[hpsdr] Trying to get Blinkity to work on a v2 Ozy

[Bill Tracey]

Hi Charles,

Nice to see someone hacking the FPGA code.

Are you starting form a blank project?  I usually start from an 
existing working project  and then cut it down to what I want -- this 
usually gets me the correct pin definitions, device setups etc.  The 
Quartus project we use for Ozy/Janus can be found at: 
svn://206.216.146.154/svn/repos_sdr_hpsdr/trunk/OzyV2-JanusV2

As to where to look for Pin assignments,  in Quartus under Assignment 
-> Pin Planner, or Assignments -> Assignment Editor will show the Pin 
Assignments.    You may also need to tweak the device settings 
under   Assignments -> Settings -> Device -> Device and Pin Options ...

Under General I usually check
         Auto-resart config after error
         Enable INIT_DONE output

Under Unused Pins  - As input tri-stated

Under Dual Purpose Pins
         ASD0, nCSO -  as input tri stated
         nCEO - Use as regular IO

Under Voltage - Default I/O Standard - 3.3v LVTTL

The DEBUG LEDs attached to the FPGA are DEBUG_LED[0-4] and they're 
assigned to Pin 4, 33, 34, and 108 respectively.  Pin 108 is also 
nCEO, so Quartus probably does not allow you to assign that unless 
you've got nCEO set as a regular I/O in the Dual Purpose Pin 
settings    The remaining LEDs are connected to the FX2 and to the 
INIT_DONE line on the FPGA, so they're not user programmable from the FPGA.

Hope this get's you going .. if not come on back with some more 
details/questions and we'll try again.

Cheers,

BIll (kd5tfd)
