Nice vid Joerg!

Hallo ich habe ein paar Fragen zur ESC32 V3 und würde mich freuen wenn sie mit jemand beantworten kann. Es sollte recht schnell zu beantworten sein

1. Ist die Software der ESC32 V3 wieder OpenSource? Wenn ja, wo kann ich sie finden? Gibt es ein Code Repository?

2. Unterstüzt die ESC32 V3 hardwareseitig auch BLDCs mit Hall Sensor Interface? Falls nein, sind die obligatorischen Pins dafür noch frei, so das man es selbst anlöten und softwareseitig implementieren kann?

3. Die Hardware bleibt weiter closed source? Gibt es dennoch eine Tabelle mit der Pinbelegung des Mikrocontrollers, also an welchem Pin welche Funktionalität (CAN, BLDC Phasen, etc ...) liegt, um eigene Software für diese Hardware programmieren zu können?

4. Die ESC32 V2 Hardware bleibt auch weiter closed source oder wird diese mit Erscheinen der V3 open source hardware?

5. Ist es möglich, an der Entwicklung der ESC32 V3 mitzuwirken? Wenn ja wie.

Ansonsten gratulation zu dieser Hardware, sie sieht auf den ersten Blick sehr gut aus und ich freue mich schon sie zu testen.

Danke und viele Grüße

I would like to get little help. I want to control two esc32 v3's over serial with other stm32 device. I understand that I can connect only one esc per serial. I would like to get an example code how to do that or the serial library for the esc32 v3.

Thanks

The easiest way is to use the CLI.
Try it out with putty. Then send the commands from your app.

There are two serial interfaces, the CLI as Christof mentioned (the config GUI also has a CLI interface, no need to use PuTTY), and a "binary" protocol which is meant for machine-to-machine interaction. Depending on what you want to do, you can use either or both. None of this is documented anywhere per se, but you can look at the ESC32 v2 source code and other utilities for ideas. Also, I don't know what you're doing exactly, but generating a PWM signal to control the ESC speed should be fairly trivial (use serial for setup/comms/telemetry and PWM for control).

Thanks, Christof and Max

I'm building a robot and I want to use serial because that way I can get telemetry (I could have used CAN, but the CAN drivers for the board I'm using aren't working yet) to my Particle Photon board, which will send the data over wifi to my phone. Also there is a little problem with the servo library for that board, it runs at 50hz and I would have to modify it to run at 450-500hz.

Thanks

There is a problem with controlling RPM. I can control my motors (2-pole inrunners) with duty, but when I try to set rpm, then they will start cogging like hell. I have calibrated my motors to esc.
When the esc is in pwm mode then input frequency is 450hz as I understand, but when it is in uart mode what is the input refreshrate then?
I also have a question about uart connection. Do I have to connect all pins (TX, RX 5V and GND) or can I just connect TX RX and GND, because the board I'm using has only 3.3V GPIO?
