beta tester wanted

Give a overview from your setup and some photo's.
If you have a PICkit2 from Microchip and can handle Hex files, that an advantage.
Not all the advance functions are implemented yet, but I have a lot of free memory for functions and logo's.

If you have a question about the display, I will answer in this topic

New function: level indication on the right side for all functions

Two comments (and no offense intended, just comments from "10,000 feet", as we say in engineering):

1) You have excess precision on your temp display - two digits is plenty

2) The iconography (bike, battery, etc) seems to take up a lot of screen area (we call this "real estate") - you might consider making the icons smaller

Keep up the good work...

I bet I could beta test that thing for you. I recently finiched a 9C build and have nothing for a meter on it.

I can't email out from work, however, so that would have to wait.

Rough specs are a 700C rear wheel, with a a 9X7 500W 9C motor and 22A controller. Its set up for 37volts now, but I have the capability to run it at 55.5V

That thing is very cool.
I want to get on the beta. Email sent.

Hey Wanders,

The precision is very easy to change, In the setup It will be adjustable, 1 to 8 dig (just for fun :wink: )
The icons are not yet ready, the new icons will be interactif and change depending the value displayed.
example, temp below zero gives freezing symbol.
The avarage speed changes the icon to level,more,less
If there is to mutch information on the display it will be dificult to read.
This display hase 100X32 pixels, those icons are 32X16, there are not many pixels to make a good icon.

What do you like to see more on the display, if there's no icon or just a very small one?
Maybe you have some nice ideas for me

thanks for the advice

dual temp would be nice, one for hubmotor one for controller

does it have a backlight?

 

[karma]

i see it does

This display was to small to read, but the resolution was very nice, 128X64 pixels.
The new display has a green backlight and is larger.

The features I would like as options, alot of these things I have been enjoying with the eagle tree.
2 temp readouts
Selectable display with up to 4 readings.
Data storage(to review at a later date). So you can review things like how the temp went up at 2000 watts for 2 minutes ect.
GPS for speed , and elevation change.
Wireless display.
Cruise control.
Current limiting.
Programmable LVC.
Temp cut off
Computer programmable.

2temp readouts=> I use a temp sensor network DS18B20 from Dallas, you may put 100 sensors on the same connection.
This is good to get the temp reading from every cell

selectable display=> The software for the layout is very easy to adjust, give a sample for the layout and I program it for you....

Data storage=> you can connect a µSD card from max 2Gig for data logging. the information is stored once a second.
this is the old pcb design, the µSD card is on the inside and dificult to take out.

On the new design this µSD card will be an option, you can put this option in 3 way's
Turned inside, so you have to open the case to get the card
Turned outside, true a small hole you can get the card out, but this in not waterproof !!!
Third way is external with a 5 core Wire to a small box to put on the steer.

GPS for speed , and elevation change => I can program a NMEA183 input to one off the option pin's, to connect a GPS module.
Wireless display=> I have a BLuetooht module to put the information wireless on your Smartphone win CE

Cruise control=> Standaard
Current limiting=> standaard
Programmable LVC.=>Standaard
Temp cut off=> optional bud possible to program.
Computer programmable=> do you mean a connection to the computer?

 

[Fishmasterdan]

Computer programmable=> do you mean a connection to the computer?

Yes; so you can D/L the data or configure the display for different looks.

Yes; so you can D/L the data or configure the display for different looks.

It is possible to connect a small USB interface to the computer.
Maybe a better idea,when I use a special setup file on the µSD card, then you can edit this setup file on a PC, put it in the display and load the new settings.
Then you can use different settings who are simple to change.
For a connection to the pc I have to write A pc program for the interfacing.
The problem is that is needs to work under Microsoft... :|
I have wroten software for XP, but Vista gives
.net probs pfffff

Great work!

I would add that a wireless speedo sensor would be nice. Also, the ability to disconnect the display/unit and carry it away so a thief doesn't do it for me.

The display is disconnectable, Just one plug on the back side and you can take it away.

Nice work , it looks like a great project.

I currently use a Watts Up, so I like to see the usual volts, amps, watts displayed simultaneously or cycled through within a few seconds on the same screen along with the speed.

The Watts UP has a Volts limit of 60V, too low IMHO, what does your EBC top out at?

The levels - I assume they are power limits to stay below legal power requirements (eg 200W in Australia), and the max level is unrestricted?

Does it measure regen? (not that I use it, I'm just curious, and you seem to have thought of everything else).
