My Duinomite Mega Canview V4 equivalent Project

Thanks for the info. I have been busy building a 40ah A123 battery pack.

Can you put your changes to the Basic code in bold. So I can clearly see what you added.

Have you found anything by logging the DTCs.

 

Yes, I have been taking photos and I will make a post on the other thread "Planning Canview and BMS+ conversion with Lithium". There are other documented conversions on this thread by Planetaire, Mr Plugin and FWD. Planetaire has the best Conversion for a 20AH A123 pack.

It is still early days. I still have a long way to go.

The A123 20AH cells supply in China has dried up. I had to accept A123 cells with no markings.

 

OK

 

I have made an update to the basic program. I found a bug. The subroutine for inversebyte is incorrect, only half the code works.

Code:

inversebyte:
  If bmsvolts = &HC3 Then voltsbms = &H3C : If bmsvolts = &HC8 Then voltsbms = &H8C
  If bmsvolts = &HCD Then voltsbms = &HDC : If bmsvolts = &HD2 Then voltsbms = &H2D
  If bmsvolts = &H7D Then voltsbms = &HD7 : If bmsvolts = &HDC Then voltsbms = &HCD
  If bmsvolts = &HE1 Then voltsbms = &H1E : If bmsvolts = &HE6 Then voltsbms = &H6E
  If bmsvolts = &HEB Then voltsbms = &HBE
Return

It should be:

Code:

inversebyte:
  If bmsvolts = &HC3 Then voltsbms = &H3C  'PHEV mode 195v
  If bmsvolts = &HC8 Then voltsbms = &H8C  'PHEV mode 200v
  If bmsvolts = &HCD Then voltsbms = &HDC  'PHEV mode 205v
  If bmsvolts = &HD2 Then voltsbms = &H2D  'PHEV mode 210v
  If bmsvolts = &H7D Then voltsbms = &HD7  'PHEV mode 215v
  If bmsvolts = &HDC Then voltsbms = &HCD  'PHEV mode 220v
  If bmsvolts = &HE1 Then voltsbms = &H1E  'PHEV mode 225v
  If bmsvolts = &HE6 Then voltsbms = &H6E  'PHEV mode 230v
  If bmsvolts = &HEB Then voltsbms = &HBE  'PHEV mode 235v
Return

I have added a warning for a depleted battery that will work in either forcedEV mode or PHEV mode and changed the F2 key to enable/disable the warning.

Here is the added code:

Code:

updateWarn()  'main loop
 
If K$ = Chr$(146)  Then F2() ' Forced EV PHEV battery depleted warning switch
 
Sub F2
  ' If R2 = 0 Then R2 = 1 Else R2 = 0
  If Warningpage=1 then Warningpage=0 Else Warningpage=1
  font 1
  If page=0 then
	If Warningpage=1 then Print @(10,370) "Warning ACTIVE"; else Print @(10,370) "			  ";
  Endif
End Sub
 
Sub Updatewarn
  If warningpage=1 then
	If (R4=0 and SoC<=73 and warn=0 and SoC<>65) then
	  page=25 : warn=1 : Gosub warningVGA
	Endif
	If R4=1 then
	  warn=0
	  warningpage=0
	Endif
  Endif
  If page=0 then
	If Warningpage=1 then Print @(10,370) "Warning ACTIVE"; else Print @(10,370) "			  ";
  Endif
End Sub
 
If K$ = Chr$(27) Then
	page=0 : warn=0 : GoSub printHeader : GoSub drawboxes : GoSub drawlabels_lhs : GoSub drawlabels_rhs : UpdateF4()
	counter=counter+1
	If counter=>3 then AHT=0
  Endif
 
WarningVGA:
  If warn=1 then
	cls : Font 2,2,1 : Print @(80,150) "!! WARNING !!"
	Font 2,1,0 : Print @(100,250) "PHEV battery pack depleted"
	Print @(100,300) "Press F4 and then ESC to exit"
  Endif
Return

 

I bought a new Duinomite Mega from Olimexery on Ebay as a back-up and for programming. It comes loaded with DMbasic firmware, I have changed it to MMBasic so it can be used with my program, below are the instructions I made up to download the latest firmware of MMBasic V4.3. It is just a matter of following the instructions below and it is ready to go. The instructions below have been tested and proven with a brand new Duinomite Mega

STEP BY STEP USING A COMPUTER WITH WINDOWS 7 (CANVIEW FOR DUMMIES) 10/04/2013

The Duinomite Mega is delivered with it's own version of basic called DMbasic which we no longer use. We need to install the latest firmware version of MMbasic with CAN by Geoff Graham. We need to dowload two zip files from this website: Geoff's Projects - The Colour Maximite

1. Download "Duinomite MMbasic firmware Version 4.3" (or whichever is the latest version at the time) and also download "Special version of V4.3 with CAN commands (controller area network)" from this website Geoff's Projects - The Colour Maximite. Save it to your desktop.



2. Using the WINzip program (or any other kind of ZIP program) to extract "MMBasic with CAN.ZIP" and save the file "Duinomite_MMBasic_V4.3 with CAN.hex" to your computer desktop.



3. Using the Winzip program unpack the zip file "Duinomite_MMBasic.ZIP" and save the file "BootLoader.exe" to your desktop.



4. Now run the program "BootLoader.exe". Should look like this:



5. Connect the miniUSB cable from your computer to your Duinomite Mega. Now the Duinomite Mega is powered by the miniUSB cable only.



6. Connect miniUSB cable from your computer to your Duinomite Mega. Press the black button on the side of the Duinomite Mega (there are two black buttons, so use the one closest to the USB plug) at the same time as you plug in the miniUSB cable. You should see the green LED and amber LED flashing. This indicates that the Duinomite Mega is ready for firmware download.



7. Using your mouse click the button "Load Hex File". Now should look like this:



8. Using your mouse select the file "Duinomite_MMBasic_V4.3 with CAN". Select the button "Open". Should now see the following:



9. Using your mouse now press the button "Program Device". Now you should see the following:



10 . Now follow the instructions by restarting the device. This can be done by replugging the miniUSB cable.

You can see this Youtube video which shows you how the green LED and the amber LED flash when it is ready to accept a new firmware download (online mode) :

11. Download my latest files to go into the microSD card root directory i.e.http://priuschat.com/attachments/canview_v4_bms-_nc_29032013-zip.48759/. You will need to UNZIP the files. It is attached in the first post of this thread. Note the numbers 29032013 is the date, so use the latest date. Read the readme.txt file included.

The basic program is called "AUTORUN.BAS" and will run automatically when the Duinomite Mega is booted/rebooted or when the Prius READY signal becomes true.

You will also need to purchase a seperate microSD card, miniUSB cable, PS2 keyboard and a VGA monitor.

Good luck!!

 

Video has been updated on first post to show faster updates and the different pages.

 

I guess it is better late than never. I measured about 79.7mA @13.8volts DC = 1.10 watts when the basic program was in standby mode.


I also measured about 105.3mA @13.8Vdc = 1.45 watts in run mode with a VGA screen and a PS2 keyboard..



That is a good low power consumption!!

 

My latest basic program for the Duinomite Mega is now available in my first post of this thread. It includes a few extras.

The default end voltage is now 210v, same as Norm's Canview.

There is a instant clearing of DTC for OutOfGas mode users. After pressing the Prius power button the Canview will do a DTC check and if the OutOfGas DTC is returned it will automatically clear the DTC.

The F2 - "Warning Active" is now visible on most pages.

The PHEV battery Amp Hours is now shown on most pages.

The F3 keyboard button now toggles between most pages for easy access.


Added the highest, lowest, difference and Delta SoC of the NiMH to the F5 page.

Added four time values of battery volts high, battery volts low, battery temperature high and DC inhibit.


Added gauges, self explanatory.

Gauge17 is a bar graph showing OEM NiMH module voltages. 17.3 volts represents the 100% charge value or SoC of 80%. The value of 13.2 volts represents a charge of 10%.

 

Have you tried downloading my latest basic program from the first post dated 30/08/2013. It works with mmbasic 4.3. Let me know if it works with mmbasic 4.4.

 

Maybe increase the ESC count to six (or higher) instead of three to reset the AHT.

Other option is use a different key e.g. F1 to clear the warning page.

Cannot think of a better solution. Let me know if you can think of a better idea.

 

I am using a small keyboard with 21 keys (it fits nicely on top of the cup holder) which does not include a "R" key. Maybe just a confirmation will be suffice.

At the moment I think the best solution is to use the KEYDOWN function which empties the keyboard buffer together with the DO/LOOP function should stop the accidental resetting of the AHT.

 

I have made some mods to the basic program to address this problem. Give it a try for a while and let me know if it works.
Changes:
1. Added

Code:

DO WHILE KEYDOWN AND K$ <> "" : LOOP

This code ignores keyboard input whist the same key is constantly pressed. Also empties keyboard buffer.
2. PSD page is now the main page when powered up. PSD page also shows the temperature of MG2. I figured that the temperature of MG2 may need to be observed when running Prius in OutOfGas mode.
3. When the depleted battery pack warning page now comes up you "Press F4 then F1 to exit" instead of "Press F4 and ESC to exit". Pressing F1 whilst warning is active will not change EV auto/manual mode of F1.

New basic program has been uploaded to first post.
