# MKS 979B Atmosphere to Vacuum Transducer driver
## Intro
A Platform agnostic, `no_std`, serial communication driver for the MKS 979B Atmosphere to Vacuum Transducer, based on the embedded-hal traits.
- Implements the RS485/RS232 communication protocol specification for the MKS 979B
- Works in standalone use and via MKS PDR 900 Series controllers.
## Status
The driver is technically complete, but some further testing is required for some commands as to verify nothing behaves in a weird way.
All commands for the 979B Transducer are implemented. PDR 900 commands are out of scope for this crate.
## Usage
An simple blinky example is provided for the ItsyBitsy_m4. The API is quite straight forward.
### Why not use type states for the query functionality?
Type states were considered at some point but it sacrifices some comfiness in certain use-cases. This just means the user must make sure the sequence `schedule_message`-`send_message`-`poll` is correctly followed.
