Detailed Description
I2C2 Singleton Driver This is a thin wrapper around I2C_Base class and merely gives the base address of the I2C2 memory map.
Member Function Documentation
| bool I2C2::init | ( | unsigned int | speedInKhz | ) |
Initializes I2C2 at the given.
- Parameters
-
speedInKhz
Before I2C is initialized, check to be sure that the I2C wires are logic "1" means that they are pulled high, otherwise there may be a short circuit.
I2C2 is on P0.10, and P0.11
I2C wires should be pulled high for normal operation, so if they are, initialize I2C otherwise disable operations on I2C since I2C has a likely hardware BUS fault such as:
- I2C SDA/SCL with no pull-up
- I2C SDA/SCL shorted to ground
