bunnie 95b857feea refactor i2c interface to eliminate static mut unsafes ... also remove async write callbacks: in practice, these aren't used Downside of this refactor is that threads for handling the callbacks are not spawned on demand, they are spawned at boot, leading to about an extra 68k of RAM used (most of it being consumed in the codec block, actually). Some of this is also probably extra object code because we're using more of the stdlib primitives, which carry some weight.		2022-02-19 00:31:25 +08:00
