Description
Use the CC_DISPLAY_STR function to display a 4 character string on the
optional ASCII display.
Important: ASCII display remains unchanged until another display
function call is performed successfully.
CC_DISPLAY_STR looks at the string as a four-character buffer.
Therefore, it is not necessary to include a null character as a terminator.
Likewise, any null character occurring within the four-character buffer
will be displayed.
