Abstraction for LTC681X family. Supports all devices of LTC681X family: [LTC6813](https://www.analog.com/en/products/ltc6813-1.html), [LTC6812](https://www.analog.com/en/products/ltc6812-1.html), [LTC6811](https://www.analog.com/en/products/ltc6811-1.html) and [LTC6810](https://www.analog.com/en/products/ltc6810-1.html).
Currently, the following features are implemented:
* [Cell and GPIO conversion](https://docs.rs/ltc681x/latest/ltc681x/monitor/index.html#conversion)
* [Reading cell and GPIO voltage registers](https://docs.rs/ltc681x/latest/ltc681x/monitor/index.html#reading-registers)
* [Multiple devices in daisy chain](https://docs.rs/ltc681x/latest/ltc681x/monitor/index.html#multiple-devices-in-daisy-chain)
* [ADC status polling (SDO line method)](https://docs.rs/ltc681x/latest/ltc681x/monitor/index.html#polling)
* [Mapping voltages to GPIO and cell groups](https://docs.rs/ltc681x/latest/ltc681x/monitor/index.html#mapping-voltages)
* [Abstracted device configuration](https://docs.rs/ltc681x/latest/ltc681x/config/index.html)
* [Overlapping ADC measurement](https://docs.rs/ltc681x/latest/ltc681x/monitor/index.html#overlap-measurement-adol-command)
* [Internal device parameters measurement](https://docs.rs/ltc681x/latest/ltc681x/monitor/index.html#internal-device-parameters-adstat-command)
## Example
For all details see [monitor](https://docs.rs/ltc681x/latest/ltc681x/monitor/index.html) module.
````Rust
use ltc681x::example::{ExampleCSPin, ExampleSPIBus};
use ltc681x::ltc6813::{CellSelection, Channel, GPIOSelection, LTC6813};
use ltc681x::monitor::{ADCMode, LTC681X, LTC681XClient, PollClient};
let spi_bus = ExampleSPIBus::default();
let cs_pin = ExampleCSPin{};
// LTC6813 device
let mut client: LTC681X<_, _, _, LTC6813, 1> = LTC681X::ltc6813(spi_bus, cs_pin)
.enable_sdo_polling();
// Starts conversion for cell group 1
client.start_conv_cells(ADCMode::Normal, CellSelection::Group1, true);
// Poll ADC status
while !client.adc_ready().unwrap() {
// Conversion is not done yet
}
// Returns the value of cell group A. In case of LTC613: cell 1, 7 and 13
let voltages = client.read_voltages(CellSelection::Group1).unwrap();
assert_eq!(Channel::Cell1, voltages[0][0].channel);
assert_eq!(24979, voltages[0][0].voltage);

## State
> :warning: The crate is still incomplete, but is under active development.
> :warning: The crate has only been tested for the LTC6813 variant. Although the protocol of the LTC681X family is essentially the same, inconsistencies are still conceivable for some variants. Practical tests + feedback with other variants are therefore welcome.
