Detailed Description

Message processing implementation

Contains the defines to initialize the CAN port with the apropiate parameters, and other defines needed in the aplication.

Enumeration Type Documentation

MACHINE_SERIAL

enum MACHINE_SERIAL

Enum with states for state machines.

Enumerator
SERIAL_TIME	Clock machine state for set alarm
SERIAL_DATE	Clock machine state for set date
SERIAL_ALARM	Clock machine state for set time
SERIAL_OK	Clock machine state for set print
SERIAL_ERROR	Clock machine state for set print
SERIAL_IDLE	Clock machine state idle

Function Documentation

Serial_Init()

void Serial_Init ( void )

extern

Initialize of CAN port

Is the function to initialize all the required to start working with the CAN port and the messages reception processing

Note

Declaration of the options to configure the FDCAN1 module to transmit to the CAN bus at 100Kbps and sample point of 75%, the frequency with which the CAN module is powered is fCAN = fHSI / CANHandler.Init.ClockDivider / CANHandler.Init.NominalPrescaler fCAN = 32MHz / 1 / 8 = 4MHz The number of time quantas required is Ntq = fCAN / CANbaudrate Ntq = 4MHz / 250Kbps = 16 The sample point percentage is Sp = ( CANHandler.Init.NominalTimeSeg1 + 1 / Ntq ) * 100 Sp = ( ( 11 + 1 ) / 16 ) * 100 = 75%

Call of the serial state machine

This function calls the serial state machine every 10ms with the help of queues, therefore it won't be execute all the time
