Dear robo durden, thankyou for this video and the online compiler.. with out these my project would have failed and died...It now works 100% thanks to You!!!
Danke für den Compiler! Ohne den, hätte ich es wohl nie geschafft, die Motoren mit dem original Controller zum laufen zu bringen. Es ist super, so einen Einblick in die Welt der Programmierung zu erhalten. Die Erklärungen in den Files sind auch sehr hilfreich. gruss aus dem Emmental. 😀

Hallo Robo Durden Ich versuche seit ein paar Tagen, die Firmware meines Hoaverboards zu hacken. Ich habe alles versucht. Ich habe zwar eine Hex-Datei von lucyrausch draufgelegt, aber sobald ich das Hoaverboard einschalte, drehen sich die Räder eine Weile vorwärts und rückwärts und dann schaltet es sich automatisch aus. Ich versuche, es mit zwei 100bk-Potentiometern zu steuern, aber das funktioniert nicht.Ich verstehe nicht viel über Programmierung und mein Englisch ist auch nicht so gut. Gibt es irgendwo eine Hex-Datei, die damit funktioniert?
ich bin wirklich kurz davor, alle meine videos zu löschen, weil Ihr alle eh verblödet seid. Es wäre wohl hilfreich zu sagen, welche hex datei Du wo heruntergeladen hast. Aber okay, lucyrausch bietet eigentlich nur eine einzige firmware an und die dreht nun mal nur zum test vorwärts und rückwärts. Jetzt musst Du eigene firmware compilieren. Ist in dem video hier erklärt. Gehst Du zu meinem online compile, wählst die EFeru FOC firmware und aktivierst in der config.h VARIANT_ADC.

Hi! when I try to hit Program&Verify in the target menu it always gives me the error "cannot connect to target! If you're trying to connect to an STM32W1xx device, please select Normal or HotPlug mode from Target->Settings menu. If you're trying to connect to a low frequency application , please select a lower SWD Frequency mode from Target->Settings menu."

How to get more speed using your method?
?? The Emanuel Freu firmware has FOC which gives you about 10-15% more speed at less energy consumption as the original Niklas firmware.
can you help me how to connect Arduino with hoover board wiring diagram and code for Arduino for speed control
Start with the Arduino code on my FOC fork github or the original Emanuel FOC github
Hi, robo durden ! Your video was very helpful to me.
There were many problems, but I finally uploaded the firmware.
One problem is that I want to reduce the maximum speed to a quarter. I'm not good at coding. However, I wonder which part of the source code should be changed. Please.
Emanuel Feru firmware or Niklas Faith firmware ? What control method ?
@@robodurden Emanuel Feru,
and potentiometers for control.
@@andesjose8 you can add speed *= 0.25; in main.c at line 278.
Depending on CTRL_MOD_REQ in line 144 of config.h this will quater the max pwm or max voltage or max torque.
Not really a good idea as the efficiency of the motor is best at 100%.
@@robodurden So, which firmware is efficient? I do not need more than 5 km/h
I know that low speed consumes less energy. I tested it with A-tec's firmware, and it ran for more than 5 hours at 4km/h. With 2 motors
compiling failed :-(
could not parse original config.h
the results of your github robodurden foc..
That's only a message not a compilation error. Just continue and click the 'compile at your risk button'.
And don't be so fearful ;-)

Sir
I want to use bluetooth esp32 and joystick which is usually used in Arduino projects
what variant is recommended
@@bahrulhuda5564 if you want to make use of the steer value than better go with the original Emanuel Feru Firmware.
My fork is only for my variant_uartcar which only need the speed because a car has a steering wheel.
You can connect the two potentiometers of the joystick directly to the hoverboard controller as I have shown in this video.
Or choose a uart communication variant and let the esp32 read the joystick and send serial speed and steer commands.
ahora probare con el firmware de NiklasFauth
too much coffee i think....
I flash with lucysrausch firmware , can i use a pedal instead potentiometer and a button for reverse?
Yes.
@@robodurden my friend
I am looking for your help to make wheels backwards i am use one potentiometer with green wire . I try many time nothing successful
@@YouCantNow learn how speed is calculated in main.c or find a nice variant_xy from the EFeru firmware that already does what you want.
