Function Documentation

dbAlert()

void dbAlert

(

void

)

Sound an alert in the terminal.

Print the bell (alert) character to USARTx.

Definition at line 344 of file dbprint.c.

{
    USART_Tx(dbpointer, '\a');
}

dbClear()

void dbClear

(

void

)

Clear the terminal.

Print the form feed character to USARTx. Accessing old data is still possible by scrolling up in the serial port program.

Definition at line 358 of file dbprint.c.

{
    USART_Tx(dbpointer, '\f');
}

dbcrit()

void dbcrit

(

char *

message

)

Print a critical error string (char array) in red to USARTx and go to the next line.

Note

If the input is not a string (ex.: "Hello world!") but a char array, the input message (array) needs to end with NULL ("\0")!

Parameters

[in]

message

The string to print to USARTx.

Definition at line 541 of file dbprint.c.

{
    dbprint_color("CRIT: ", RED);
    dbprintln_color(message, RED);
}

dbcritInt()

void dbcritInt	(	char *	message1,
		int32_t	value,
		char *	message2
	)

Print a critical value surrounded by two strings (char array) to USARTx.

"CRIT: " gets added in front, the decimal notation is used and the function advances to the next line. The value is in the color white, the rest is red.

Note

If the input is not a string (ex.: "Hello world!") but a char array, the input message (array) needs to end with NULL ("\0")!

Parameters

[in]	message1	The first part of the string to print to USARTx.
[in]	value	The value to print between the two string parts.
[in]	message2	The second part of the string to print to USARTx.

Definition at line 631 of file dbprint.c.

{
    dbprint_color("CRIT: ", RED);
    dbprint_color(message1, RED);
    dbprintInt(value);
    dbprintln_color(message2, RED);
}

dbcritInt_hex()

void dbcritInt_hex	(	char *	message1,
		int32_t	value,
		char *	message2
	)

Print a critical value surrounded by two strings (char array) to USARTx.

"CRIT: " gets added in front, the hexadecimal notation is used and the function advances to the next line. The value is in the color white, the rest is red.

Note

If the input is not a string (ex.: "Hello world!") but a char array, the input message (array) needs to end with NULL ("\0")!

Parameters

[in]	message1	The first part of the string to print to USARTx.
[in]	value	The value to print between the two string parts.
[in]	message2	The second part of the string to print to USARTx.

Definition at line 723 of file dbprint.c.

    dbprintln_color(message2, RED);
}

dbGet_RXbuffer()

void dbGet_RXbuffer

(

char *

buf

)

Get the value of the RX buffer and clear the dataReceived flag.

Note

The index of the RX buffer gets reset in the RX handler when a CR character is received or the buffer is filled.

Attention

Interrupt functionality has to be enabled on initialization for this function to work correctly.

Parameters

[in]

buf

The buffer to put the resulting string in. This needs to have a length of DBPRINT_BUFFER_SIZE for the function to work properly: char buf[DBPRINT_BUFFER_SIZE];!

Definition at line 1019 of file dbprint.c.

{
    if (dataReceived)
    {
        uint32_t i;

        /* Copy data from the RX buffer to the given buffer */
        for (i = 0; rx_buffer[i] != 0 && i < DBPRINT_BUFFER_SIZE-1; i++)
        {
            buf[i] = rx_buffer[i];
        }

        /* Add NULL termination character */
        buf[i++] = '\0';

        /* Reset "notification" variable */
        dataReceived = false;
    }
    else
    {
        dbcrit("No received data available!");
    }
}

dbGet_RXstatus()

bool dbGet_RXstatus

(

void

)

Check if data was received using interrupts in the RX buffer.

Note

The index of the RX buffer gets reset in the RX handler when a CR character is received or the buffer is filled.

Attention

Interrupt functionality has to be enabled on initialization for this function to work correctly.

Returns

• true - Data is received in the RX buffer.
• false - No data is received.

Definition at line 911 of file dbprint.c.

{
    return (dataReceived);
}

    {
        USART_Tx(dbpointer, message[i]);

	)

Print a string (char array) to USARTx in a given color and go to the next line.

Note

If the input is not a string (ex.: "Hello world!") but a char array, the input message (array) needs to end with NULL ("\0")!

Parameters

[in]	message	The string to print to USARTx.
[in]	color	The color to print the text in.

Definition at line 482 of file dbprint.c.

{
    dbprint_color(message, color);

(

int32_t

value

)

Print a number in decimal notation to USARTx and go to the next line.

Parameters

[in]

value

The number to print to USARTx. This can be of type uint32_t or int32_t.

Definition at line 776 of file dbprint.c.

{
    dbprintInt(value);

    /* Carriage return */
    USART_Tx(dbpointer, '\r');

    /* Line feed (new line) */
    USART_Tx(dbpointer, '\n');
}

dbprintlnInt_hex()

void dbprintlnInt_hex

(

int32_t

value

)

Print a number in hexadecimal notation to USARTx and go to the next line.

Parameters

[in]

value

The number to print to USARTx. This can be of type uint32_t or int32_t.

Definition at line 813 of file dbprint.c.

{
    dbprintInt_hex(value);

    /* Carriage return */
    USART_Tx(dbpointer, '\r');

    /* Line feed (new line) */
    USART_Tx(dbpointer, '\n');
}

dbReadChar()

char dbReadChar

(

void

)

Read a character from USARTx.

Returns

The character read from USARTx.

Definition at line 832 of file dbprint.c.

{
    return (USART_Rx(dbpointer));
}

dbReadInt()

uint8_t dbReadInt

(

void

)

Read a decimal character from USARTx and convert it to a uint8_t value.

Note

Specific methods exist to read uint16_t and uint32_t values:

• uint16_t USART_RxDouble(USART_TypeDef *usart);
• uint32_t USART_RxDoubleExt(USART_TypeDef *usart);

Returns

The converted uint8_t value.

Definition at line 850 of file dbprint.c.

{
    /* Method expects a char array ending with a null termination character */
    char value[2];
    value[0]= dbReadChar();
    value[1] = '\0';

    return (charDec_to_uint32(value));
}

dbReadLine()

void dbReadLine

(

char *

buf

)

Read a string (char array) from USARTx.

Note

The reading stops when a "CR" (Carriage Return, ENTER) character is received or the maximum length (DBPRINT_BUFFER_SIZE) is reached.

Parameters

[in]

buf

The buffer to put the resulting string in. This needs to have a length of DBPRINT_BUFFER_SIZE for the function to work properly: char buf[DBPRINT_BUFFER_SIZE];!

Definition at line 874 of file dbprint.c.

{
    for (uint32_t i = 0; i < DBPRINT_BUFFER_SIZE - 1 ; i++ )
    {
        char localBuffer = USART_Rx(dbpointer);

        /* Check if a CR character is received */
        if (localBuffer == '\r')
        {
            /* End with a null termination character, expected by the dbprintln method */
            buf[i] = '\0';
            break;
        }
        else
        {
            buf[i] = localBuffer;
        }
    }
}

dbwarn()

void dbwarn

(

char *

message

)

Print a warning string (char array) in yellow to USARTx and go to the next line.

Note

If the input is not a string (ex.: "Hello world!") but a char array, the input message (array) needs to end with NULL ("\0")!

Parameters

[in]

message

The string to print to USARTx.

Definition at line 523 of file dbprint.c.

{
    dbprint_color("WARN: ", YELLOW);
    dbprintln_color(message, YELLOW);
}

dbwarnInt()

void dbwarnInt	(	char *	message1,
		int32_t	value,
		char *	message2
	)

Print a warning value surrounded by two strings (char array) to USARTx.

"WARN: " gets added in front, the decimal notation is used and the function advances to the next line. The value is in the color white, the rest is yellow.

Note

If the input is not a string (ex.: "Hello world!") but a char array, the input message (array) needs to end with NULL ("\0")!

Parameters

[in]	message1	The first part of the string to print to USARTx.
[in]	value	The value to print between the two string parts.
[in]	message2	The second part of the string to print to USARTx.

Definition at line 600 of file dbprint.c.

{
    dbprint_color("WARN: ", YELLOW);
    dbprint_color(message1, YELLOW);
    dbprintInt(value);
    dbprintln_color(message2, YELLOW);
}

dbwarnInt_hex()

void dbwarnInt_hex	(	char *	message1,
		int32_t	value,
		char *	message2
	)

Print a warning value surrounded by two strings (char array) to USARTx.

"WARN: " gets added in front, the hexadecimal notation is used and the function advances to the next line. The value is in the color white, the rest is yellow.

Note

If the input is not a string (ex.: "Hello world!") but a char array, the input message (array) needs to end with NULL ("\0")!

Parameters

[in]	message1	The first part of the string to print to USARTx.
[in]	value	The value to print between the two string parts.
[in]	message2	The second part of the string to print to USARTx.
