Tool/software: TI C/C++ Compiler
Hello TI!
We are created own-self ToF-bord based on your OPT8221 demo-board.
I try to create configuration file for example for 20, 30 MHz in dealiasing mode.
The parameters ma, mb, ka, kb, freq_ratio are evidence how to calculate.
But I do not understand how rightly chose mod_mx, mod_nx, mod_psx parameters.
Using datasheet, 7.3.5, formula (11) and (12) I can combine TG parameters:
0 <= mod_mx <= 63
0 <= mod_nx <= 3
0 <= mod_psx <= 7
- it is according registers possible ranges.
for first (20 MHz) frequency:
mod_m1 = 10 mod_n1 = 1 mod_ps1 = 3
mod_m1 = 15 mod_n1 = 2 mod_ps1 = 2
mod_m1 = 20 mod_n1 = 2 mod_ps1 = 3
mod_m1 = 30 mod_n1 = 3 mod_ps1 = 2
mod_m1 = 40 mod_n1 = 3 mod_ps1 = 3
for second (30 MHz) frequency:
mod_m2 = 15 mod_n2 = 2 mod_ps2 = 1
mod_m2 = 30 mod_n2 = 3 mod_ps2 = 1
mod_m2 = 45 mod_n2 = 3 mod_ps2 = 2
all lines confirm equation (11) and (12).
Here I can see few variants for configuring TG parameters.
What is the best variant and how rightly to chose it?
For example: In case LongRangeConfig in demo-board:
mod_m1 = 10 mod_n1 = 1 mod_ps1 = 1
mod_m1 = 20 mod_n1 = 2 mod_ps1 = 1
mod_m1 = 40 mod_n1 = 3 mod_ps1 = 1
mod_m2 = 15 mod_n2 = 2 mod_ps2 = 0
mod_m2 = 30 mod_n2 = 3 mod_ps2 = 0
but it is written to register the next:
mod_m1 = 20 mod_n1 = 2 mod_ps1 = 1
mod_m2 = 15 mod_n2 = 2 mod_ps2 = 0
Thank you!
