Hello,
I try since a couple of days to get cs, read and write signal on outputs of my de0 nano board.
The goal is to drive a motor controller (LM628) which needs ck 8Mhz, cd, rd ,wr and a 8 bits data bus
For the ck it's ok. I use a altpll function under Quartus.
For the other signal I have created under Qsys:
Clock source (50Mhz)
Nios2/e processor
Generic Tristate controller
Tristate Conduit Bridge
I take care of the links between each block.
They have all the same clock. No error message during generation.
Under Eclipse I write a small loop which make a write then a read on GENERIC_TRISTATE_CONTROLLER_0_BASE
Then I run the program ... but nothing on outputs! cs stay at 3V3.
Someone has an idea on this problem?
I see a note (2011) that we have to put a Tristate conduit Pin sharer on some kind of Cyclone. I tried but no change.
Thank you per advance for your help
Serge
