Hi Evangelos,I spent today trying to get an ooPIC I2C example working with the WC-132. 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)?

I'll see if I can work something up for you. But, we're closed the rest of the week for our Thanksgiving holiday.-Pete _______________________________________________ WheelCommander mailing list WheelCommander@xxxxxxxxxxxxxxxxx http://list.nubotics.com/mailman/listinfo/wheelcommander Nubotics Website: http://www.nubotics.com _______________________________________________ WheelCommander mailing list WheelCommander@xxxxxxxxxxxxxxxxx http://list.nubotics.com/mailman/listinfo/wheelcommander Nubotics Website: http://www.nubotics.com
