public I2c(int i2cFrequency)
i2cFrequency - the frequency of the I2C connectionpublic I2c(int i2cPort,
int i2cFrequency,
int i2cTout)
unit - 0: standard port, 1: target port when availablei2cFrequency - the frequency of the I2C connectiontout: - timeout in ms (in case of clock stretching), -1 for default.public int readBytes(int address,
byte[] buffer,
int length)
address - the address of the targetted slave devicebuffer - the buffer that will receive the datalength - the number of bytes to readpublic int writeBytes(int address,
byte[] buffer,
int length)
address - the addresso of the targetted slave devicebuffer - the buffer to writelength - the number of bytes to write (should be less or equal to buffer.length)
