Hi, i've been using DS39563B for my PICdem.net design. It's just the same like in your's. The 470 Ohm resistor (r10) is in series too. I've tested the design and it works fine!dpechman said:im drawing in pcad the board of PICDEM.net with reference of DS39563A.pdf (microchip AN) and saw an problably mistake:
in page 69, S3, the key that is connected in PortB.5 of 16F877 are in series with the resistor(R10) once the tipical configuration for this resistor is like pull-up or down...
someone that have a new one schematic or the original board can confirm it to me??
I've done this Job. I built up the Microweb project from Kim Olesen, and i saw that there are too many bugs. So i changed the board to picdem.net by using some Verowires (only a few changes). I've posted the Microweb Eagle files, so you can change it to picdem.net yourself (look for the schematic of DS39563B). My project uses Realtek 8019 ISA card.picman2 said:"System.out", are you still busy in drawing a PCB for PICDEM.NET board look-alike?
I'm wondering if someone managed to build a clone (o a near similar system) by using a standard NE 2000 card based on picdem.net schematic.
All the schematics I saw on the net using NE2000 + PIC are not compatible
with the standard board, so software modifications are needed to run the original software on it
I'm about to start this project, and I wouldn't reinvent wheel or warm water ...
If you're still interested please find bellow v2.61Sobakava said:anyone have p18web 2.62 or previous version?
If someone has the schematic, it would be nice to see it...
