Looks good! I know one can go to town on what to put on the board, but a second LED on one of the port lines(on pcb) is invaluable. It allows easy checking on power up/diagnostic//// without having to actually make connections to the board. Also, I see some port lines don't come out, like TX does but not RX or RB0. Maybe RA5 could be that diag. LED Also; - I see there is no provision for the little capacitors across the Xtal. - The pads that are directly into the copper ground plane will be quite difficult to solder unless broken into islands. - Since one is unlikely to use a top-silk, some text on the copper can be really helpful too. Also for the PCB house to identify your board (remember to flip text!) Some text worth considering; - pcb name - date or serial No. - + - - 1..6 Regards Roland At 11:58 PM 11/05/2005 -0700, you wrote: >On May 11, 2005, at 10:47 PM, Alison Lewis wrote: > >> Please follow Mr. Westfield's communication. > >I made some more changes. fiddling with others PCB designs is good >practice!
