Prefix: MXM

This file contains that part of the state machine that is executed during the operation state. It is adapted for MAX17852.

Definition in file mxm_17852.c.

Macro Definition Documentation

◆ MXM_DELAY_BALANCING

#define MXM_DELAY_BALANCING 10000u

Delay in milliseconds before the balancing status is updated.

Definition at line 80 of file mxm_17852.c.

Function Documentation

◆ MXM_GetModelIdOfDaisyChain()

MXM_MODEL_ID_e MXM_GetModelIdOfDaisyChain ( void )

returns the model ID of the daisy chain

this function is to be implemented by the driver in order to tell the rest of the driver which model is used. Currently, this implementation does not support mixed model daisy-chains.

Returns: model ID of daisy-chain

Definition at line 91 of file mxm_17852.c.

◆ MXM_StateMachineOperation()

void MXM_StateMachineOperation ( MXM_MONITORING_INSTANCE_s * pState )

State-Machine implementation for operation state.

This state-machine contains the "program" with which the connected monitoring satellites are controlled. It is entered by MXM_StateMachine() once the daisy-chain has been initialized and is in operation state.

Parameters

[in,out] pState used as both input and output (stores state-information, requests and intermediate values)

Mapping of voltage registers

This array maps registers of the monitoring IC onto cell-numbers. The register values are defined in the MXM_REG_NAME_e enum. For now the length of this array is MXM_VOLTAGE_READ_ARRAY_LENGTH as it is enabled for the measurement of all cells, two AUX-voltages and one block voltage. This has to be adapted once this driver is enabled for general operation.
