v1.2.0 - 2022-01-23
- Updates
- Add the
:lsb_first
option to support SPI transfers that send the least significant bit first rather than the most significant one. If the bit reversal isn't supported by the hardware, a software version is used. - Add
config/1
to return the configuration for an SPI bus reference. This is useful for checking what is actually being used. - Update
transfer/2
to supportiodata
. This makes the interface more convenient since now you can prepend SPI message headers in your code without having to concatenate binaries. - Support full pathes being passed to SPI devices in
open/2
. Previously this resulted in errors, but it was easy to forget.
