We have received an Analog Discovery 2 board and by the initial trials some questions have arised which we hope we can receive the answers from this forum:
How to use Discovery 2 board to sense sinusoidal voltage signals other than the scope data. What we are trying to ask is we want to use the board to send the sensed signals to FPGA and perform a closed loop control. Is that possible with this board. If yes kindly help to perform the exact procedure.
We tried to do the above mentioned with the data logger option of the waveform software there were two issues. First we were not able to use the data logger to capture the signal values for a sine wave instead it only showed the RMS value. Secondly we were unable to update the data below 100 ms. Now for our application i.e. a closed loop control of a PWM converter with a switching frequency of 20 kHz, we want to utilize a double update scheme in the FPGA which will require an update rate of 25 microsecond. Is that possible with this board. Also for a three phase 3 wire inverter we require 5 signals to be sensed and with the data logger we found only two channels. Is there any way to fix these issues.
Now if the answers to the above questions are no can we kindly know which board would give these features and help us perform the desired control via the board interfaced with the FPGA.
If the community can kindly help and let us know how we can fix these problems we will be very thankful.
