Flowcode & I2C

I am interested in Flowcode. I have a version 2 development board and would like to connect up an I2C device ( Ultrasound range finder ). I was expecting to connect to a port with pull up resistors and have to bang the bits in assembler. What is the situation with Flowcode? Can I use flowcode and a version 2 board or do I need a new programmer

Thanks

Flowcode produces standard HEX files, so can be used with any hardware.

What about attaching the I2C device. In order to use the I2C facilities of Flowcode. Do I have to add the I2C device to a certain Port, Pins and add pullup resitors etc.

The latest version of Flowcode v3.2.0 (very shortly to become v3.2.1) contains a "master" I2C component which can be used to control slave I2C devices. This component can either use the internal MSSP module of the PIC, or implement I2C in a bit-bang approach. The bit-bang approach allows you to use any pins.

You will need to provide the appropriate pull-ups.

Am I correct in assuming that to use the I2C support I would need the professional version of Flowcode and that it would not be available in the student edition.

Thanks

Yes - you are correct. The free/demo version and the student version both have limits on the components allowed.

Sorry - I should have mentioned this before.
