REXLANG problem with Open function for I2c device

Hi guys,
I used i2c_bus_handle = Open(67); for opening I2C bus but compiler need more arguments for this function.
I tried to lookup example but examples have the same declaration.
Can you help me with declaration Open function for I2C device in version 2.50.1.7567?
Thanks

Hi radovanciz,
in REX version 2.50.1 you should use

i2c_bus_handle = OpenI2C("/dev/i2c-1");

See e.g. this example on reading the MCP3422 ADC.

Best regards,
Jaroslav
