Hi,
I’m using CW308 + CW-Lite and want to test the voltage setting is correct or not.
Take CW308 UFO - NewAE Hardware Product Documentation for reference,
I connect the VCC1.2 to FILT, connect FILT to VREF. About the jumper, J4 use the mode which means VREF Network set by VREF Pin from Victim Board (DEFAULT), J14 use the mode which means Filter input set by FILT Pin from Victim Board (DEFAULT).
I do the small test using print(scope.io.tio_states)
, the code is as the following:
scope.io.tio3 = "high_z" # async_InReq_o
scope.io.tio4 = "high_z" # test_done
Connect J5/GPIO4 to J11/FILT_HP and J5/GPIO3 to J11/FILT_LP, then
while(1):
time.sleep(0.005)
print(scope.io.tio_states)
The result should be (0,0,1,1)
, but why does it always print different results such as (0,0,0,1)
, (0,0,1,1)
, (0,0,0,0)
, or (0,0,1,0)
? What could be the reason?
I have try change the jumper wire, or connect J5/GPIO3 or J5/GPIO4 to VCC1.2 directly. It still has the same issue. Did I misunderstand the document and do the wrong setting?
Thanks!
