F9R hookup guide
You might think that ZED-F9R is a ZED-F9P + IMU and sensor fusion. It is not. Currently ZED-F9R accuracy with RTK corrections is 20cm.
u-blox says it says that current version of F9R only supports asphalt road vehicles in street driving conditions (a.k.a. cars and trucks and not offroad).
I don’t think need the dead reckoning features.
i seen some information that led me to believe the SparkFun surveyor unit would be able to be used for a steering system and also as a base station unit for more accuracy
do you know if this is correct?
it is more expensive , i will certainly look into the one you mentioned
thank you
Aren’t they both based on the same u-blox module? The Ardusimple product can equally be used as a base or a rover and the accuracy is equal.
Thanks for previous information
Ardusimple is interesting
Now to figure out which is best
Do you know of someone that uses cellular network to interface?
Was hoping to make it work using phone data plan instead of other radio modems
Might make simpler at first
Got hills and trees in way so line of sight maybe not achievable
Do you have opinion on this?
On my AgOpenGPS setup I use my cell phone for RTK correction data over NTRIP. On our commercial receivers I also use NTRIP with a dedicated SIM card. I pay 10 Euros per year for each. I would say cost is not an issue in either case.
Difficult for me to understand but some countries have poor cellular coverage and NTRIP may not be the best solution. I come from a very sparsely populated country and I cannot find a field with poor cellular coverage. Then again, some farmers from small and densely populated countries complain a lot. We have to understand that there is no single solution for everyone.
It’s probably easiest for now
Thanks
Have a good New Years
Somehow I have problem signing into GitHub
I am trying to hookup the cutting
MD 13S
The citron
Says control pinout as follows
Dir
PWM
NC
GND
The Arduino drawing diyAutoSteer
Shows
Arduino
Pin D4 wire 11.7 to pin1 Dir
Pin D3 wire 11.6 to pin2 PWM1
Pin D9 wire 11.12 to pin3 PWM2
Otherwise ground to pin4
Have I got wrong drawing or wrong cytron
The cytron has a pin NC
I assume it means “no connection
What am I missing here
Thank you and happy New Years
Looks OK to me but I’d check the above to match your ino code. What ever drawings tell, Arduino works as defined by the code. This is from 4.3.10:
// *********** Motor drive connections **************888
//Connect ground only for cytron, Connect Ground and +5v for IBT2
//Dir1 for Cytron Dir, Both L and R enable for IBT2
#define DIR1_RL_ENABLE 4 //PD4
//PWM1 for Cytron PWM, Left PWM for IBT2
#define PWM1_LPWM 3 //PD3
//Not Connected for Cytron, Right PWM for IBT2
#define PWM2_RPWM 9 //D9
How you doing today?
I got start on making my board
On the drawing it shows .
4 connections to the analogue to digital converter
5V
Ground
Sense high
Sense low
Do you know what sense high and low refer to ?
Some things only have one output wire
This seems to have two
Sense high and low are used for a differential signal. If your WAS has only one output, you would find the correct input (out of the two) from the documents included in the support files. If I remember right, you would use the sense high input. The signal should be the voltage between WAS ground and the WAS signal output.
Thanks
That helps a lot and makes sense now
What type of sensor do you use?
What do you think about the
1993-1013-ND
Amphenol Piher from Digi-Key
Hall effect type
I believe I got the information from someone on Agopen
Seems like it should be good
Specs look good to me, your choice of the price range and which one is mechanically simplest to install. You’ve probably looked at other threads talking about many other WAS products:
Interesting sensor.
Remember to consider if you want the 90 degree or 180 degree version of the Piher. Most front wheels does not turn more than + - 40 degree, so to get maximum use of signal range (about 0,5v to 4,5V) a 90 degree version would fit best.(Digi-Key number 1993-1014-ND)

Do you know what Arduino pins
D2 and D5 are for?
Both are connected to J2
Nothing unless you modify the code for your own use.
couldn’t find anything either
Might of been for something in the past
Thanks for your time

Hi I have a trimble DA2 and cant get it to work. it connects ok but seems to be giving gobbledegook messages out. Any ideas?
Serial baud rate set the same at both ends?
