I am using LTC2497. I am trying to get the ADC conversion reading, could anyone explain how does the conversion of 2's compliment to decimal works on this ADC? I tried many times and it does not seem to be working.
Thanks for the promopt response. I tried the conversion...I still didnt get the result..did i missed anything?
After the conversion, it is necessary to send the read address which the LTC2497 should ACK and then read out the data. It sounds like the ADC is not acknowledging the read address you are providing. Can…
With some help, I got to the following step,
I decoded the waveform to derive at "0x14 and 0xB0" which is my ADC address and channel 0. On both waveform, the MCU ACK the values.
I applied 5v to the ADC Channel 0 and it returns "0xC000" which translates to "11".
I am still having issues updating the channel to the ADC. On my serial monitor, it does shows that my channel is updated but it is not the case on the ADC. Any idea what might be the issue?
Yup, I tried and the conversion is correct when my ADC voltage is less than 2.5V.
The problem I am facing is the ADC not responding to the request to change channel. I have no issues reading a single channel but when i try to change the channel, the ADC feeds the value of CH 0 only.
