Function Documentation

◆ hexstr_to_uint()

uint32_t hexstr_to_uint	(	char *	buffer,
		uint8_t	length )

Helper function to convert N hex char string into uint32_t.

Parameters

[in]	buffer	Pointer to array of chars to convert into number.
[in]	length	Length of the conversion string.

Returns: Converted 32-bit number.

◆ main()

int main ( void )

Main function

Note: This program requires the ONEWIRE and UART0 modules. Only non-blocking ONEWIRE functions are used.

Returns: !=0 if setup error

◆ read_byte()

void read_byte ( void )

Read full byte from bus.

◆ scan_bus()

void scan_bus ( void )

Scan bus for devices and print IDs.

◆ show_1wire_commands()

void show_1wire_commands ( void )

Show standard 1-wire commands.

◆ show_help()

void show_help ( void )

Show help menu.

◆ write_byte()

void write_byte ( void )

Write full byte to bus.
