@felmue ..Thanks for that a colleague sussed that out just before I read your reply but many thanks as you were dead right... as all up and running now. For anyone reading this reply the illumination of the centre main on/off button is LED #4 I didn't realize that the LED's are multi colour until I studied the circuit diagram/schematic ...cool !

Hello @FLOSCH

the reason battery level, power, voltage and current are incorrect is that the calls to GetBatteryLevel(), GetBatPower(), GetBatVoltage() and GetBatCurrent() are happening before I2C is initialized and therefore return invalid values. You'll need to do this calls inside setup() and after M5.begin().

Thanks
Felix

Hello M5Joe,

did you find any way to update the GRBL to 1.1 ? I am also stack on the same problem.
Thanks to any feedback.

Best regards,

Hi,

Sometimes I find IPX (or I-PEX or U.FL?), sometimes MCX, sometimes SMA... on descriptions

So I link them all here... so you can find out yourself

SMA wikipedia the most common one, it is threaded

MCX wikipedia snap in

IPX I-PEX U.FL wikipedia very tiny, mostly used on little pc board connections, surface mounted, snap on

For antennas, you could do an internet search with keywords: "868 MHz antenna"

Also YouTube is a nice source for searching all these terms

LoRa module video on YouTube at 2:00 minutes it shows internally U.FL connectors, and externally MCX if I am not mistaken

@sippanan_p

It seems that your band frequency is OK for US, so do not worry about setting the RX window?

Maybe not able to join has another cause?

@ajb2k3 Good to know. Thanks!

Would love to know if there is a fix to have this work with the core2. I just purchased a core2 and the driver module, just found your post after many failed attempts with the same error you got.

Hi.
Excuse me I checked the documentation and also the github of M5Stack and I couldn't find the "MODULE_4IN8OUT.h" library can you provide me with the URL of the Library plss.
Thanks

For anyone finding this. I contacted M5 and they suggested the odrive module, but that's currently out of stock.

I've moved on to trying to use either a stepper motor or a servo for my application and I think I can make them work.

Bump. Me too! I can't find an M5 copy of MLX90640_API.cpp and MLX90640_I2C_Driver.cpp. After commenting out calls to MLX90640_BadPixelsCorrection() I tried using Sparkfun's version, but the .ino file has calls to interpolate_image() and get_point() which the Sparkfun library does not have.

I tried using Blockly but the data returned by the calls to unit.get(unit.THERMAL, unit.PORTA) objects return garbage data. Well, not quite garbage - it's data but it is not corrected and interleaved in a way I can figure out.

Micropython might be a better bet but I don't know how to get the Unit libraries. I don't have a spare Arduino to test on either.

@jptalledo

I have noticed it drains the battery of the M5Paper quite quickly. I have not tested that specifically as it was not a requirement for my project. The range is quite good at 50-70 cm.

I think there is a way to change the power and read strength, though I have not investigated too deeply. I am using other methods to alter read time. When I get to a stable point I will refine some more.

Hello @thop

in UIFlow online check out Base - Motion. On the Python tab you'll see how to use it with MicroPython.

Thanks
Felix

Yes, you would send position or speed values to each channel.

There should be an example in the documents.

If I misunderstand let me know and I will research further.

Arduino IDE, no problem, and I’m sure it is facilitated in UIFlow.
