5i25 + 7i85s +....

Thank you!

I think i have wired it correctly. Now i´m messing with the HAL file.

The thing is that i dont have a specific PIN for the TX6 and TX7, these are the phisical outputs of my 7i85s that i want to use for the ENABLE and PWM purpose of the SPIN1X.

How are they labeled in the HAL configuration?? There appear position-cmd and velocity-cmd for example, but i guess they aren´t the PINS i have to use.

Any advice??

Thank you again!

EDIT= In the manual of the 7i85s i´ve seen the GPIO´s of the card. It works nice. Thank you!!

For running the SPINX1 you need a FPGA configuration with a PWM generator
what FPGA configuration are you using?

You can read out the FPGA pinout with:

sudo mesaflash --device 5i25 --readhmid

Hi,

My FPGA system is 5i25+7i85s. I have connected to it 3 encoders and 3 motors. So i have DIF OUT 6,7 free.

I have run the command :

sudo mesaflash --device 5i25 --readhmid

and it returns

sudo : mesaflash : command not found

The LED´s of the ENABLE and DIR are lighting in the SPIN1X. I have wired the ENABLE PIN of the SPIN1X to the PIN TX7 of the 7i85s. In the manual says that this TX7 PIN is the IO19, but i switch on off this pin and the LED doesnt switch off, so i guess that this PIN is always 0.

What am i doing wrong??

Thank you!

Ok, i have installed the mesaflash and this is what i take from the command:

As i understand im trying to use the IO19 for P2 and IO2 for P3, which is the HAL name for these PINS?? Which do i have to use??

Thank you!!

EDIT--> In the HAL file do i have to put num_stepgens=4 to activate these PINS? or do i let as it is num_stepgens=3??

You probably want to use 5i25_7i85sspx2.bit since it has PWM gens on TX6 and 7 (on both P3 and P2)

The question was concerning to one PIN, with mesaflash it shows this PIN as IO19 and IO2. In the manual of the 7i85s it says:

FPGA PRIM I/0 -->IO2

FPGA SEC I/0 -->IO19

For the function TX7. In my system the SPIN1X is wired to the 7i85s so i guess the GPIO IO19 is the HAL PIN i have to use. But maybe im guessing too much.

The question of the num_stepgens=4 or 3, is because i have 3 motors in my system so i have always had num_stepgens=3, but i dont know if have to change to 4 in order to activate this PIN, but as my purpose is to use this PIN as GPIO i dont know if i have to add another stepgen to my HAL file.

Thank you!!

What daughterboards are connected to P3 (GPIO 0..16) and P2 (GPIO 17..33) ?

Where do you want the SPINX1 to connect (P2 or P3)

In any case, the firmware you have will not work with the SPINX1 because the SPINX1 requires a PWM generator
so you must use 5i25_7i85sspx2.bit or something like it that has both stepgens and PWMgens

I have a 5i25 connected via PCI slot to my PC and a 7i85s connected to the 5i25 via paralel port cable. My SPIN1X is connected to the 7i85s via the DIF OUT 7 to the ENABLE. I dont know what P3 and P2 means, sorry.

I guess i need to use the the hm2_5i25.0.gpio.019.out, but im not sure. Do i have to activate another stepgen in the HAL file to make it usable??

I have downloaded the 5i25_7i85sspx2.bit file. How can i install it?

Thank you!
