I'm now using the arduino uno as the voltage generator, connected with a DAC converter, AD5504, Analog Devices, and an operational ampli fier (OPA551, Texas Instruments) circuit to generate voltage output for piezoelectric firing.
The pin assignments are:
piezo_select = 3; //Relay that switches between piezos
go_button = 5; //piezo/wire button
clr = 6;
sync = 10;
ldac = 7;
alarm = 8;
r_sel = 9;
The hardware was previously designed by a former engineer in the group but has left. It functions well in arduino platform, but under the labview code I made there is no voltage output at all (no error given however). Could you please have a look at the vi and find the solution?
I have been struggling on this for a couple of days and really frustrated. It has to be solved really in limited time.
