Sounds okay. - i'd prefere a sil iscp and won't use the rj* one - please add power supply (+5v) to the serial/i2c connector, so the board can be connected using this one connector.
Joep PS board_16f88_sil.jal descricbes the pins I used (just saw I missed the rs/e pin numbers). 2009/3/9 Richard <[email protected]>: > > Thanks for your schematic, i will make a nice drawing and add some > furthers like > serial/i2c combined connector selected with jumper. > 3 kinds of lcd connectors (2 hd44780, 2x5 and 1x16, and 1 dogm) if > possible (try to make a single side pcb and a minimum of via’s) . > mosfet controlled backlight. > 1x5 sil for iscp or do you want a RJ11 6/6 connector like ICD2 from > microchip or both or a complete different one?. > If possible I will use some good to be handled smd components. > And of course own 5Volt stabilized power. > > if somebody have more ideas please let me know. > > Richard > > On Mar 9, 9:53 pm, Joep Suijs <[email protected]> wrote: >> Hi, >> >> Enclosed a draft schematics of the circuit I build. >> >> Notes: >> - the 8 pin connector on the left is my icp connector.
