Crate ltc681x

Generic client for LTC681X battery stack monitors

Supports all devices of LTC681X family: LTC6813, LTC6812, LTC6811 and LTC6810.

Currently the following features are implemented:

• Cell and GPIO conversion
• Reading cell and GPIO voltage registers
• Multiple devices in daisy chain
• ADC status polling (SDO line method)
• Mapping voltages to GPIO and cell groups
• Abstracted device configuration
• Overlapping ADC measurement
• Internal device parameters measurement

Example

For all details see monitor module.

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);
