§ CreateChar()

void CreateChar	(	uint8_t	address,
		uint8_t	map[],
		uint8_t	display
	)

Used to redefine some custom characters. The char is the number of the character to redefine (0-7). Array is a 8bytes array with the bitmap of new character. sr is the number of the shift register.

address is the char you want to change (0-7) map is the buffer

Parameters

display is the number of register in the chain

byte MyChar[8] = {0,10,21,10,0,17,14,3}; 
My595.CreateChar(0,MyChar,3); 
My595.DisplayChar(0,3);

§ DirectdigitalWrite()

void DirectdigitalWrite	(	uint8_t	,
		uint8_t *	,
		uint8_t
	)

inline

§ DisplayChar()

void DisplayChar	(	uint8_t	buff,
		uint8_t	display
	)

Write a single char on the specificated display starting from actual position.

Parameters

buff	is the char to write display is the shift register number in the chain.

Definition at line 183 of file Ss_hc595.cpp.

§ DisplayReset()

void DisplayReset	(	uint8_t	options,
		uint8_t	num
	)

Reset of the display.

Parameters

options You can combite (with |) more of this:
LCD595_BASIC_DISPLAY_INIT: standard reset
LCD595_USEFONT_5X10: use the 5x10 font instead the 5x8
LCD595_MORELINES: use displays with more than one line.
If you leave a null value, the standard option is: LCD595_BASIC_DISPLAY_INIT | LCD595_USEFONT_5X10 | LCD595_MORELINES num is the number of shift register in the chain

Definition at line 143 of file Ss_hc595.cpp.

§ DisplayWrite()

void DisplayWrite	(	const char *	buff,
		uint8_t	display
	)

Write a string on the specificated display starting from actual position.

Parameters

buff	is the buffer to write (null terminated!) display is the shift register number in the chain.

Definition at line 173 of file Ss_hc595.cpp.

§ Lcd_SetFreePin()

void Lcd_SetFreePin	(	uint8_t	pin,
		bool	status,
		uint8_t	sr
	)

Sets the free pins (2 and 0) of 74HC595 connected to a display. ,.

Parameters

pin	is the pin (0 or 2) status is the state (HIGH o LOW)
sr	and sr is the shift register number (from 0).

Here is the caller graph for this function:

§ Send595Pin()

void Send595Pin	(	uint8_t	val,
		uint8_t	display
	)

It works as the sum of Set595Pin and the Send595, in the sense that sets the 8-bit and sends them directly to the shift register. If you have only one shift register to edit you should use this function. If you need to change more than one at the same time you should use two or more Set595 and eventually Send595 at the end.

Parameters

val	is the 8 bit buffer to fill relative 74HC595
display	is the number of shift register on the chain (0 is the first!).

§ SendLcdCommand()

void SendLcdCommand	(	uint8_t	val,
		uint8_t	display
	)

This function is useful to send directly some commands to the display. val This is the option parameter which is a char in which every bit will be sent to the display. There are some pre-set:
LCD595_DISPLAY_ON_CB: Switch on the display with blinking cursor on.
LCD595_DISPLAY_ON_C: Switch on the display with NOT blinking cursor.
LCD595_DISPLAY_ON_B: Switch on the display with last char blinking.
LCD595_DISPLAY_ON: Switch on display without cursor.
LCD595_DISPLAY_OFF: Switch off the display
LCD595_DISPLAY_CLEAR: Cleans the display.

display is the shift register number on the chain
