@m5stack in the Arduino TinyGPS ++ library GPS speed is available, but it would be great to be able to use it with UIFlow.

Is there any mircopython gps-library (or commands) available which can be accessed with execute blocks?

When using the gps-unit how can i get the actual speed, or how can i calculate it from longitude and latitude?

In UI Flow only the following values are available:

• time
• latitude
• longitude
• satellite num
• positioning quality

By the way, when will the gps module implemented in UIFlow?

I had similar problems, here you find my way for solving these

I made a hour counter using UI-Flow. When i test it using the run button of UI-Flow it works fine, but when i try downloading the program to the m5stack it also freezes.

After adding more program code, the testing also fails because the py-code where re-sorted by UI-Flow and some procedures where located at the end and are not reachable for the main loop. After manually sorting the procedures in a correct order the program runs fine again but downloading is again not possible.

The cause of this behaviour is that UI-Flow stores the complete blockly-file (.m5f-file-type) in addition to the py-code to the m5stack. Therefore i used vs-code to transfer the py-code directly to the m5stack without the blockly-file and the program runs.

My conclusions for big programs:

1. they will be resorted by UI-Flow in a unexpected manner
2. they can't download with UI-Flow, i belive the cause is located in a memory limitation
3. but they can be transferred by using vs-code, to do this see also the m5stack video: https://www.youtube.com/watch?v=Y9pOWgsNgKk

@cepics said in All my M5Stack/Stick sketch doesn't compile anymore:

Multiple libraries were found for "SPI.h"
Used: /Users/ce/Documents/Arduino/hardware/espressif/esp32/libraries/SPI

You have installed multiple libraries

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Use the option "Show verbose output during compilation", as shown in the compiler message, to get more information about the problem.

Hi @zorfox, during first start up of my m5stack i went also in problems with m5burner.

On a second laptop the m5burner runs well.

Then back to the first laptop it runs, but i took an other usb-port.

Test other usb-ports at your pc, may be that this is the problems solution.

Hi @lukasmaximus thank you for the micropython code.

This is my test program for writing and reading data to/from SD card:

Is there a possebility adding files at the posting? then i can add the Blockly-file here.

And last but not least a short whish list for improvements at UiFlow:

• Early implementation of the actual UiFlow-Beta-version to the UiFlow-PC-Version
• Adding remarks in a easy way, i took thererfore the execute block using a #
• Blocks for handling SD cards (reading, writing, appending data)
• Adding files in postings at the M5Stack community

Hi everyone!
Using UiFlow V1.3.5-Beta, i'm buliding a hour counter for my boat engine.

The new timer blocks are great and very helpful, many thanks to the team.

To store and restore the cumulated seconds i need code for the UiFlow-execute block for reading and writing the sd-card:

• Is there anyone who can help me?
• Or are SD-card blocks foreseeen for the next beta version?

For a first preview of the hour counter here you can see the display content:

... translation of the german text:
Title:

• Betriebsstunden = Operating Hours

Labels:

• Stunden = Hours
• Tag = Day
• Batterie = Battery

The Button Labeles are in english
