CCS/LAUNCHXL-F28069M: Wiring Lego Mindstorms EV3 with Launchpad + BOOSTXL-DRV8301

Tool/software: Code Composer Studio

Is it possible to wire Lego EV3 Mindstorms with Launchpad F28069m using I2C interface ? Can you please point to any application note to implement this. I want the Lego to act as Master and the launchpad to act as the slave (receive data from lego and forexample: rotate the motor, get data about the motor…) , is it possible for this launchpad to act as slave? I couldn't find any example code for it. Which is easier I2C or SPI for this connection ?

Hi Jinan,

I'm not familiar with the specific IOs available on the EV3, but if you have I2C or SPI and you can get it into a 3.3V CMOS level format you should be able to connect it to the corresponding launchpad IOs.

Both I2C and SPI support slave mode, but I don't think we have specific slave mode examples; you'll have to adapt a little bit from the provided examples in either case.

Hi Jinah,

You can find the bitfield based examples in C2000ware in \device_support\f2806x\examples\c28\.

There is one example of the i2c talking to an EEPROM and two examples for SPI loopback.
