know how to send and receive commands on that one wire device, I read the datasheet of the DS many times but no luck... that's why I posted here, maybe it is somebody who have work with it.

Hi
Thanks for the email. I have ordered that from china but wait for whole 1 month and asked the supplier. They immediately refunded the money and I forgot why I have ordered those. Yesterday I got those in hand and see I have ordered for you. Thanks for knocking I will test and let you know soon. Not possible in week end as those in Uni and I have returned.

The HW is ready
. All I have to do is to "fill" the "read_key" variable...

Problem solved!
Thank to a colleague of our forum -
aura809 -, I understand how Ibutton work!
It is quiet simple:
First, you have to ensure that is an Ibutton on the bus with "00_scanbus" and if there is an Ibutton, read the serial number byte by byte with the "00_get_IDByte" changing the octet from 0 to 7 for all eight bytes of the serial numbers... And that`s all folks
Thank you Alen again for your help!

The FC its "on the way". I had to change the HW, because the RAM of the 683 was insufficient for that project. I use now 16F88 and 16x2 LCD.
I don`t have much time to finished that... Mean while, I will post an example only with the part of the reading of the serial number. You will see, its very simple
Later edit:
This is an simple example to see how to read the iBUTTON.
