Hi Pete,

 

I was wondering if there is a dummies guide to = sending/receiving instructions to/from the wheelcommander?

 

For example: (in matlab)

S =3D serial(‘COM1’) *this sets up = the com port*

Fopen(s) *this opens the com port for = communication*

Fprintf(s, ‘Sting goes here’) *this = sends a string to the com port*

Fscanf(s) *this reads whatever has been = transmitted to the com port*

 

Using the above sending and receiving mechanism how = would I send the instruction to wheelcommander to move forward/backward etc, = using a serial(RS232) communication port?

 

Your help is much appreciated.

Unfortunately, the ooPIC software itself does not yet provide raw I2C access via the hardware I2C lines; the only way to communicate using I2C with the WC-132 is using the slow oI2CM object, which shares the I2C bus with the EEPROM that stores the ooPIC user program. I have some hope that I can get it to work, but I'm not sure at this point. It looks like Savage Innovations (makers of the ooPIC) have plans to add hardware I2C access, but it is not ready yet; they currently only use the hardware I2C lines for their oDDELink object, which is meant to communicate with another ooPIC, not a general purpose I2C device such as the WC-132. I think your best bet will be to try to port the Basic Stamp example, which uses serial port access, to the ooPIC. As for your desire to have an example using Visual Basic that does direct serial port writes to the WC-132 rather than use our DLLs, we would rather you just use the DLLs -- they do all the hard work for you. But, if you are required for some reason to bypass them, you will need to research how to access the serial port from Visual Basic, which lots of people have done for other kinds of devices, and I'm sure you can find such an example on the internet. The part that would communicate with the WC-132 would use those example RS-232 Visual Basic access methods to implement the WC-132 protocols. Again, the Basic Stamp example would be a starting point. Not knowing your experience level, I don't know if this is easy or hard for you. Just for our information, is this a school assignment you are working on? -Pete Evangelos Georgiou wrote: > Hi Pete, > > Do you have any good news about my request for assistances in utilizing the > WC-132 via a Microsoft desktop PC serial RS232 port (in Visual Basic 8)? > > Regards, > > Evangelos Georgiou > E-mail: evangelos.georgiou at kcl.ac.uk > > -----Original Message----- > From: wheelcommander-bounces at list.nubotics.com > [mailto:wheelcommander-bounces at list.nubotics.com] On Behalf Of Pete Skeggs > Sent: 22 November 2007 07:15 > To: WC-132 WheelCommander Controller Support List > Subject: Re: [WheelCommander] ooPIC WheelCommander Assisstance Required... > > Evangelos Georgiou wrote: > >> In addition to my question about controlling the WheelCommander via a >> PC using a RS232 serial port; Is there a guide or examples on how to >> use the WheelCommander with an ooPIC via the I2C bus?

My interest in utilizing the WheelCommander is purely personal though. The use of the WheelCommander is to be implemented in my mobile robot to compete in the annual MicroMouse competition, hopefully if I can get the mobile robot to work. It is not fundamental to use the ooPic for the operation of the WheelCommander. But it is paramount that it can be operated via Visual Basic or any other variant in a Windows operating environment. On your advice it seems that the best solution is to use the NdiCmdC.dll. My experience in Visual Basic 8 is limited because I have learnt it on my own but I am able to complete some complex tasks and I'm edger to learn new things. If you do not mind to assist me in setting up the "dll" and sending receiving commands from WC-132, in Visual Basic 8, I would be most grateful. I have looked at the support documents for the "dll" but since I have never done something like this before, I am not 100% sure on how to use this information. I am sure it simple once the understanding is grasped. I have looked at the example provide for Visual Basic 6 but found it difficult to understand. I have also tried to convert the Visual Basic 6 example to Visual Basic 8 but failed and I do not understand the application enough to correct the errors. If you are interested diagrams of the mobile robot has been attached along with a hardware map of the implemented mobile robot. Thank you very much for your help.

Unfortunately, the ooPIC software itself does not yet provide raw I2C access via the hardware I2C lines; the only way to communicate using I2C with the WC-132 is using the slow oI2CM object, which shares the I2C bus with the EEPROM that stores the ooPIC user program. I have some hope that I can get it to work, but I'm not sure at this point. It looks like Savage Innovations (makers of the ooPIC) have plans to add hardware I2C access, but it is not ready yet; they currently only use the hardware I2C lines for their oDDELink object, which is meant to communicate with another ooPIC, not a general purpose I2C device such as the WC-132. I think your best bet will be to try to port the Basic Stamp example, which uses serial port access, to the ooPIC. As for your desire to have an example using Visual Basic that does direct serial port writes to the WC-132 rather than use our DLLs, we would rather you just use the DLLs -- they do all the hard work for you. But, if you are required for some reason to bypass them, you will need to research how to access the serial port from Visual Basic, which lots of people have done for other kinds of devices, and I'm sure you can find such an example on the internet. The part that would communicate with the WC-132 would use those example RS-232 Visual Basic access methods to implement the WC-132 protocols. Again, the Basic Stamp example would be a starting point. Not knowing your experience level, I don't know if this is easy or hard for you. Just for our information, is this a school assignment you are working on? -Pete Evangelos Georgiou wrote: > Hi Pete, > > Do you have any good news about my request for assistances in utilizing the > WC-132 via a Microsoft desktop PC serial RS232 port (in Visual Basic 8)? > > Regards, > > Evangelos Georgiou > E-mail: evangelos.georgiou at kcl.ac.uk > > -----Original Message----- > From: wheelcommander-bounces at list.nubotics.com > [mailto:wheelcommander-bounces at list.nubotics.com] On Behalf Of Pete Skeggs > Sent: 22 November 2007 07:15 > To: WC-132 WheelCommander Controller Support List > Subject: Re: [WheelCommander] ooPIC WheelCommander Assisstance Required... > > Evangelos Georgiou wrote: > >> In addition to my question about controlling the WheelCommander via a >> PC using a RS232 serial port; Is there a guide or examples on how to >> use the WheelCommander with an ooPIC via the I2C bus?
