That depends on type of transducer! Is it off-on or 0 to 5v output or 0 to 10v output or 4 to 30 mA output.
Lets say it is off-on then you could set encoder count to 1 in the ino and connect to Imp on pcbv2 (activated from Nano pin D7) and autosteer will turn off after one spike in pressure.
If 0 to 10V I believe you could also use the Imp, and maybe even insert a potentiometer to adjust the setpoint of pressure (When led inside OK1 lighs enough to switch the port)
0 to 5v could be direct on a nano pin.
BUT till now I donĀ“t see this function is available in pcbv2 ino. So you must use one of the Coffeetrac inoĀ“s (autosteer_button.ino or autosteer_switch.ino) they have the function to use an encoder, and you decide yourself if encoder must trigger 1 or 5 or ?? times to turn off autosteer. You must use pinmapping 1 and use 1 time to trigger
As far as i understand new pcb ino will still work on pcbv2, and if not then I believe both inoĀ“s will be available in support files.
I am also confused about the remote as it is also called auto in latest schematic.
From what I can see in my tractor schematics it looks like the pressure transducer is given 5v and will be variable. Until the plug for the sensor comes in the mail I cant test to make sure. Makes me wonder if it should be read on an analog pin. That way whenever it hits 5v it could be triggered, or I have it run into a secondary arduino first and that arduino feeds the imp switch on the main arduino.
I also have a lock out solenoid on my valve block that I need to hook up. I may need a relay hooked to the pcb v2 that triggers when in autosteer mode.
Do you think the 5v with variable would work because I assume the output voltage would ride as the pressure increases. We need it to be more of a switch. I ha e similar setup just need to get mine hooked up to see what my pressure switch does
Would a variable sensor be useful for setting the threshold at which deactivation happens. To prevent accidental deactivation by knocking the wheel. I know the Topcon steering wheel has a torque level setting that can be varied.
Looks good to me, it also looks like a much better soldering job than my first attempt. Fire it up and see if any magic smoke comes out As long as the pinouts donāt change on the new .ino you should be fine otherwise itās just a matter of changing the .ino pins to match this PCB. Hopefully it works well for you.
In this setup the hydraulic pressure contact is a on off type.
To replicate that situation with your transducer I would build something with the transducer connected to a potentiometer(and maybe a resistor or two) and let that combi activate a relay with a optical 5V input (arduino module type) If you have a double module, one of them could be for this auto off function, and the other for the shut off valve.
With the potentiometer you could adjust how high pressure must be before activating relay.
" In this setup the hydraulic pressure contact is a on off type."
āpressure contactā are mechanical switch activate when relief valve open , max left or right position or malfunction.
Set one pin on arduino nano ERROR, and connect with āpressure contactā , and in PID.ino you process information. Stop āwind upā PID ,and āreturnā 1-2% PWM.
i have folder with just one folder in it āArduino Codeā in this folder are 4 folders
Autosteer_UDP
Autosteer_USB
Machine_UDP
Machine_USB
None of them have a āgerberā .gbr File in them
?
Iām using pcb V2 and have the arduino connected via USB. I think some use ethernet because they can upload ino files while connected to AOG at the same time, but Iām not sure.
Iām lookin at starting to look at ordering parts for this project and Iāve seen that there is work on a new PCB version. Should I stick with this one for now or?
