MIAC (PIC) component
MIAC - Matrix Industrial Automotive Controller PLC type module based on a PIC18F4455 device, produced by Matrix Component includes functions to drive the functionality of the MIAC and MIAC system.
Examples
Analogue Input
Basic example of how to read an analogue input on the MIAC and display it on the LCD.
MIAC ADC LCD
Keypad Input
Basic example of how to read the keypad and display the value on the LCD.
MIAC Keypad
For reference the numbering of the MIAC keypad looks like this.
Output Control
Basic example of how to control all of the individual outputs on the MIAC using the keypad.
Note that for the transistor outputs to come on you must wire a connection from the +V terminal to the M terminal.
If you are driving high current outputs then you can instead supply separate DC power to the M terminal.
MIAC Outputs
MIAC Interrupt Controlled Clock
Basic example of how to create a timer interrupt based clock.

InputANALOG_10Bit
Returns the 10 bit value for the analogue input requested by parameter InputID
(Inputs 1 to 8)
Parameters
- BYTE InputID
- The input to read from 1 to 8.
Return value
RelayOFF
Turns off the requested relay given by parameter RelayID, values 1 to 4
Parameters
- BYTE RelayID
- The relay to turn off. From 1 to 4.
Return value
- This call does not return a value
PrintString
Prints the given character string to the display at the current cursor position and moves the cursor position.
Parameters
- <- STRING Str
- The string to send to the display.
- This parameter may be returned back to the caller
Return value
- This call does not return a value
GetKeypad

Return value
DisplayStart
Initialise the display ready for use
Parameters
- This macro has no parameters
Return value
- This call does not return a value
DisplayCommand
Sends the given command to the display
Parameters
