Hello,
try an execute block, look at my code below.

First i defined the two variables "is_running" and "counter".
In UIFlow i defined pin0 with GPIO26 as input with pull down resistor.!
Then i defined the event_interrupt(pin) - procedure. I use it for counting impulses at the GPIO26, therefore it is necessary to declare the variables as globals.

Every second i read in the main loop the value of the counter variable and reset the is_running variable.

def event_interrupt(pin):
global is_running, counter
is_running = True
counter += 1

pin0.irq(trigger=machine.Pin.IRQ_RISING, handler=event_interrupt)

Many thanks to the team for the implementation of:

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

in UIFlow version 1.6, great job!

Now please check if it's possible to add the gps-date.

And if you try to use the gps-module with the M5GO/FIRE battery module it won't work Therefore you have to remove the M5GO/FIRE battery module to get gps data form the gps-module. But the gps-unit works well.
I think there may be a conflict with the uart of the gps-module and the M5GO/FIRE battery module?

Hi,
wiht the Execute code of the advanced section you can enter python code, because if you take the replace block in the text section the '\n' will be changed by UIFlow into '\n'.
See my UIFlow-Example:

... and the following is the python code of my example:

from m5stack import *
from m5ui import *
from uiflow import *

setScreenColor(0x222222)

label0 = M5TextBox(0, 30, "Text", lcd.FONT_DejaVu18,0xFFFFFF, rotate=0)
label1 = M5TextBox(0, 120, "Text", lcd.FONT_DejaVu18,0xFFFFFF, rotate=0)
rectangle0 = M5Rect(0, 100, 320, 5, 0xFFFFFF, 0xFFFFFF)

str_original = None
str_parse = None

str_original = ''
str_parse = ''
str_original = 'TEXT1 TEXT2\n\nTEXT3'
label0.setText(str(str_original))
str_parse = str_original.replace(' ', '\n')
str_parse = str_parse.replace('\n\n', '\n')
label1.setText(str(str_parse))

@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

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.
