#149001 - 1-wire interface |
Hello.
I am working with AT89C5131 and we use 1-wire device(ibutton) Firstly, we were going to use DS2480 1-wire driver but we thought we can implement 1-wire interface without this chip. But I come to think 1-wire interface need releasing of the port in reset, bit transfer but I wonder this is possible in atmel micom. I think this is possible in CPU or micom where GPIO can be configured as input or output freely, but I wonder this is possible in this atmel micom. I didn't do much job on micom, so I don't know much about it. but as far as I think, we should use DS2480. Please tell me this is possible in atmel micom or we should use DS2480. Please answer. Thanks. |
