Code Source for i2C LTC2499 24 Bit 16 Channel ADC, Where to Start?

Looking for pointers to any references or code source for connecting this ADC. Was able to find SPI Version here: http://www.stevenmerrifield.com/tools/imp/spi-adc.nut

Any tips on how to start writing my own would also be greatly appreciated. Looking to get the first i2c.write command to return 0 instead of -1

Thanks Imp Forum!

If all the CA pins are low, you should be able to address it at (0x14<<1).

-1 tends to indicate it couldn’t get the bus though. Do you have pull-up resistors on the I2C bus?
