UIFlow 1.5.2

jpilarski

The problem I am having looks to be whenever I add certain blocks, for example the loop block, it changes the position of the blynk.init() code and puts it several lines lower in the python code and thus out of order. Even when the blynk.init() was previously working, as soon as I add certain blocks, it puts the blynk.init() several lines lower in the code and this is preventing blynk from working and requires the user the manually cut and paste the blynk.init() line to put it in the correct position. Maybe I'm wrong about how I am using the the blynk blocks. It would be great to see a few screen shots showing how other users are implementing the blocks. thanks

@jpilarski could share you program ? I have test it. event i add a loop block. the blynk init seem still in the correct position. so if you could take a screenshot show me the program, it will very helpful for us to solve this problem.

Here is a quick example

This code doesn't ever connect to blynk. Here is the code it generates:

from m5stack import *
from m5ui import *
from uiflow import *
from ble import blynk

setScreenColor(0x222222)




label0 = M5TextBox(52, 10, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
label1 = M5TextBox(46, 49, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
circle0 = M5Circle(141, 122, 15, 0xFFFFFF, 0xFFFFFF)

val = None
message = None



blynk.init('fire', 'xxx', blynk.BLE)
while True:
  circle0.setSize(val)
  wait_ms(2)


@blynk.handle_event('connected')
def blynk_write():
  global val, message
  rgb.setColorAll(0xff0000)

  pass



@blynk.handle_event('write v2')
def blynk_write(*args):
  global val, message
  val, message = args[0], args[1]
  label0.setText(str(val))
  label1.setText(str(message))

  pass

Here is the manually adjusted code that connects with blynk.

from m5stack import *
from m5ui import *
from uiflow import *
from ble import blynk
blynk.init('fire', 'xxx', blynk.BLE)
setScreenColor(0x222222)


label0 = M5TextBox(52, 10, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
label1 = M5TextBox(46, 49, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
circle0 = M5Circle(141, 122, 15, 0xFFFFFF, 0xFFFFFF)

val = None
message = None



@blynk.handle_event('connected')
def blynk_write():
  global val, message
  rgb.setColorAll(0xff0000)

  pass



@blynk.handle_event('write v2')
def blynk_write(*args):
  global val, message
  val, message = args[0], args[1]
  label0.setText(str(val))
  label1.setText(str(message))

  pass

while True:
  circle0.setSize(val)
  wait_ms(2)

In the example above when the message variable is shown using label1.setText(str(message)) it shows the following ['255']. What is the most effective way in micropython to remove the [] and ' ' and convert message variable to an integer. I am using

which outputs this

@blynk.handle_event('write v2')
def blynk_write(*args):
  global val, message
  val, message = args[0], args[1]
  message = str(message.replace("'", '').replace(']', '').replace('[', ''))
  label0.setText(str(val))
  label1.setText(str(message))
  circle0.setSize(int(message))

  pass

but should generate this

@blynk.handle_event('write v2')
def blynk_write(*args):
  global val, message
  val, message = args[0], args[1]
  message = str(message).replace("'", '').replace(']', '').replace('[', '')
  label0.setText(str(val))
  label1.setText(str(message))
  circle0.setSize(int(message))

  pass

@jpilarski Some time ago I did custom blocks for blynk. They use rest api requests for communication, so they are not as advanced as those from uiflow. maybe these will work for you. I tested them on m5stickC and works.

https://github.com/stonatm/UiFlow-custom-blocks/blob/master/blynk/README.md

jpilarski

@robalstona @m5stack Thanks for that suggestion. I'll try the blocks you developed out on StickC. The new ble blynk blocks work it"s just they require a little tinkering with the micropython code to get them connected. At least that is my experience of using them. I am still very happy to see them included in the latest beta version of uiflow. Also I look forward to seeing a screen_shot showing all the blocks operating together in a single setup because I might be setting them up in a way that introduces the minor issues I've come across.

m5stack

@jpilarski ok, the problem is clear. thank you feedback, we will fix this bug ASAP.

jpilarski

@m5stack
Very cool. Thanks and it's really great to see bluetooth in micropython and uiflow. At one time you mentioned the micropython firmwares would be open source and made available on github, I know you have a uiflow micropython repo https://github.com/m5stack/UIFlow-Code but it doesn't always get updated with new releases, it would be great to see the repo get updated and have branches for each major release. I think so much great development can happen if the code is made available.

m5stack

@jpilarski You can talk about which lib your users want to open source.

Thrasher

@m5stack
Can we have document with something like:
UIFlow lib
--API
--Methods
--Method example / construction
The way Arduino document its built-in libraries or similar to this?
Thank you

m5stack

@thrasher

we had open source part UIFlow lib code. in this github :https://github.com/m5stack/UIFlow-Code

Taking into account some lib data security issues, we will not open source all libs for the time being, so you can talk about which libs users want, we will consider if open source these lib.

Thrasher

@m5stack
I don't need source code.
I'd like documentation on API usage
E.g. LCD
-Lcd.print(text, posx, posy, size) - prints a text string
Etc.
Im not looking for any source code
Thanks
Here's example from arduino:
https://www.arduino.cc/en/reference/libraries

And detailed info on functions:
https://www.arduino.cc/en/Reference/SD

No source code there but all functions detailed and explained how to use
Because blockly, Im sorry, is just lame

Sorry, I have been busy and suffering depression which resulted in my book getting neglected.

@ajb2k3 Take care boss. Slow down and enjoy the earl grey.

Also: don't.do.anything.stupid. :D
