clearing the LCD

hey guys,

i have a small problem clearing the LCD in a "state machine" type of program. the microcontroller i am using is the pic24f and i am programming in C.

i want to display the state of the machine on the lcd, and when it changes i want to clear the LCD and display the new state, and so on..

how would i go about this?

i am using this lcd.c file made by microchip. that has functions like

LCDInit()
LCDHome()
LCDL1Home()
LCDL2Home()
LCDClear()
LCDPut()
 

clearing the LCD

Don't know about this particular driver, but I have found in a lot of cases you need to send a string of non printable characters, usually spaces. So if it is a 16 digit display, home the cursor and then print 16 spaces, followed by home the cursor again, ready to write new data. May not of course work in your case, but worth a try.
