TFmini 360°(almost) lidar

geofrancis · August 16, 2022, 2:24pm

@count74 I have a version of your code up and running but using a servo and sonar rather than a stepper and lidar, the plan is to eventually use it underwater.

after a lot of messing around i have something working but i can only get the 8 segment display on mission planner, how do i get the 72 segment display?

how do I get this?

int pothigh = 700;
int potlow = 300;

int res = 2;
int FOV = 120;


int potiValue = 0;
 //multiple of res and even(res is 3 degree for the TF02-pro)
int lidarAngle = 0;

@ppoirier any ideas?

I think this might be it.
