Module-prefix MCU

Header file provides interfaces to set boot information, to disable/enable all interrupts, to wait a designated time and and to get the a timestamp based on the os systick.

Function Documentation

◆ MCU_CheckCRCUniqueDeviceID()

STD_RETURN_TYPE_e MCU_CheckCRCUniqueDeviceID ( uint8_t * dataptr )

Check if passed crc == unique device ID crc.

◆ MCU_DisableINT()

unsigned int MCU_DisableINT ( void )

disables interrupts and returns prior state (enabled or disabled)

this function is used for synchronization of real-time interrupts when bypassing FreeRTOS context and could be used (called) from 'interrupt blocked' or 'interrupt unblocked' context

Returns: current priority mask register, store this value and use it to enable interrupts again with CPU_RestoreINT()

◆ MCU_GetDeviceID()

void MCU_GetDeviceID ( MCU_DeviceID_s * deviceID )

Get unique device ID.

◆ MCU_GetTimeBase()

uint32_t MCU_GetTimeBase ( void )

gets systick value which is a 24-bit downcounter, auto refreshed with 71999

Returns: time current systick value

◆ MCU_RestoreINT()

void MCU_RestoreINT ( unsigned int primask_reg )

restores interrupts to given state (enable or disable)

this function is used for synchronization of real-time interrupts when bypassing FreeRTOS context

Parameters

primask_reg value for priority mask register, for use in case of nesting calling

◆ MCU_SystemResetStatus()

uint32_t MCU_SystemResetStatus ( uint32_t * regValue )

Gets system reset status.

Returns: 0: no unexpected reset detected, otherwise unexpected reset detected

◆ MCU_Wait_us()

void MCU_Wait_us ( uint32_t time )

simple wait-loop to wait short periods of time

Parameters

time	number of microseconds to wait, max. 1000us

Variable Documentation

◆ mcu_unique_deviceID

MCU_DeviceID_s mcu_unique_deviceID
