NOTE Make certain the RS-232 cable includes the required ground lead. There must be no voltage differential between the RS-232 ground and the power supply ground. 4. Connect the power connector, making sure that the +5V goes to V+. Turn on the power: the display backlight should come on. Matrix Orbital PK162-12... -

Matrix Orbital module processes data. Basically, the reason why a Matrix Orbital module might fail to receive a byte correctly is that it was unable to process the byte previous before the failed byte was transmitted. Because the module cannot possibly know that it would be unable to store the byte before the next byte was received it cannot know to not ACK. -

/ write bit. If we take a standard Phillips 7bit address of 45hex this would be in binary 1000101. This is 7bits. Matrix Orbital would describe the Phillips I C address of 45hex as 8Ahex. The read address would be 8Bhex. -

3.1 General Text is displayed on the PK162-12 using the built in 5x8 dot matrix font, in addition to up to 8 user defined characters. 3.2 The built in Character Font The display includes a built in 5x8 dot matrix font with the full range of ASCII characters plus a variety of extended characters. -
Page 18: Writing Text To The Display
When auto scrolling is disabled, text will wrap to the top left corner of the display area. Existing text in the display area is not erased before new text is placed. A series of ’spaces’ followed by a “Cursor home” command may be used to erase the top line of text. Matrix Orbital PK162-12... -

Note that this command moves the text insertion point even if the cursor is turned off. NOTE A ’destructive backspace’, which erases the character to the left of the original position, may be done by issuing the following sequence: cursor left, space, cursor left. Matrix Orbital PK162-12... -

first read will return the key code with bit 7 set and the second read will return the key code with bit 7 clear. The application must take into account this bit to keep up with user key presses. If there are no keypresses detected, the module will return zero (0x00). Matrix Orbital PK162-12... -

If the poll rate is slower than the simulated auto - repeat it is possible that polling for a key up code will be delayed long enough for an unwanted key repeat to be generated. 4.5.2 Auto Repeat Mode Off (254 96) (R) This command turns auto repeat mode off. Matrix Orbital PK162-12... -

This command defines the 8 special / user characters to be blocks suitable for use in drawing narrow (2 pixel) vertical bar graphs. Any previously existing definitions will be lost. Once this command has been issued, any number of vertical bar graphs may be drawn unless the characters are redefined by another command. Matrix Orbital PK162-12... -

A "1" bit indicates an on (black) pixel, a "0" bit indicates an off (clear) pixel. Once defined, a character is displayed simply by issuing a value (0x00 to 0x07) corresponding to the character number.
