Project logs / Re: Cheap DIY Usb Blaster compatible programmer
Thanks for the comment.  I think you are right.  I am still hoping to hear from someone that has actively used this with Altera Cyclones.  I really don't want to update the code, although I could if I had time.

Quote from: bennyboy
Hello, I just built a USB blaster clone with a 18f14k50 (v0.7 revision on creator's page) and used it to program a Cyclone II device. Worked really great!! I did not install the 5 * 200ohms resistors. The IO ports on the PIC18f14k50 are already +3.3V and the device I was programming needed 3.3V.

Hey bennyboy,

Are you referring to the design that started this topic?  Any further experience with it?  I want a circuit to put onto the board along with the Cyclone 4 FPGA so that it has the USB interface for programming built on.  Does this design seem reasonable for that?  The schematic does not give the crystal frequency but the parts list says 24 MHz.  Is that correct?

Thanks
