Trait Implementations

`impl GsEps for Eps`[src][+]

`fn new(bus: &str, addr: u8) -> EpsResult<Eps>`[src][−]

Constructor

Opens a connection to the underlying I2C device

Arguments

bus - The I2C bus to use to communicate with the device
I2C_addr - The I2C address of the EPS, Default 0x08
WD_timeout - The watchdog timeout interval, in seconds

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn ping(&self) -> EpsResult<()>`[src][−]

Ping the EPS. Send a cmd (1) to the eps. Expect the same command returned by the EPS

`fn reset(&self) -> EpsResult<()>`[src][−]

Hard reset the EPS's microcontrollers

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn reboot(&self) -> EpsResult<()>`[src][−]

Soft reset the EPS's microcontrollers

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn configure_system(&self, config: EpsSystemConfig) -> EpsResult<()>`[src][−]

System Configuration (conf)

Set the system configuration

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn configure_battery(&self, config: EpsBatteryConfig) -> EpsResult<()>`[src][−]

Battery Configuration (conf2)

Set the battery configuration

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn save_battery_config(&self) -> EpsResult<()>`[src][−]

Save Battery Configuration

Save the battery configuration, must be done after battery configuration or it will fall back after a while

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn set_output(&self, channel_mask: u8) -> EpsResult<()>`[src][−]

Batch set EPS output

Set output switch states by a bitmask where "1" means the channel is switched on and "0" means it is switched off. LSB is channel 1, next bit is channel 2 etc. (Quadbat switch and heater cannot be controlled through this command) [NC NC 3.3V3 3.3V2 3.3V1 5V3 5V2 5V1]

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn set_single_output( &self, channel: EpsChannels, value: EpsPowerState, delay: u16 ) -> EpsResult<()>`[src][−]

Set single EPS output

Set output %channel% to value %value% with delay %delay%, Channel (0-5), Quadbat heater (6), Quadbat switch (7) Value 0 = Off, 1 = On Delay in seconds.

Example: set_single_output(0, 1, 0) This will set channel 0 to be ON with no delay

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn set_input_value( &self, in1_voltage: u16, in2_voltage: u16, in3_voltage: u16 ) -> EpsResult<()>`[src][−]

Set the MPPT value for each channel

Set the voltage on the photo-voltaic inputs V1, V2, V3 in mV. Takes effect when MODE = 2, See SET_PV_AUTO. Transmit voltage1 first and voltage3 last.

The voltage needs to changed to align with the number of solar panels you have on each channel

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn set_input_mode(&self, mode: u8) -> EpsResult<()>`[src][−]

Set the MPPT mode

Sets the solar cell power tracking mode: MODE = 0: Hardware default power point MODE = 1: Maximum power point tracking MODE = 2: Fixed software powerpoint, value set with SET_PV_VOLT, default 4V

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn set_heater(&self, heater: HeaterSelect, mode: EpsPowerState) -> EpsResult<()>`[src][−]

Set heater ON/OFF

Cmd = 0: Set heater on/off Heater: 0 = BP4, 1= Onboard, 2 = Both Mode: 0 = OFF, 1 = ON

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn reset_system_config(&self) -> EpsResult<()>`[src][−]

Reset the EPS configuration to default

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn reset_battery_config(&self) -> EpsResult<()>`[src][−]

Reset the Battery configuration to default

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn reset_counters(&self) -> EpsResult<()>`[src][−]

Reset boot counter and WDT counters (excluding the dedicated WDT)

Errors

If this function encounters any errors, an [EpsError] variant will be returned.

`fn get_housekeeping(&self) -> EpsResult<EpsHk>`[src][−]
