See Appendix A in Guidelines for Reliable 1-Wire Networks (Application Note 148) for a simple example of a 1-Wire master microprocessor circuit. App Note 148 is definitely the one you should read first, as it specifically sets out to address errors & misconceptions which appeared in earlier App Notes, and other published & unpublished sources! http://www.8052.com/forum/read.phtml?id=19045 Once you have read App Note 148, you should understand the pullup requirements of a 1-Wire network. With this understanding, and the datasheet for your particular 8051 variant, you should be able to determine: A. What pullup is necessary for your particular application; B. Whether the IO structure of any particular port pin on your particular 8051 derivative meets the requirement determined in A. |
