Created page with "= Action = Override the LCD-PIN select options. </span..."

New page

Override the LCD-PIN select options.

CONFIG LCDPIN = PIN , DB4= PN,DB5=PN, DB6=PN, DB7=PN, E=PN, RS=PN  [WR=PIN] [BUSY=PIN] [MODE=mode]

When you want to use the LCD in 8 bit data, pin mode, you must specify the PORT to use.

PIN

| valign="top" width="100%" style="width: 502px; border: 1px solid rgb(0, 0, 0);" |
A port pin that is connected to the busy pin. The busy pin is only supported by the 20x4VFD display.

|- style="vertical-align: top;"
| valign="top" width="16%" style="width: 93px; border: 1px solid rgb(0, 0, 0);" |
MODE

| valign="top" width="100%" style="width: 502px; border: 1px solid rgb(0, 0, 0);" |
A mode for the 20x4VFD display. Options :

0 : 4 bit parallel upper nibble first

1 : 4 bit parallel lower nibble first

|}
</div>
 

You can override the PIN selection from the Compiler Settings with this statement, so a second configuration lets you not choose more pins for a second LCD display.

 

The config command is preferred over the option settings since the code makes clear which pins are used. The CONFIG statement overrides the Options setting.

 

The PIN and MODE are only for the 20x4VFD display. See also [[LCDAUTODIM]]

 

The WR pin is optional. When you select the WR pin, an alternative library will be used. This library uses the WR pin and reads the BUSY signal from the LCD.

The library lcd4busy_anypin will be used, which is based on Luciano's LUC_lcd4busy library.

Notice that since 2040 version, the compiler will generate LCD port pin info which you can use for your own libs.

 

By default the WR pin is optional and the WR signal of the LCD should be connected to ground. This saves the pin for other purposes. When you have enough pins, you better use the WR-pin.

If you do not connect the WR pin to ground but to a pin, and you do not specify the WR pin, but you set the logic level to 0 in your code, you have to use an INITLCD command after you have set the WR pin to 0.
