@chrishamm I have tried to run the command gpioget gpiochip4 28 and tried also with gpiochip0
and it gave me this error: gpioget: error reading GPIO values: No such file or directory

any suggestion?

@chrishamm thank you for your reply. Yes I realized installing DSF is the easiest way.
However I have few questions regarding the connection between the SBC and duet:
are they 5 wire connection in total? is the connection below right?

Also how to identify the GpioChipDevice and TransferReadyPin? I couldn't get any info from gpioinfo and gpioget

Is It possible to send gcode command from a tinker board to a Duet board via SPI without installing the DSF on the Debian OS?

this is the code I am using with Python-periphery library but nothing is happening.

from periphery import SPI
spi = SPI("/dev/spidev1.0", 0, 1000000)
data_out = b'G1 Y180 F5000\n'
data_in = spi.transfer(data_out)
spi.close()

@Falcounet I am calling macros to rotate motors and control sensors.
the code is something like this:

def send_command_duet(command):
with serial.Serial('/dev/ttyACM0') as ser:
ser.setRTS(True)
ser.write(b'\n')
ser.write(command)
eof = False
while not eof:
line = ser.readline()
if line == b'ok\n':
eof = True
print(line)

while True:
Capture image
classify image
send_command_duet(command) #perform action
receive signal from duet to go to next iteration

@Falcounet I am performing some image classification in a loop on the RPi and based on that the duet will perform some actions. But sometimes the mechanism controlled by the duet gets jammed and the python code keeps running. So for each time the Rpi sends a command I would like the duet to be able to send back a signal/command in order for RPi to perform the next image classification.

@Falcounet Is it possible to communicate back from the Duet to the Raspberry Pi such as if a condition is met stop the python code?
I would really appreciate your help again

@jay_s_uk I believe this is a different question

Hi guys,

I am new to the duet, I have connected a duet3D Mini 5+ to a raspberry pi 4 through usb cable. I am trying to send a command to the duet in python to run a gcode file (macro) on duet3d 5mini+. Any suggestion on how to do that? thanks

@Falcounet I was able to get the motor to rotate with your code:

import serial
with serial.Serial('/dev/ttyACM0') as ser:
ser.setRTS(True)
ser.write(b'\n')
ser.write(bG0 Y30 F50000\n')
eof = False
while not eof:
line = ser.readline()
if line == b'ok\n':
eof = True
print(line)

thank you very much!!!!!!!!

@Falcounet it gives me a wrong wi fi address ----> b'WiFi IP address 255.255.255.255\n' thou..

Also, right now if I run :

import serial
ser = serial.Serial("/dev/ttyACM0", 115200)
time.sleep(1)
print('read')
ser.write(b"G0 Y30 F50000\n")
print('write')
time.sleep(2)
ser.close()

the code it doesn't get stuck anymore but still cannot get the motor to rotate

also what does this line mean?

@alankilian thank you for your reply. I have tried that but still didn't work

I have connected a duet3D Mini 5+ to a raspberry pi 4 with a usb cable. I am trying to send gcode commands to the duet through the serial package in python. I have a stepper motor connected to the duet. So i am trying to send a command to rotate it. when i run the python script it just stops at line (ser.write) and it doesn't execute the subsequent lines.

here is the code:

import serial
ser = serial.Serial("/dev/ttyACM0", 115200)
time.sleep(2)
print('read')
ser.write(b"G1 Y10 F5000\n")
print('write')
time.sleep(1)
ser.close()

if I connect the duet to the laptop and execute the gcode line in the YAT terminal it works fine.

Am I missing something?

@Falcounet yes. if I set a value for write_timeout in serial.Serial() then it exits the code with an error after the amount of time that I set, but still cannot tell the duet to rotate the motor

@Falcounet I have tried that and still no luck..

@Sindarius thank you for your reply. I have tried that and no luck..

if I connect the duet to the laptop and execute the gcode line in the YAT terminal it works fine.

I don't really know what I am missing

@jay_s_uk thank you for the response, I would prefer use only the usb port for communication
