Antenna Track Model-3D #85

Open LZ-3D opened 2 weeks ago

LZ-3D commented 2 weeks ago

Hi, I'm Luca, I've been working on my antenna track project for several months, now that it's time to program it I came across your project.

So I'll show you my results, 3D modeling of the antenna.

For control I use an esp32 tft display, with gpio expansion and two drivers for nema17 with minimum and maximum limit switches.

the goal is to make the most of the MLRS telemetry for tracking, and capture the analog or digital video signal as best as possible and send the telemetry to the PC with Mission Planner via wifi.

My project is not yet public but it will be soon.

now I try your code, I'd like to collaborate with you.

Hi Luca, your project looks very nice and of course I would like to collaborate with you. You say you have limit switches on the steppers, so we might need more available gpio pins on the mpu. The moba library I use can set and remember an arbitrary "start" position within a session, so strictly speaking we don't need limit switches. Also, sometimes the shortest angular distance to the desired angle is sometimes the opposite direction past where the limit switch would be.

I look forward to hear from you.

I put the limit switches because if the belt slips on the pulley the motor is convinced that it is in a position that in reality is not exact, so if it presses the limit switch the max. and min. limit are calculated again.

for the gpio ports I use MCP23017 16 EXPANDER and for the display it is the one with esp32 the model is 2432S028 at the moment your code compiles correctly, in the next few days I will connect everything and try it, the project is continuously updated.

Looks like you know what you need to do. I assume the two helical antennas are for video, and the Maxon is for control, maybe 900 MHz? Very nice. Let me know how it goes.

there are some protocols in your sketch that don't work, at the moment I abandoned the display with esp, because it has few gpio, so I redid everything as in the photo, I also eliminated the stepper motors, I'm waiting for the 30kg servos. I'll keep you updated. IMG_20241009_233845

Thank you for the feedback. It would be useful if you could provide details and debugging data about which protocols don't work.
