Pure Crystal implementation of Bit Fields. Handles encoding/decoding of bytes.
- Add the dependency to your
shard.yml:
dependencies:
bitfields:
github: elorest/bitfields- Run
shards install
require "bitfields"
class CrossBit < BitFields
bf rpms : UInt32, 32
bf temp : UInt8, 4
bf psi : UInt16, 9
bf power : UInt8, 1
bf lights : UInt8, 2
end
crossbit = CrossBit.new(Bytes[109, 121, 110, 97, 109, 245])
crossbit.temp #=> 13_u8
crossbit.psi #=> 342_u16
crossbit.power #=> 1_u8
crossbit.lights #=> 3_u8
crossbit.to_slice #=> Bytes[109, 121, 110, 97, 109, 245]
crossbit.to_s #=> |lights|power|psi|temp|rpms|
#=> |11|1|101010110|1101|01100001011011100111100101101101|
crossbit.power = 0 #=> 0_u8
