Hi Mauro,
I was able to test your patch with vivid sdr tone generation. It calls
sin/cos functions with radians as argument. I find that the sine wave
generated using fixp_sin32_rad() show discontinuities, especially around
90, 180 degrees. After debugging it further, these discontinuities seems
t
The cos table used at fixp-arith.h has only 8 bits of precision.
That causes problems if it is reused on other drivers.
As some media drivers require a higher precision sin/cos
implementation, replace the current implementation by one that
will provide 32 bits precision.
The values generated by t
