Code:
glcd_fs var LATD.0 ' Font Select pin High = 6x8 , Low = 8x8
glcd_wr var LATD.1 ' Write control pin ( Active Low)
glcd_rd var LATD.2 ' Read control bit ( Active Low)
glcd_ce var LATD.3 ' Chip enable control bit ( Active Low)
glcd_cd var LATD.4 ' Command (high) and Data (low) toggle bit
glcd_rst var LATD.5 ' Reset control bit (Active Low)
glcd_tris var TRISE ' Data bus direction
glcd_dat var PORTE ' LCD 8 bit data bus
glcd_sta0 var PORTE.0 ' Status Bit 0 - Status Read - Command excute capability - 0 = not avaialble / 1 = Available
glcd_sta1 var PORTE.1 ' Status Bit 1 - Status Read - Data Read/Write capability - 0 = not avaialble / 1 = Available
yes the 8 bits of the port are used as both input / output
i would think PBP uses the LAT registers in the above use ???
i um PBP uses the LAT
