My Duinomite Mega Canview V4 equivalent Project

Hi Syn,

If you wanted to you could order the UBW32-MCC-PCB in kit form and build it yourself and any basic program I write for the CGcoloumax1 should work but I have been informed that the CAN is untested. It should be cheaper I guess. So you or anybody else who reads this thread could be the first to test the CAN.

 

I have just uploaded the latest version of my BASIC program for the Duinomite Mega Canview V4.0 BMS+. It is located in the first post of this thread. It includes amendments and improvements by [email protected] | PriusChat.

Below is my readme.txt file.

DISCLAIMER - USE AT OWN RISK
WARNING: Watching the CANVIEW v4.0 screen whilst driving is dangerous and any subsequent accident due to not watching the road is entirely your fault. The police can charge you with negligent driving as a result of doing so. So be warned.....do not watch the CANview V4.0 LCD screen whilst driving!!
CANVIEW V4 - WWW.HYBRIDINTERFACES.CA

Based on the original Canview V4 by Norm Dick
This version by [email protected]
This BASIC program is intended for a Duinomite Mega using a keyboard and a VGA monitor.
At a later date it will be updated for a touch screen as shown here
The Back Shed: Small VGA monitor
Setup for BMSplus end voltage range 195v - 235v in 5v steps (default value is now 235volts).
When R1-R4 = 0 relay is energised.
The HV battery fan speed runs in either:-

auto - controlled by HV battery temperature limit i.e. 25degC or
Manual - set speed by pressing number 1 to 6 on keyboard to change speed
In manual it will run at a speed lower than 6 for a fixed period of time and then
automatically change to 6 being maximum speed.

The files i.e. autorun.bas and logo.bmp are available for free @ WWW.Priuschat.com at
My Duinomite Mega Canview V4 equivalent Project | PriusChat
This basic program autorun.bas is compatible with using mmbasic V4.2 with
John Harding's CAN COMMAND implementation available for free at
http://priuschat.com/attachments/duinomite-canb2-zip.42794/
or
http://geoffg.net/Downloads/Maximite/MMBasic%20with%20CAN.zip
Both files (autorun.bas and logo.bmp) must be stored in the root directory of the microSD card of your Duinomite Mega.
The program is saved as "AUTORUN.BAS" as it will be loaded and will run automatically
from the micro SD card and must be saved into the root directory on the micro SD card. Any other
file name has to manually loaded and executed.
If you press the "t" key on your keyboard at bootup you can run the program without
the Duinomite Mega board having to be hooked up to a live CANbus port. It will skip the intro and
will not wait for CANbus data.
Canview V4.0 Basic Program Pages
Keyboard button - page description
F1 - EV man/auto
F2 - Enginer Converter 1 button AUTO/OFF
F3 - Enginer Converter 2 button AUTO/OFF
F4 - PHEV/ORIG
F5 - OEM Nimh cell voltages
F6 - OEM NIMH cell resistances
F7 - Plot a graph, press F7 again to select two variables to plot.
F8 - Data analysis page.
F9 - Data logging page. Press ESC to finish logging. Data is saved to DATA1.CSV, DATA2.CSV,DATA3.CSV,DATA4.CSV and DATA5.CSV.
You can navigate between pages whilst data logging but you can only END logging on F9 page by pressing the ESC key.
Data logging is now appended to data files. A date$ and time$ stamp is included at start of each data logging session.
The date$ and time$ value will be lost when Duinomite Mega is powered down and will change to default values (Year 2000, time 00:00:00)when powered up unless a Lipo battery is plugged into the Duinomite Mega JST connector.
The LiPo battery with 3.7V 1400mA capacity and JST connector for DuinoMite-Mega is available from Olimex. At maximum frequency with a VGA monitor connected the consumption is 125mA which will allow the DuinoMite-Mega to run about 10 hours on battery.
A asterix will blink on every page when data logging is active.

F10 - HV battery fan AUTO/MANUAL speed button. Press 1 to 6 on keyboard when in manual mode.
to adjust speed when in MANUAL.
F11 - get DTC codes.
F12 - clear DTCs
s - BMSplus H555 canbus message
p - PSD page - Power Split Device.
t - Temperature page
q - quit
z - Test pages showing values of unsolicited PIDs.

It is a bit confusing. There are software pin numbers which corresponds with actual GPIO pin numbers.
There is a GPIO mapping table.

Relay 1 is actually on pin 12 (software pin 15).
Relay 2 is actually on pin 14 (software pin 16).
Relay 3 is actually on pin 16 (software pin 17).
Relay 4 is actually on pin 18 (software pin 18).

So my basic program refers to software pin number. The actual GPIO pin number is different except for pin 18 they are the same pin number. Clear as mud?

 

So for our touch screen program we need four analogue inputs, one digital output and a digital interrupt input.

Say we use

Software pin 1, external pin 21 as analogue input
Software pin 2, external pin 19 as analogue input
Software pin 3, external pin 17 as analogue input
Software pin 4, external pin 15 as analogue input

Software pin 5, external pin 13 as interrupt input

Software pin 11, external pin 4 as digital output

We change the code below to:

1. Use a multimeter on ohms selection to identify the resistances between X1 and X2 / Y1 and Y2.

2. Wire the touch panel as shown below.

Y1 connects to software pin 1, actual pin 21
Y2 connects to software pin 2, actual pin 19
X1 connects to software pin 3, actual pin 17
X2 connects to software pin 4, actual pin 15

All power comes from the digital output.



3. Test TassyJims program to verify it all works.

4. Add TassyJim's program to my basic program. Leave out the "main loop" main program as shown below. Just need to use the two subroutines.

Good observation. I will include it in my next update. Will try to make an update at least once monthly.

 

Good luck with that one.

 

I think that what JDH2550 might be saying is that mmbasic is too slow to keep up with the transfer of CAN messages from one CAN port to the other. Programming in C or assembly language would be a lot faster. So if this is the case then even if having two CAN ports would be trivial if mmbasic was too slow.

 

Today was another scorcher in Sydney Australia. My outside temperature reached 48 Deg.C (118.4 F) which for me is an all time record. I drove to work in OOG mode with the A/C running for 40 mins (A/C set at 25deg.C). See photo below. "IT1-??:16DEg.C" is B/S which has never changed and will be removed in the next update.

P.S. The ICE never ran today and the ECT is 52 deg.C, if the ICE started it would skip warm up as it is already at 52 deg.C, wow!
