1 Wire Component Request - of sorts!
Posted: Mon Feb 19, 2018 10:43 pm
Hi,
I've been struggling trying to develop a 1wire search routine for multiple devices for a while now and I have to give in and have to ask for some help, not only with a search routine but also the CRC calculation.
Would it be possible to have a component based on the DS2480B Line Driver which not only enables 1wire devices to be used upto 200m but incorporates a large portion of the Search Algorithm on die. The DS2482 also as this functionality and is a bridge based on I2C whereas the 2480B is a serial bridge device.
The reasons I said "as sorts" is that having this is a 'building block' component it will open the door to all the other 1wire devices over long distance which HAS too be useful to Flowcode Users.
What would be fantastic is to have a macro that presents us with ROM IDs and the calculated CRC so that we can store these values and therefore read and write to specific devices at will.
Thanks
Matt
