Powered Up with ESP32, hub and remote

[Lok24]

Hi all,

just finished my first tests with the M5stack ATOM Matrix and the legoino library.

A little program is installed to connect a hub and a remote control, you can choose between two profiles how they shold act.
Profile 1 is like the app or remote with a train hub.

Here is a little video (1:34), have fun!

Awesome!

Great work! The ATOM Matrix is a very useful board. I have 5 of this :)

Very nice!!!

Now, I have a question for you, @GianCann and @Lok24:

The Legoino library does not (yet - Cornelius will work on this he said though) support the LWP "StartSpeed" sub command (0x07/0x08) of the output command 0x81. The 2I/O hub supports that - as well as it allows defining "profiles".

As I will not have access to my VB6 programs for some time, where I used already the LWP StartSpeed (Speed, MaxPower, UseProfile) command with MaxPower 100(%) and UserProfile = 0 (no profile), I can't further investigate this right now. The PID controlled speed setting works >really< nice. You set speed to 5% and the hub will control the PUp L-motor to do exactly that. The Crocodile and any other PUp L- or the like motor (but not the train and M-motor) propelled train can be speed-controlled in a very nice fashion. What I like most about this mode is that trains don't slow down in curves and can be reliably operated at very low speeds.

Question is: Once I have defined the profiles in the hub, lets say "slow acceleration" as UserProfile 0 and "fast acceleration" as UserProfile 1 do these stay in the hub's memory or do I need to define them every time I turn on the hub?

Thanks in advance!

All the best,
Thorsten

My hub starts motors always "normal", even whena  profile was used before.

So I would assume: not stored permanently.

@Lok24 Thanks a lot!!!

BTW - had to migrate to my old Dell Precision M4700 because I dumped some white wine on my Dell 7530 ... cat1 (brother, Romeo) was chasing cat2 (sister, Giulietta) like crazy, I exploded from my chair, so did the white wine, all over the keyboard, a blink later it went dead and a moment later there was a weird sound accompanied by bad smell ...

How-ever ... installed all the updated Arduino stuff along with ESP32 etc etc board managers: Compilation for ESP dev board goes much faster, upload is smoother and faster as well. It is all a matter of tens of seconds.
