to assemble a entire circuit using a ZIF socket and LCD for 8535 takes under 12 hours. which I call as expert. :P. the assemble is sets RS/RW/E pins on first three pins of Port C while data on port B. The plan was to free my ADC on port A and and UART pins on port D which left me with port B and port C. port C still has space for clock crystal. the possible bad news is by MISO and MOSI are used by the port B so im not use my version ISP (in circuit programmer) would run on the same circuit or i would need swicthing. anyway the curcuit has been planned to use LPT for programming while rs232 for interfacing so both activities can theoritically happen wihout me changing plus. LPT is anyway missing from new boards. mine is p2gz845 which does have it.
