Breakout boards / Re: DP6037_SMT.v1 free pcb build
I did not understand how the zig zag area should be used, It could definetly use an icsp header
maybe somme ground and supply rail.

overall this worked.
I would like to try the xQFP80 +65 Protoboard but still one coupon code short.

This board was really fun to build, I wanted to get a PIC18F2550 breakout board, but now I made it on this nice pcb.
really like this prototyping posibility.

Breakout boards / ATX Breakout Board v1.0 free pcb build

I built this pcb, it seems that my supply does not have -5v
I used wire from stranded wire instead of fuses, and a bridge for the switch, the psu has a mains switch.

Breakout boards / Re: FT2232 output frequncy generator
I can`t see where to disable port b

A software command (Set Bit Mode option) is then sent by the application to the FTDI driver to tell the chip to enter single channel synchronous FIFO mode.

how can I send the Set Bit Mode to the Ftdi chip?

Breakout boards / FT2232 output frequncy generator
I have ft2232 breakout board and xc2c64a cpld breakout,
I don`t have a 7x5mm SMD oscillator for the cpld breakout.
I would need to generate a pulse from ft2232 as timer for the cpld

is this possible?

and connected to a ft2232 breakout board for programing.

should work like a Bus Blaster :)

ps.
why was this pcb called v1a draft ? is it missing something?

It looks like urjtag doesn`t like W7 64bit os
I tried again on xp and it looks ok.

CPLD programmable logic / XC2C64A dev-board v1a draft build
I have built this board, all look ok.
I have a ft2232 breakout board and connected it to the xc64 jtag like in the BB (BDBus0-3)
downloaded the BusBlaster.package.v2.0.zip  and extracted the ujtag folder

this is what I get
