LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Cant do this anymore bye all wrote:

It's a one to one connection. Pin 1 to Pin 1 etc. The wire with the red tracer is pin 1.

I have a 26 Way IDC Line Socket from jaycar here in Sydney image is below but it has no pin numbers marked.  Searched like mad but no luck.  Your help will be much appreciated. The D25 IDC has numberings marked!

Plug it into the male header on the board.
Where it aligns with Pin 1 on the board, that will be Pin 1.

Dear meister：

When I tested RIO, I was a little confused。

1. I set spi clk is 10Mhz, but 6.4Mhz actually
 
 
2. and I set shiftreg clk 1Mhz, but 323Khz actually
 
 

FPGA is ice40up5k

Is that correct?Thank you.

Tim

Hi Tim,
your measurements are correct,
the code is wrong

I have fixed the shiftreg plugin,
but the 6.4Mhz of the w5500 are correct,
more is not possible with the ice40up5k on 30Mhz clock.

Thanks !

HI meister:

Thanks for your reply.

I will test that later.thank you very muchimage missing /media/kunena/emoticons/laughing.png

and I have a promblem about w5500 spi clk:
I tested the joint.n.f-error seem biger than mesa card,
my PID is: P=1000 I=0 D=0,when i jog x axis,the joint.0.f-error is about 0.05mm
if i set P=0,I=0,D=0,when i jog x axis Exceed about 800mm,the "joint 0 following error" pop up（I set FERROR=3）
The difference between the feedback value and the command value is getting bigger and bigger
I know when i used a low speed run the axis,the f-error is good for me, I'm just a little curious, it's related to the spi clock?image missing /media/kunena/emoticons/tongue.png

Thanks
