CCPU_SetDotMatrixLED
Sets values to be displayed on the dot matrix LED of a MELIPC.
Format
short CCPU_SetDotMatrixLED(unsigned short usMode, char* pcData)
Argument
Argument
usMode
pcData
• Specifies the LED data (pcData) as follows when the output mode (usMode) is '0' (dot mode).
pcData[1]
pcData[0]
pcData[0] to pcData[79]: Data on the dot matrix LED (9×40)
The following table shows the specified data in the following formats.
pcData
pcData [even number]
pcData [odd number]
When the corresponding bit of the bit pattern section is '1', the LED turns ON.
Ex.
When the following bit pattern is displayed on the dot matrix LED
1 5

Description
The lower seven bits are all specified to '0'.
The upper 1 bit specifies the bit pattern corresponding to line 9 of the dot matrix LED.
Specifies the bit pattern corresponding to lines 1 through 8 of the dot matrix LED. (The most significant bit corresponds
to line 1)
Description
Specify the output mode to the dot matrix LED.
(When 'Reserved' is specified, this function ends normally without
processing.)
• 0: Dot mode
