RE: ADS1015 Communication Problem

Other Parts Discussed in Thread: ADS1015

Hi Bob san or my other friends

- I want to replace analog ADC part with your ADS1015 in our one product...  For intial development purpose , I have mount one ADS1015 with signal conditioning in one general purpose board.   I am attaching the My  schematic along with this thread... I have connect ADS1015 with LPC2388 micro-controller GPIO pin and that two GPIO pin ,I have written code that work as I2C Bus........

- Now When I am reading the ADS1015 then ,  As per the data I am getting my MSB is getting vary as per the Input voltage applied on analog Channel 0 but LSB is not getting vary .... I am getting LSB 0xF every time.... So what could be the reason for this?

- As I have checked on scope ,  MSB byte is getting vary as per the input but , LSB is every time showing high mean 0xFF  ...mean SDA line high for LSB byte....

- Awaiting for your earlier reply...3465.Sch13.pdf
