Can be run on the fly, does not require to setup the SPI port again. You change the mode, do a 16 bit send, change the mode again, do an 8 bit send. It helps a lot with displays that use 16bit for colors, as it goes from 2 SPI transactions to only 1."},"comment":{"url":"https://api.github.com/repos/rogerclarkmelbourne/Arduino_STM32/issues/comments/104668070","html_url":"https://github.com/rogerclarkmelbourne/Arduino_STM32/pull/58#issuecomment-104668070","issue_url":"https://api.github.com/repos/rogerclarkmelbourne/Arduino_STM32/issues/58","id":104668070,"user":{"login":"RickKimball","id":277696,"avatar_url":"https://avatars.githubusercontent.com/u/277696?v=3","gravatar_id":"","url":"https://api.github.com/users/RickKimball","html_url":"https://github.com/RickKimball","followers_url":"https://api.github.com/users/RickKimball/followers","following_url":"https://api.github.com/users/RickKimball/following{/other_user}","gists_url":"https://api.github.com/users/RickKimball/gists{/gist_id}","starred_url":"https://api.github.com/users/RickKimball/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/RickKimball/subscriptions","organizations_url":"https://api.github.com/users/RickKimball/orgs","repos_url":"https://api.github.com/users/RickKimball/repos","events_url":"https://api.github.com/users/RickKimball/events{/privacy}","received_events_url":"https://api.github.com/users/RickKimball/received_events","type":"User","site_admin":false},"created_at":"2015-05-22T14:03:54Z","updated_at":"2015-05-22T14:03:54Z","body":"I guess I'd like the see the SPI API consistent with all other Arduino SPI implementations. That way it is easier to move scripts across machines without the user having to change things.\r\n\r\nIf nothing else, you should spew a warning when you compile that the user is using a platform specific API method.\r\n"}}
