Sawtooth wave generation on Labview FPGA (Flex Rio 7966)

[Mahesh0459]

Hi sir, I have to generate a sawtooth wave on Labview FPGA in sctl (40Mhz clock). I have tried many methods nad even used FPGA DDS wave Generated. I am getting square wave as output although lookup table is sawtooth . I am attaching the code. Please look into that and help me in generating Sawtooth on FPGA.

Thanks in advance..

Take a look at this code.  It should be able to be ported to the FPGA.  If it needs to range only positive, replace the negative peak value with zero.
