generate Chirp signal with LabVIEW FPGA

[engkhalid1111]

Dear all, 

I am trying to genrated chirp signal and send it to the fpga using momery read amd wirite. I am using NI-cRI09022 and NI9263 and NI 9215. However, i am facing problem that the signal cannot be genrated on the fpga. I have conecedt the ouput (AO) with input (AI) to test the code and I found there is no signal recivied. Any help will be preaciated,

Do I need to convert the binary to the normal voltage in the target as the voltage in the host vi has been converted to binary?

I have attached the code.

Best regards, 

Khalid

I glanced at your code and the only obvious thing that stuck out to me as being odd were the unwired inputs to the Read/Write node in FPGA_Periodic_Start. The unwired inputs will write the default value for that type into those registers on the FPGA which is probably not what you want.

Also, have you tried simulating this using the Execution on Development Computer options. You can put conditional disables around the I/O and instead write into your own buffers just to test things.

Hi Dragis, 

Thank you  for guiding me. I have wired what you have mentioned and removed the conversion VI that convert the normal voltage to binary. The code starts to generate signal. However, I have tried to read the signal that has been generated through the FPGA. it is not giving me the same signal that I have generated as can be seen in the attached image. Could do you help at this point or guiding me to solve this problem. I have attached the code

Best regards, 

Khalid
