Detailed Description

Functions for receiving and sending with USART.

Function Documentation

ISR ( USART0_RX_vect )

USART0 Receive interrupt. Occurs every time a character is received in USART0.

Here is the call graph for this function:

ISR ( USART1_RX_vect )

USART1 Receive interrupt. Occurs every time a character is received in USART1.

Warning: The USART1 receive interrupt is disabled.

Todo:: this counter doesn't work

warning USART1:stä ei voida ottaa merkkejä vastaan samaan puskuriin, muutettu receive buffer Debugbufferiksi

ISR ( USART1_TX_vect )

USART1 transmit interrupt.

Warning: The USART1 transmit interrupt is disabled.

void USART0_init ( void )

Initialization of USART0. USART0 settings 7 data, 1 stop bit, No parity. USART0 is used for ModBus communication.

< write high register first

< ((XTAL/16)/BAUD)-1;

Here is the caller graph for this function:

void USART0_Transmit ( unsigned char character )

Sends a character from USART0.

Parameters

character Character to be sended from USART0.

Todo:: No delay should be in this function.

Warning: If buffer is not ready, function will wait for its clearence, waists time.

Warning: Must get rid off delay

Todo:: Must get rid off delay

Here is the call graph for this function:

Here is the caller graph for this function:

void USART0_Transmit_string ( unsigned char * string )

Sends a string from USART0.

Parameters

string Pointer to string to be sended from USART.

Warning: EOL '\0' character is expected to be at the end of string.; Should NOT be used for ModBus communication.

Here is the call graph for this function:

void USART1_init ( void )

Initialization of USART1.

Warning: tällä ei mitään merkitystä, seuraavaksi kirjoitetaan sen yli

Here is the caller graph for this function:

void USART1_int_Transmit_string ( unsigned char * string_to_be_sent )

Transmit one character with interrupt.

Parameters

string_to_be_sent Pointer to the string to be sent.

Warning: The USART1 transmit interrupt is disabled.

void USART1_Transmit ( unsigned char character )

Send one character from USART1.

Parameters

character Character to be sended from USART.

Warning: If buffer is not ready, function will wait for its clearence, waists time.
