LCDIN {Address,}[Var{,Var...}]
Read LCD RAM at Address and store data to Var. LCDs have RAM onboard that is used for character memory. Most LCDs have more RAM available that is necessary for the displayable area. This RAM can be written using the LCDOUT instruction. The LCDIN instruction allows this RAM to be read. CG (character generator) RAM runs from address $40 to $7f. Display data RAM starts at address $80. See the data sheet for the specific LCD for these addresses and functions. It is necessary to connect the LCD read/write line to a PICmicro pin so that it may be controlled to select either a read (LCDIN) or write (LCDOUT) operation. Two DEFINEs control the pin address:
Code:
DEFINE LCD_RWREG PORTE ' LCD read/write pin port
DEFINE LCD_RWBIT 2 ' LCD read/write pin bit
