Detailed Description

Function Documentation

void waitMs

(

uint32_t

time_ms

)

Wait a given time in miliseconds.

Parameters

time_ms

Time to wait in miliseconds (in r0)

void writeLed	(	uint32_t	ledNr,
		uint32_t	ledState
	)

Turn a led on or off.

Parameters

ledNr	The selected led number (0 to 3) in register r0
ledState	The led status (0=off, else on) in register r1

void writeLedPwm	(	uint32_t	ledNr,
		uint32_t	ledLevel
	)

Set a led intensity.

Parameters

ledNr	The selected led number (0 to 3) in register r0
ledLevel	The led level (0=off to 100=100%) in register r1

uint32_t readButton

(

uint32_t

buttonNr

)

Read a button.

Parameters

buttonNr

The selected button number to read (0 to 3) in register r0

Returns

The button status in register r0 (0 = not pressed)

void decOut

(

uint32_t

value

)

Display a decimal value on the terminal.

Parameters

value

The value to display on the terminal in register r0

Use USE_STDIO_NOBUF 1 in config.h to print direclty the value on the serial port.

void hexOut

(

uint32_t

value

)

Display an hexadecimal value on the terminal.

Parameters

value

The value to display on the terminal in register r0

Use USE_STDIO_NOBUF 1 in config.h to print direclty the value on the serial port.

void strOut

(

uint8_t *

strPtr

)

Display a string on the terminal.

Parameters

strPtr

The string pointer in register r0

The string has to finish with a NULL character Use USE_STDIO_NOBUF 1 in config.h to print direclty the string on the serial port.

uint32_t decIn

(

void

)

Read a decimal value from the terminal.

Returns

The value read in register r0

The value has to finish with a CR character Use USE_STDIO_ECHO 1 in config.h to have an echo on the serial port when typing.

uint32_t hexIn

(

void

)

Read an hexadecimal value from the terminal.

Returns

The value read in register r0

The value has to finish with a CR character Use USE_STDIO_ECHO 1 in config.h to have an echo on the serial port when typing.

void strIn	(	uint8_t *	strPtr,
		uint32_t	maxLength
	)

Read a string from the terminal.

Parameters

strPtr	The string pointer in register r0
maxLength	The maximum string length in register r1

The string ends with a CR Use USE_STDIO_ECHO 1 in config.h to have an echo on the serial port when typing.
