Prefix: LED

This module controls the debug LED that is directly connected to a MCU pin. It is used to indicate basic operation states.

During startup the LED is enabled continuously.
Once the startup is complete the LED should be called with LED_SetToggleTime() in order to indicate whether the BMS has started normal operation (LED_NORMAL_OPERATION_ON_OFF_TIME_ms, slow blinking pattern) or if it is in an error state (LED_ERROR_OPERATION_ON_OFF_TIME_ms, fast blinking pattern).
LED_SetToggleTime() can be called anytime the indicated pattern shall change.

Macro Definition Documentation

◆ LED_ERROR_OPERATION_ON_OFF_TIME_ms

#define LED_ERROR_OPERATION_ON_OFF_TIME_ms (100u)

time span to be used with LED_SetToggleTime() indicating an error state

Definition at line 76 of file led.h.

◆ LED_NORMAL_OPERATION_ON_OFF_TIME_ms

#define LED_NORMAL_OPERATION_ON_OFF_TIME_ms (500u)

time span to be used with LED_SetToggleTime() indicating normal operation

Definition at line 74 of file led.h.

Function Documentation

◆ LED_SetDebugLed()

void LED_SetDebugLed ( void )

Turn debug LED on.

This function is intended to be called once during startup before LED_SetToggleTime() is called (after startup).

Definition at line 87 of file led.c.

Here is the call graph for this function:

◆ LED_SetToggleTime()

void LED_SetToggleTime ( uint32_t onOffTime_ms )

Set debug LED with defined frequency.

Parameters

onOffTime_ms requested time for ON/OFF duration in ms

Definition at line 114 of file led.c.

◆ LED_Trigger()

void LED_Trigger ( void )

Trigger function to periodically toggle debug LED. Frequency can be set via function LED_SetToggleTime()

Definition at line 91 of file led.c.

Here is the call graph for this function:

◆ TEST_LED_GetOnOffTime()

uint32_t TEST_LED_GetOnOffTime ( void )

Definition at line 122 of file led.c.

◆ TEST_LED_SetOnOffTime()

void TEST_LED_SetOnOffTime ( uint32_t val )

Definition at line 125 of file led.c.
