* Fix incorrect delay when setting WS2812 (and similar) leds * Add documentation for WS2812_DELAY_MICROSECONDS * Remove improper cast to uint8_t Co-authored-by: Sergey Vlasov <sigprof@gmail.com> * Remove unneeded cast to uint8_t and correct math Co-authored-by: Sergey Vlasov <sigprof@gmail.com> * microseconds -> µs Co-authored-by: Ryan <fauxpark@gmail.com> * Make documentation better match the spec sheet. Co-authored-by: Ryan <fauxpark@gmail.com> * Rename macro to match spec sheet * Further correction to the delay maths for the SPI case. Co-authored-by: Joel Challis <git@zvecr.com> * Move ws2812_common.h to the drivers directory * Revert "Further correction to the delay maths for the SPI case." This reverts commit e61b56a2cfc7dfec9992a7a3af92afa50e5b8ec0. * Remove ws2812_setleds_pin(); consolidate ws2812.h Co-authored-by: Sergey Vlasov <sigprof@gmail.com> Co-authored-by: Ryan <fauxpark@gmail.com> Co-authored-by: Joel Challis <git@zvecr.com>
