* After more analysis and coding * More work is done, writing/reading WIP * `write` prototype done, small fixes. Read next * pre-rebase * Rebased and updated * Pre-final state of driver * More work (near-final state) done * WIP * WIP * working * cleanup * changelog * address review comments * remove Option from conjure and improve lp-i2c example description --------- Co-authored-by: Kirill Mikhailov <konnor1980@yandex.ru>
