Arctic Hare mod by Jussi

No RTC found.. I also tried i2c test. That just put buzzer constant on and no serial output. Maybe i2c bus is faulty

Edit: It wont found IMU-module also, no i2c devices found when scanning i2c devices.

So, i2c bus wont work, something with p20 button and battery voltage measurement little off

Charging wont work. battery voltage is 24.8 and charger 29,5. Station led lit but no laderelais

Code:

First you need to disconnect the IMU module and the jumper.
The RTC need to be alone on the I2c bus when use the test
Upload the code below and check if RTC is found .If yes you can add the IMU and test again.
RTC have 2 adresss and Imu 3 if i remember.

No devices found. IMU wasnt connected earlier, I just tested it to see some i2c device found/working

Very strange the Power issue (Are you sure all the capacitor in correct polarity)

Charging wont work. battery voltage is 24.8 and charger 29,5. Station led lit but no laderelais

This can be normal if in Pfod the charge start if below if not set according to the battery voltage

Voltage on battery is 24,95 on multimeter, not that 21.65.

This is not OK ,did you mesure the 24.95 with the PCB1.3 connected and powered ?

Is the +5VP present on the RTC ?

jussip · 17 März 2019

There is 5v, all other voltages are ok too. 3.3v, 3.3vp etc.
I'll check capasitors. Is that relay for change to charging mode? How I get it to change state

bernard · 17 März 2019

The Charging relay can be ON only if the mesured voltage of battery is lower than the value you put in setting battery (charging starts if Voltage is below)
Try with 20V.
Battery monitor need to be YES.
In Info menu try to set developper to yes and return into setting battery to adjust the calibrate batfactor to read the correct Voltage battery.

jussip · 17 März 2019

Code:

batMonitor                 = 1;          // monitor battery and charge voltage?
batSwitchOffIfBelow        = 20;       // switch off battery if below voltage (Volt)
batGoHomeIfBelow           = 23.7;       // drive home voltage (Volt)  	
startChargingIfBelow       = 32.0;      // start charging if battery Voltage is below (99999=disabled)
batFull                    = 29.4;      // battery reference Voltage (fully charged) PLEASE ADJUST IF USING A DIFFERENT BATTERY VOLTAGE! FOR a 12V SYSTEM TO 14.4V		
batFullCurrent             = 0.1;       // current flowing when battery is fully charged	(amp), (-99999=disabled)

So, it should be charge with these settings? (relay wont change state and no charging)

bernard · 17 März 2019

Sorry i edit the post.
If the battery voltage is read correctly ( from 24 low and 29 Full)
batSwitchOffIfBelow need to put 23.8 The PCB1.3 shutdown if the bat is lower and JP8 in autom
startChargingIfBelow need to put 26

In your case if the bat reading is 21.65
batSwitchOffIfBelow need to put 20
startChargingIfBelow need to put 27

And normaly the Relay is ON

Have you adjust the bat factor ?
Can you show all the console start message ?
Is the EEPROM working ?

I did adjust batfactor but seems that its not saved.. Eeprom test end "rtc missing error"
My relay wont change its state, no matter what I do

bernard · 18 März 2019

Into setting ,try Load factory setting and save setting
Into the console normaly the due freeze for 5 or 10 secondes during the saving if the eeprom is ok.
If it is very fast the eeprom don t work .
Certainly Need to test with a new RTC (many of them have trouble).

jussip · 18 März 2019

Its fast, no freezing

Code:

system will reboot now...

bernard · 18 März 2019

Maybe if you have a 5v arduino like mega or uno you can test the rtc alone on breadboard .

jussip · 18 März 2019

I'll test it today with nano but there might be some other problem also..
P20 push button, is it NO or NC?

bernard · 18 März 2019

It is NO but like in video 7 you can simply shunt the 2 wire.
The ADC calibration is usefull for a correct voltage battery mesurement.
If the eeprom don t work normaly the pcb start with all the (mower.h or .cpp) value ,so disable all odometry,imu,perimeter,gps etc... inside this file for first testing

jussip · 18 März 2019

RTC is ok, its working fine with nano. I think that due is faulty one.

jussip · 18 März 2019

Very small D13 diode was placed wrong direction, turned it and now button works. EEPROM and RTC errors still present.
I tried pcbtester.ino script to test charging, it works when manually turn D51=1. Charging wont start automatic, those errors may prevent it?

bernard · 19 März 2019

Good for D13 but it's factory solder no ??
For the charging i think it's better to first solve the RTC issue or i2c bus.

jussip · 19 März 2019

Under DC/DC buck. SMD factory soldered, small one behind resistor. I went pcb through third time, checking solders, polarity etc. No idea whats wrong. RTC does not show on schematics, maybe its 5/3.3 converter? What voltage sda and scl pins should be on due?

bernard · 19 März 2019

RTC does not show on schematics,

Here what do you mean ?
Into Kicad the RTC is into the I2C page.
DS1307 Is the RTC and include also the eeprom.
It is connected at the input of the first PCA9517D and use 5VP on VCCA so you can't use the I2C line if something wrong here..
Be carrefull here SDA1 and SCL1 are not the DUE one.

All the 7 PCA9517D output are connected to DUE SDA and SCL so if one is not OK all the line is KO.

Voltage on Due is 3.3V max on SCL and SDA Also.

The RTC module is low price so maybe good practice is to order orher one to be sure (many member have trouble with this kind of module i have 3 of them totaly new that never work).

jussip · 19 März 2019

Right upper corner i2c page, texts are one on top of the other on my printed schematics.. anyway, voltage on due SDA and SCL line is 1.7-1.8v and about same voltage is also on due SDA22 and SCL22 line (I2C1). other side of PCA9517D's are fine 5v/3.3v
Ordered yesterday few more RTC's already but seems that fault is elsewhere
