@aiconnection said in m5stack tough programming help:

@robski can you please guide me resources as to how to work with uiflow 2.0 to setup blocks to read modbus data. I know the communication protocols for my sensor. Being newbie I have no concept of uiflow workability with respect to this unit

Any help or video link would be great

can you read any modbus data from mentioned sensor using any of available modbus test tools? Just to confirm that communication to sensor over modbus is fine.

@lbuque for some reason, the values in my unit were way off when I received it and it did not work. Resetting the values got the unit to work. Not sure what corrupted the values.

Hello @tonyd

I am glad to hear you got it working.

Sorry, no, I don't know what the scroll method does.

Thanks
Felix

@felmue Yes. This time I erased first, and it completed successfully. I reset it afterwards, then put it into download mode again (flashing green led) and then burned the Atom S3R UIFlow image. It burned successfully.

When I clicked the reset button, it found COM4 and COM5 (it usually just has COM4) but still no screen.

Now I think I have it working. I think maybe I assumed it would load a program to the screen for UIFlow, but I guess it doesn't?

Is there a good place to get more S3R programs? I only see the UIFlow one in M5Burner?

@felmue That was it thanks! All working now.

@felmue Hi

Thanks for looking into that.

@teastain Thanks for the reply. I meant the one titled “Thermal” (without 2) and there is only one module.

Anyway, I solved my initial problem - it was related to not setting up the ext_i2c correctly. I also used a mix of M5Unified and M5AtomS3 libraries because out of the box the FastLED that is referred to from M5Unified does not compile and fails with a static pin value check at compile time. I solved all this (and learned a lot).

Now the only problem I have is: how do I connect the two small M5 modules with a male to male adapter. The grove cable works fine for me but I want a zero length grove male 2 male connection so I can print a 3D case and put both modules into it.

I should have said I am concerned about the form factor, since the 18650C holds the M5Stick INSIDE its case.

I checked the size of each M5Stick product and they are the same size i.e.
Product Size 48.225.513.7mm.

So the answer should be yes.

Thanks anyhow, ajb2k3.

@ajb2k3 Got it now thanks. I was trying to use the UIFlow 1.X example.

Hello @pos3tap

hmm, works for me in UIFlow2. Please see example in Project Zone: M5Dial_RFID_Touch_Test_UIFlow2.1.5

Thanks

@stanislav-drca I use the image Editor G.I.M.P from gimp.org. as to the image formatting. the setting are on the forum somewhere.

@aiconnection I believe its something in relation to your other post here in this forum from days back, this post gives a bit more info on what you are trying to do but still lack of details, its hard to advice without knowing what type of hardware you want to use and how you planning to connect to it really.

for start @GhostOfRain install m5burner, log in to your account, look for m5stickC Plus2 latest firmware, burn it to your device.

Hello @JDEVW

no, there are no stock built-in charging indicators. That said, they can be added. See here.

If you look at the back of your M5Cardputer you'll see that the battery voltage can be monitored via G10.

Thanks
Felix

@lamfan You need to show your code so we can try to see what's happening.

@mgrouch Hi there, the M5Unified library has a calibration routine that works well. See the IMU example in the library, and make sure to read all of the comments carefully.

You press the Atom BtnA (screen) and it will calibrate for 10 seconds, enough to do one axis at a time. You are best to calibrate the accelerometer, gyro and magnetometer separately for best results.

Personally I modified the example so that the calibration starts on press BtnA, and ends on the second press of BtnA. i.e. no 10 second countdown. This way I can take my time and calibrate all 3 axes of each sensor (accl, gyro, or mag) in one continuous movement.

@aitech Dont' throw that sensor away yet.
There is an error in the ENV_Pro demo code:
Line 51 should read Wire.begin();
After changing that it worked fine for me.
The interface address for the sensor is actually defined on line 57.
Pretty impressive sensor.
