Definition at line 232 of file LT_I2CBus.cpp.
void LT_I2CBus::quikevalI2CInit | ( | void | ) |
Initializes Linduino I2C port.
Before communicating to the I2C port through the QuikEval connector, you must also run quikeval_I2C_connect to connect the I2C port to the QuikEval connector through the QuikEval MUX (and disconnect SPI).
