RPI 4 + Mesa 7c80 VFD Spindle Config was created by BenStPierre

Hello,

I've been reading many posts on the forum for a while now and there's a lot of information out there, but not much for the Mesa 7c80.
I'm currently running the master branch and have followed this post for the most part: forum.linuxcnc.org/27-driver-boards/40315-7c80-install-on-rpi-4

I'm trying to use the mesa analog spindle output to control my VFD and so far I'm stuck at the spindle enable pins. I have found that on the 7c80 spindle enable is gpio 20 and spindle direction is gpio 21, but I'm missing something somewhere because I can't get any spindle control output from the board itself.

I have found the issue to be the same as on this post: 162.243.45.186/39-pncconf/37417-spindle-...QNo6Gd3tGeITry6bKChE
but on the mesa 7c80. Can anybody point me out in the correct direction?

This is the error: ./metal_3D_printer.hal:363: Pin 'hm2_7c80.0.spinena' does not exist

What are the spindle pins for the 7c80?
I suspect that the firmware on the mesa needs to be flashed (now it's as received from Mesa) to enable the spindle output or something. running readhmid gives this: (I'll also attach the .hal and .ini)

Spindle analog output on a 7C80 is controlled by the PWMgen (PWMgen 0)

Thank PCW for answering!

I think I'm confused, is the analog output and the 0-10v+ virtual potentiometer the same thing?

my VFD is wired to the SP-, SP and SP+ pins on the 7c80.

So what should I follow on this page (linuxcnc.org/docs/html/examples/spindle.html) the VFD or PWM HAL setup?

Thanks again
Ben

No, you would setup the Mesa hardware PWM.
To list the available pins/parameters you can type these commands
while linuxCNC is running:

halcmd show pin hm2_7c80.0.pwm
halcmd show param hm2_7c80.0.pwm

Replied by BenStPierre on topic RPI 4 + Mesa 7c80 VFD Spindle Config

Hey thanks for the reply, but when I do this with LinuxCNC running there are no PWM pins or parameters. Does this mean I have to flash the mesa to configure it?

Thanks in advance,

Ben

The firmware contains 1 PWMgen for the spindle:

Module: PWM
  There are 1 of PWM in configuration
  Version: 0
  Registers: 5
  BaseAddress: 4100
  ClockFrequency: 200.000 MHz
  Register Stride: 256 bytes
  Instance Stride: 4 bytes

It likely you have the PWM generator disabled in your hal or ini ifile

I do this with LinuxCNC running there are no PWM pins or parameters. Does this mean I have to flash the mesa to configure it?

You have
loadrt hm2_rpspi config=" num_encoders=0 num_pwmgens=0 num_stepgens=5"

try

loadrt hm2_rpspi config=" num_encoders=0 num_pwmgens=1 num_stepgens=5"
