Do you tested old round displays?

I do think so, but I am not 100% sure. I do not have a CU2 setup ready for testing, but maybe VoidSpark can recall if he tested the round CU2 displays also.

 

[void-spark]

I might have used a round display a long time ago, but it certainly hasn't been tested in forever So far it seemed to work pretty much the same as the square ones, but I guess there might be some difference

Damn, nice display's collection In Poland peoples charge lot of monney per one piece

PCB recieved

 

[szupek]

This was quite fast! Have you managed to test it already? Willing to sell one or two?

 

[dvjcodec]

Not yet, but I hope Sunday solder components. Yes, I can send to U two pieces. Catch me on FB -> Krzysztof Dymianiuk

 

[void-spark]

Works fine on original battery.
on orig batt bow bus 24v
on esp32 bow same 24v
Vcc 5V on orig and 5v on esp32
Used latest firmware version.

Well, on my desk test setup (with fake motor), it currently runs fine with the one round display I have left that still works..
There are differences, it's esp32c3, fake motor, and currently resistors and voltage are for 32-42 volt range. But none of that should really have much effect.
If it really is software causing this, you can try sending a log (ideally, a log of it working with the original battery, and a log of it failing with the esp32).

Installed openlog as a 'permanent' addition to the breadboard on my bicycle too, so I should be able to capture a log of it stopping to respond after sleeping. HAve a log of today, but the issue didn't occur ofcourse Did have the display not giving anything for a bit after one time parking and removing the display though, so there might be some interesting bits in there Mind, these logs are huge (well, relatively, 4mb for today, but that's a lot to dig through. I need to add something to look for or at least graph trip/total time/km and so .

Finaly done,
now I have to learn more how to run it

Looks so nice!
Let me know if there's questions about the software

My test-stuff
I try to compile firmware under visual studio, but now have error missing button.h

fatal error: button.h: No such file or directory
18 | #include "button.h"
| ^~~~~~~~~~
compilation terminated.
ninja: build stopped: subcommand failed.

Latest, precompiled firmware downloaded from this topic (may 2022), uploaded to ESP32 via web, follow instruction, tested under web esptool-js.

Motor board connected to ESP32, so display connected too. Display ON, I can go to menu, try to start calibration (from menu or pressing BOOT on ESP), but nothing happened Trip on display is still 0.00, and after few seconds display flash Batavus splash screen and no londer menu available.

What I doing wrong?

The board looks great! well done

The toprun motor (probably) only supports 9600 baud, CU3 display can do 9600 and 19200. Do you use 19200 or 9600 baud?

CU3 will start up with power and bow connected, but without communication or when you stop pushing the buttons, it will go in standby very quick.

Build locally/missing button.h:
There are some git submodules, so make sure to use git and use the appropriate options to get those, e.g.: Using submodules in Git - Tutorial

All my automated builds on github are expired, so I started a new one, get a binary from: CI · void-spark/[email protected]
You will need to choose one that matches your setup, so at least CU3, firmware-esp32-cu3-std should best match your setup.

Pins look like a match. Are your light/motor power signal active high or active low? Might need to adjust ion1/sdkconfig.defaults.esp32 at master · void-spark/ion1 for that depending on it.

You have a motor connected? I see a motor board, so I guess yes. Without a motor to talk to it will just sit and wait

After that you'll have to start watching what happens on the bus, collect serial dumps using the diagram from the first days: Zweiter Frühling für ION-Antrieb --- Sparta, Batavus, Koga ... Use a serial to usb adapter that doesn't draw power to light a led from the serial side, as the bus doesn't have the power for that

 

[dvjcodec]

I look to firmware, but I can't find any line, where I can choose matched setup for this board :/
Where is setup line?
Can U precompile firmware and put all nececery files to upload it via web-tool?

You can click here when you follow the link (CI · void-spark/[email protected]). It should give you a zip with the 3 files you need.
Make sure you're logged into GitHub
If it still gives you trouble I can upload the zip

Got it Thank you. Firmware uploaded, tested under web-tool - compilation from 25 may 6am
Test results:
- system power on (29V charger connected to test)
- display show 0% battery
- light output ON (led flash)
- motor output turn on for a moment and off, and pending off all the time
- motor boards connected direct to power, without relay to test
- pressing BOOT, choose Calibration under menu - no data change on display (but I think mileage from motor boards should be visible)

 

[Mike747]

but I think mileage from motor boards should be visible

The toprun motor probably does not store mileage in the motor (it gets stored in the pmu2/nimh battery).

 

[dvjcodec]

I found in config mismatch with battery pin. Current PCB use 34, in sdkconfig I found 35


# CONFIG_ION_CHARGE is not set
CONFIG_ION_CHARGE_PIN=35

Battery show 0% because (probably) connected 29V power supply. Voltage divider onboard 10/100kOhm give 2.63V to ESP32 pin. Tomorrow I will test with 42V power supply.
Now I saw, 42V battery (full 10S) and divider 10/100 give 3.818V to ESP32 pin. It should be recalculated for 10S battery.

That suggests your circuit is active high (high signal is on), and the software is set to active low,
that's the CONFIG_ION_RELAY_PIN_INVERTED setting

- motor boards connected direct to power, without relay to test
- pressing BOOT, choose Calibration under menu - no data change on display (but I think mileage from motor boards should be visible)

I found in config mismatch with battery pin. Current PCB use 34, in sdkconfig I found 35


# CONFIG_ION_CHARGE is not set
CONFIG_ION_CHARGE_PIN=35

That's a different pin, it's a feature for another user, you don't want to change that I should change the default from 35 for that one to be clearer though.

ADC is always a bit confusing, because you don't set the pin directly, you set the ADC channel, which is tied to a specific pin.
Right now it's hard-coded to ADC1_CHAN ADC_CHANNEL_7, which is pin 35, so it doesn't match the PCB.
Fortunately ADC1_CHAN ADC_CHANNEL_6 is attached to pin 34, so I'll need to make the ADC channel configurable, that's not too hard.

Battery show 0% because (probably) connected 29V power supply. Voltage divider onboard 10/100kOhm give 2.63V to ESP32 pin. Tomorrow I will test with 42V power supply.
Now I saw, 42V battery (full 10S) and divider 10/100 give 3.818V to ESP32 pin. It should be recalculated for 10S battery.

I can do the changes tomorrow, and add a dvjcodec configuration
Let me know if the light and motor pin need to be active high or active low though

 

[void-spark]

Looking at the schema, I think those mosfets allow current to pass on a high input, so it would have to become:
CONFIG_ION_LIGHT_PIN_INVERTED=n
CONFIG_ION_RELAY_PIN_INVERTED=n

@dvjcodec Ok, see how you get on with the dvjcodec build from here: Add dvjcodec configuraiton · void-spark/[email protected]
It incorperates the changes mentioned in my previous comments.
You need to click firmware-esp32-cu3-dvjcodec
