So at least you could allow to connect two 74hc595 directly to raspberry pi but your library has only 3 predefined numbers. Why? They will work faster.\r\n\r\n2)I don't know if it is possible in general but... Let we have 74hc595 connected directly to raspberry pi. So we have 2 pins left + each 74hc595 may produce 8 pins: 2 + 8 * 2 = 18 pins. Could we force them to produce even more pins: 18 / 3 * 8 = 48 pins?"},"comment":{"url":"https://api.github.com/repos/mignev/shiftpi/issues/comments/236573788","html_url":"https://github.com/mignev/shiftpi/issues/7#issuecomment-236573788","issue_url":"https://api.github.com/repos/mignev/shiftpi/issues/7","id":236573788,"user":{"login":"chapunazar","id":5246587,"avatar_url":"https://avatars.githubusercontent.com/u/5246587?v=3","gravatar_id":"","url":"https://api.github.com/users/chapunazar","html_url":"https://github.com/chapunazar","followers_url":"https://api.github.com/users/chapunazar/followers","following_url":"https://api.github.com/users/chapunazar/following{/other_user}","gists_url":"https://api.github.com/users/chapunazar/gists{/gist_id}","starred_url":"https://api.github.com/users/chapunazar/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/chapunazar/subscriptions","organizations_url":"https://api.github.com/users/chapunazar/orgs","repos_url":"https://api.github.com/users/chapunazar/repos","events_url":"https://api.github.com/users/chapunazar/events{/privacy}","received_events_url":"https://api.github.com/users/chapunazar/received_events","type":"User","site_admin":false},"created_at":"2016-08-01T13:00:40Z","updated_at":"2016-08-01T13:00:40Z","body":"1) Thats the whole goal and precisely how a shift register, as 74hc595, works. Look it this way, you load the n-pins in series but when latched the values are transfered to the outputs in parallel. "}}
