Has anyone compiled the code and hooked up a ESP32 & Ethernet Module ?
Have I both now sitting in the "lets make something box" but I'm having an issue with the ESP32 to Ethernet Module hookup. The SPI signals seems easy enough to find info on, but the RESET & CS seem a bit iffy. I've spent a few hours looking and seem to come up with different pins.
Yeah yeah I know I'm probably missing so simple.

Velocity feedback only.

I've had the Trinamic TMC2209's running in velocity mode over UART. Really neat but lacks the internal feedback of the software step generator.
No serial feedback from the drivers then?

Thx, I saw same and its' cleaner, about a dozen gpio left over
and a simpler package.
bit.ly/34eTCfX
or
www.wireless-tag.com/wp-content/uploads/...6%96%87%EF%BC%89.pdf
There are a LOT of 'esp32' boards
I have DOIT ESP32 DEVKIT V1
and i've found 2 versions
so
finding the correct pins can be hell
and NOT having to find them is nice.
( a bonus of a pcb containing 2 major components)

Hi Scotta
I have problem compiling the src code from
github.com/Deotti-cl/linuxcnc-esp32
github.com/Deotti-cl/linuxcnc-esp32
Is that the correct repo?
I have a breand new ,empty, clean, install of Arduino IDE,
arduino IDE 1.8.15
and I have configured for ESP32 devices using Board Manager
and chose my DOIT ESP32 DEVKIT V1 from the list
I can compile and run wifiscan without problems.
but the linuxcncinterface.ino
gets me this message
What am i missing?
Thanks TomP

Try this
From here:
github.com/dlhenke/linuxcnc-esp32/blob/m...inuxcncinterface.ino
udp.comp needs some extras, the scale as parameters, the ability to set the IP Address when loading, and updating some of the socket functions (working on that ATM). Tho it does work as expected, the above just make it nicer.
The CS/SS pin needs to be set correct for your particular board.
There still needs to be some work done on the GPIO pin numbering for the DIR pins
#include <stdlib.h>
#include <driver/gpio.h>
#include <Arduino.h>
#include <Ethernet.h>
#include <EthernetUdp.h>
///#include <mcpwm.h>
///#include <ledc.h>
#include <esp_timer.h>
#include <driver/rmt.h>
#include <string.h>
#include <ESP32Encoder.h>

i made some progress
i edited linuxcncinterface,ibo
changetoand xhangeto
and
install ESP32Encoder using library mgr
now it will compile
but i have not tested it
There used to be a processing driver pde
but it is not in the tail of linuxcncinterface.ino
i saw it somewhere in my travels

@ BeagleBrainz
Thanks i discovered similar
both compile ok
rom/gpio.h
driver/gpio.h
and your suggestion lookks better

@scotta @BeagleBrainz
Hello, please addto your list
All original #includes can be removed
IF yours plus this esp_ipc.h are in the file
( no need for FreeRtos etc )
It compiles and loads fine
and the pins can be seen in halbut theres are pins listed that dont exist on my 30 pin devkit1 board
I will go now to study the comp src to see what params may exist
and how a .hal file would be made to use this
There must exist a config(hal and ini ) if we watched the video.
Are they published?
Should the RST pin be set High? (d26 on esp32 , RST on w5500 )
Also I am still looking for the .pde that tests the .ino
I have it someplace but have misslaid it.
Thx TomP
