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.

CC_DISPLAY_STR

1 2 ... 143 144 145 146 147 148 149 150 151 152 153 ... 311 312
