Detailed Description
Function Documentation
◆ i2c_closeConnection()
| void i2c_closeConnection | ( | int | handle | ) |
Close existing connection.
Close connection previously opened with i2c_openConnection()
- Parameters
-
[in] handle File handle returned by i2c_openConnection()
Definition at line 46 of file I2CConnection.c.
◆ i2c_openConnection()
| int i2c_openConnection | ( | const char * | bus | ) |
Set up a connection to the specified bus.
Opens the specified bus in read/write mode
- Parameters
-
[in] bus Path to I2C bus device
- Returns
- Handle to opened bus, or -1 on failure
Definition at line 34 of file I2CConnection.c.
◆ i2c_swapbytes()
| int16_t i2c_swapbytes | ( | const int16_t | in | ) |
Swap word byte order.
Swap the bytes read or written using the SMBus commands
Not sure if the need to do this is a misunderstanding or a documentation issue.
