I'm trying to use MMA7660(on kinetis) with TWR-Sensor module. Without this module, it works correctly, but than i add SENSOR in tower system, it's stop working after few moments (accelerometr stop response). It conneted with I2C jumper configuretion on SENSOR-board. I want to acces other sensors with i2c0, so i connect jumpes on I2C configuration jumper on 1-3 and 5-7. And it doesn't work. 7660 sendor are removed from sensor board.
