< I am using 8 ADS1256 adc's in a board and through FPGA reading the output to microcontroller on multiplexing basis
but whatever command I give ADC gives output as 00 even no data is coming on DOUT pin.
even I am not able to read configuration registers > <please give some hints to solve this problem>
The analog side of a 24bit ADC is far more likely to be damaged by ESD than the backend computer interface.
If D0/CLKOUT/DRDY are signals that are expected to be driven by the ADC, have you made sure that it is infact the ADC that are driving them, so the FPGA doesn't do something weird?
Without looking in your data sheet: Is DRDY a signal that should change based on the baudrate, or is it a signal that should change whenever a new sample has been converted and is possible to read? If the second, then the DRDY frequency should normally not be affected by the baudrate.
d0 clkout is not connected to FPGA so no chance of driving that pin by FPGA And regarding drdy, signal on power up it shows a periodic signal of particular period depending on the data rate . Why it is like that I don't know
Initially on power up itself, DRDY pulse starts coming please anybody tell me what may be the possible reason of this. I am getting a continous pulse on drdy.
It means that the ADC is continuously making conversions, and the signal informs when a conversion is ongoing, and when data is available. Every time the signal goes low, it informs that a new conversion is started.
This information is available in the datasheet.
hi all i have to interface the ADS1256 with msc1210 microcontroller but i have no idee for the way to use it! could you help me thanks
The links to the datasheet & manufacturer's product page have already been given - that would be the place to start!
Also, I think the msc1210 is an 8051-derivative - not 80251?
yes it is the same !!have you got some example?
