<![CDATA[How to change the I2C adress of a module ?]]>I want to use 2 COPLUS motor driver moduls for 4 DC motors.
I read in the forum that I have to change to I2C adress via a modification of the firmeware. (change the default adress and burn a new firmware.)
How can I do that ? is there a special software ?
Is there a list of used I2C adresses inside the M5Stack system - so I canfind a "free" I2C adress ?

OR .... is there an easy way to controll 4 DC motors ?

K.D.

It is not the software "M5burner" - this is clear for me - excuse me.

I do not understand "EasyLoader".
This software is mentioned on the top of every documentation and there are different versions for every unit.
But what is the software flashing ? -
I know that EasyLoader flashing "a firmware" - but were is it from and what firmware ?

Is it a kind of update service ?

In one topic of this forum it is said, that I can cange the I2C adress with this software. I have only change a line value inside a file or script ??? no more info.

Do you know more about that software and how it is working ?

Thank you again for your helpful answers.

p.s. I'm exited too about M5Stack and I want to use it in a autonomous vehicle. That's why I'm asking for the use of multiple sensors and motors.

Here is one https://docs.m5stack.com/#/en/quick_start/m5core/m5stack_core_get_started_MicroPython?id=m5burner

I found that table at docs.m5stack.com in the top navigation:

Just a little question - maybe a Dummy question:
How do you know that ?
How do you know that there is an adress like you send me ?

Is there any documentatio I have to go thru - to know all that things ??

Next thing concerning I2C change:
I read, that I should use a software called "M5burner"., It is the same that I find in every documentation in the beginning.
There you should have the possibility to download firmware and flash it.
I tried the software, but I can not find any possibility for download a firmware or a piece of software.
Is there a documentation for "M5burner" ?
