Combo (BL0114) component
A component to drive the BL0114 Combo board including LEDs, Switches, LCD, 7-Segs and analogue inputs.
Make sure both bank 0 and bank 1 are connected to the right ports in flowcode, which correspond to the ports the combo board is connected to on your E-blocks 2 upstream board. There are lots of component macros in flowcode 8, which you can use to read the input from one of the analog devices (potentiometer/LDR) as a byte or an integer, as well as doing many things with the LCD such as printing numbers, strings, formatted numbers or a character which corresponds to an inputted ascii value. There is also a component macro you can use to show a digit on one of the 7-segment displays. On the combo board there are also 16 switches and 16 LEDs, and in flowcode 8 there are component macros which can be used to read the state of a specified switch, or to set the state of a specified LED on the board. Before you can display anything on the LCD screen you must first put the ‘LCD_Start’ macro into the program.

Seg_ShowDigit
Displays a digit on the 7-seg display
Parameters
- BYTE Digit
- Which of the digits to change (0 - 3)
- BYTE Value
- The value to display (0 - 9)
- BYTE DecimalPoint
- Decides if the decimal point is lit
Return value
- This call does not return a value
LCD_PrintFormattedNumber
Will allow you to print a number up to 32-bits with signed or unsigned formatting.
Signed = -2147483648 to 2147483647
Unsigned = 0 to 4294967295
Parameters
- ULONG Number
- Enter the number or variable to print to the LCD
- BOOL Format
- 0=Signed, 1=Unsigned
Return value
- This call does not return a value
LCD_RemapCharacter
Assigns a remap character allowing the PrintString function to automatically swap between pre-defined characters.
The characters can be custom (in the range 0-9) or can point to an existing character in the LCD character map.
Parameters
- BYTE RemapIdx
- Remap Index, Range: 0 to (Remap Characters - 1)
- BYTE SearchCharacter
- Character to look for a replace
- BYTE ReplacementCharacter
- New character value to use in place of the search character.
Return value
- This call does not return a value
LCD_ScrollDisplay
Scrolls the display left or right by a number of given positions.
Parameters
- BYTE Position
- Holds the number of positions to shift the display
- BYTE Direction
- 0 = left, 1 = right
Return value
- This call does not return a value
IO_SetPort
Sets the state of a single port
Parameters
- BYTE Bank
- 0 = Top Bank of LEDs, 1 = Bottom Bank of LEDs
- BYTE Value
Return value
- This call does not return a value
IO_SetLEDState
Sets the state of a single LED
Parameters
- BYTE Bank
- 0 = Top Bank of LEDs, 1 = Bottom Bank of LEDs
- BYTE LED
- 0 = LED0, 7 = LED7
- BYTE State
- 0 = Off, 1 = On
Return value
- This call does not return a value
IO_GetPort
Reads the state of a single port
Parameters
- BYTE Bank
- 0 = Top Bank of Switches, 1 = Bottom Bank of Switches
Return value
LCD_Cursor
Moves the cursor on the LCD Display
Parameters
- BYTE x
- Set the cursor position in the X plane, 0 is the left most cell
- BYTE y
- Set the cursor position in the Y plane, 0 is the top most cell
Return value
- This call does not return a value
LCD_Start
Startup routine required by the hardware device.
Automatically clears the display after initialising.
Parameters
- This macro has no parameters
Return value
- This call does not return a value
LCD_Command
Use this method/macro to send a specific command to the LCD. Refer to the Matrix Multimedia EB006 datasheet for a list of supported instructions. For Non-Matrix LCD's refer to the manufacturers datasheet.
Parameters
- BYTE instruction
- Send a defined command to the LCD Screen. See datasheet for supported commands.
Return value
- This call does not return a value
LCD_RAMWrite
Modifies the internal memory of the LCD to allow for up to 8 customised characters to be created and stored in the device memory
Parameters
- BYTE Index
- Values 0 to 7
- BYTE d0
- BYTE d1
- BYTE d2
- BYTE d3
- BYTE d4
- BYTE d5
- BYTE d6
- BYTE d7
Return value
- This call does not return a value
IO_ReadAnalogAsInt
Reads one of the analogue components as an Integer value
Parameters
- BYTE Channel
- 0 = Light Sensor, 1 = Potentiometer
Return value
LCD_PrintString
Breaks down a string of text and sends it to the LCD via the private RawSend(byte, mask) macro
Parameters
- <- STRING Text
- Enter the text or variable to print to the LCD
- This parameter may be returned back to the caller
Return value
- This call does not return a value
LCD_ClearLine
Clears a single line on the display and then moves the cursor to the start of the line to allow you to start populating the line with data.
Parameters
- BYTE Line
- The line to clear, zero being the first (top) line of the display
Return value
- This call does not return a value
IO_GetSwitchState
Reads the state of a single switch
Returns: 0 = Switch not pressed, 1 = Switch pressed
Parameters
- BYTE Bank
- 0 = Top Bank of Switches, 1 = Bottom Bank of Switches
- BYTE Switch
- 0 = SW0, 7 = SW7
Return value
IO_ReadAnalogAsByte
Reads one of the analogue components as an byte value
Parameters
- BYTE Channel
- 0 = Light Sensor, 1 = Potentiometer
Return value
LCD_PrintAscii
Takes the ascii value for a character and prints the character
Parameters
- BYTE character
- Holds an ascii value.
Return value
- This call does not return a value
LCD_PrintNumber
Based on v5 macro, will allow you to print a number. This is limited to a signed-INT, -32768 to 32767
Parameters
- INT Number
