Add CS1 Host support for Arduino board type auto-detection (mega 2560 and 1280) #13

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Arduino MEGA 1280 can not be connected with CS1 host in Linux.
It is possible with MEGA 2560.on both boardfs i have the same firmware.

after copiling CS1 with 1280 connected ther is no device shown in the "Serial 
Port" frame.

dmesg | tail for MEGA 1280 says:
**********************
[ 1778.229420] usb 7-1: new full-speed USB device number 5 using uhci_hcd

when Pressing "Connect" in CS1 the following appears:
************************************************************************

********************************************************************

What steps will reproduce the problem?
1. Connect an Arduino Mega 1280 to the Host-Computer
2. Compile CS1 with make
3. Press "connect" in CS1

System specifications were the error occur?
  Operational System: Ubuntu 12.04 AMD64
  Video Board Model: Ati HD 4890

This is because The CS1 Host software only looks for the ACM prefix. I need to 
add a check for USB prefix as well. That should fix it!

OK. got it to work by adding following lines in __init__.py . beneath the line 
122 i added the following lines:       
            try:
                com = "/dev/ttyUSB%d" % each
                if 'win' in sys.platform:
                    com = "COM%d:"% each
                serial.Serial(com)
                self.comList[com] = com
            except:
               pass

Of course as i am not a coder i dont know if this could make a new problem. but 
for now it seams to work with both (MEGA 1280 and MEGA 2560). Hope that u can 
use this

Best greets

Martin

I tried to upload firmware to the MEGA1280 with the "Upload Firmware" Botton 
but got timeout errors.

researched a bit in the net and fond a solution: 

the arguments for avrdude had to be changed to the following:
'avrdude -D -C firmware/avrdude/avrdude.conf -q -p atmega1280 -P %s -c arduino 
-b 57600 -U flash:w:firmware/bin/firmware.hex:i'

then of course the upload to Mega2560 didnt work any more. so i added an if 
...: else ...: action to checkout what kind of Board is connected.

The final result looks like:
def uploadFirmwareAction(self):
        self.currentCom = str(self.coms.currentText())
        self.disconnectSerial()

        if 'win' in sys.platform:
            avrdudePath = os.path.join( 'firmware', 'avrdude', 'win32' )
            avrdudeCfg  = os.path.join( 'firmware', 'avrdude', 'win32','avrdude.conf' )
            avrdude     = os.path.join( avrdudePath, 'avrdude.exe' )
            os.environ['PATH'] = "%s;%s" % ( avrdudePath, os.environ['PATH'] )
            if os.system('%s -D -C %s -q -p atmega2560 -P %s -c stk500v2 -b 115200 -U flash:w:firmware/bin/firmware.hex:i' % (avrdude, avrdudeCfg, self.currentCom) ):
                raise Exception("Error uploading firmware to arduino.")
        else:
            if '/dev/ttyUSB' in self.currentCom:
                if os.system('avrdude -D -C firmware/avrdude/avrdude.conf -q -p atmega1280 -P %s -c arduino -b 57600 -U flash:w:firmware/bin/firmware.hex:i' % self.currentCom ):
                    raise Exception("Error uploading firmware to arduino.")
            else:
                if os.system('avrdude -D -C firmware/avrdude/avrdude.conf -q -p atmega2560 -P %s -c stk500v2 -b 115200 -U flash:w:firmware/bin/firmware.hex:i' % self.currentCom ):
                    raise Exception("Error uploading firmware to arduino.")

        self.connectButton()

at the research in the net i found a little type-error mistake in your code.
-cstk500v2 should be -c stk500v2
i changed that too in the windows-upload-firmware-action-code-snipped but dont 
know how to test it because i dont know how to compile CS1 in linux for 
windows. and of course i dont know how to implement the 2560/1280 checking in 
the windows-upload-firmware-action-code-snippet. but i will try to find out now.

ok got no clue how to check for arduino-boardversion in 
windows-upload-firmware-action-code-snipped.
what i can say is that:

the driver for the mega1280 in windows is from FTDI and is located in 
c:\windows\system32\drivers\ name: "ftser.sys"

the driver for mega2560 in windows is from Arduino LLC and is located in 
c:\windows\system\drivers\ name: "usbser.sys"

maybe a checking for the used driver in the 
windows-upload-firmware-action-code-snipped could do the trick.

on the net i found a good example code for checking the boardversion ( 
http://totaki.com/poesiabinaria/wp-content/uploads/2011/07/sconstruct ).

but i cant implement and try that because as i mentioned above i dont know how 
to compile cs1 for windows in linux. so no chance to test my code in windows or 
wine.

hope this helps!

Best 

Martin

Thanks for the help, Martin!!!

The only way I could find to detect the board type is by using avrdude to 
retrieve the signature ID:

    avrdude -c stk500 -p m2560 -P /dev/ttyUSB0 

this command line should return this:

    avrdude: AVR device initialized and ready to accept instructions

    Reading | ############################################### | 100% 0.02s

    avrdude: Device signature = 0x1e9801

0x1e9801 is the device signature for a mega 2560 board.If you run this command 
on your 1280, you'll probably see this:

    avrdude: AVR device initialized and ready to accept instructions

    Reading | ############################################### | 100% 0.02s

    avrdude: Device signature = 0x1e9703
    avrdude: Expected signature for ATMEGA2560 is 1E 98 01
                 Double check chip, or use -F to override this check.

As you can see, it retreives the device ID of your board, which can give a clue 
to the host of WHAT board type you have an what command line to use! ;)

It's kinda "hacky" way to detect, but it should work for this cases. 

I'll add this check to the main host trunk asap. 

thanks for the contribution, Martin... really appreciate!!
