  Hello, meanwhile it is possible to use the block "analog read pin (34)" from the blockpack "Easy I/O". So I was able to bild the probram from user M5DOCS just with UIFLOW. Unfortunally it just shows Numbers between 450 and 600 or so. And it dows not react to any sounds. This is the python code of the blockly program: ===== from m5stack import * from m5ui import * from uiflow import * from easyIO import * setScreenColor(0x222222) label0 = M5TextBox(122, 84, "Text", lcd.FONT_DejaVu24,0xFFFFFF, rotate=0) while True: label0.setText(str(analogRead(34))) wait_ms(100) wait_ms(2) What did I do wrong?

  here you have the library to support ds18b20. You would have to copy these files to your device and from UiFlow call the appropriate micropython commands using the blocks Advanced -> Execute -> Execute code: https://github.com/micropython/micropython/tree/master/drivers/onewire

  Thanks a lot for the information. Was not easy to guess ! To help this tip to be found more easily by other users, I propose some keywords for the search : UIflow : how to remember program and launch it at startup how to make UIFlow program persistent / permanent Thanks again !

  @lukasmaximus Thanks for the tip. I hadn't thought of that. I thought I would have to construct my own block. Peter

  MQTT issues with UIFlow V1.4.5

  @world101 i just manage to have a partial sucess using lastest firmware V1.4.5.1, here my findings a) My Blockly app (which worked last year) contained a loopback test i.e. both a publish and substribe MQTT within the same application (it makes sense just for testing) but that is the very reason i was having problems (app freeze before first statement and "connect fail displayed in red), if i leave the publish statement only then my app does not freeze and after changes on the publish topic including username/feeds/topic (using adafruit server io.adafruit.com and my new credentials) and the Adafruit dashboard correctly display the published value (pressure, emulated with the rotary potenciometer, my ref: Environment_IoT34E_test3_Adafruit_Dashboard_example.png) . b) Despite successful test the behaviour is still UNRELIABLE while booting, still gettin the 'connect fail' message in red after boot ~ every second attempt BUT the application does not freeze anymore and continue working as intended and publishing the topic data as explained above. Again, thank you very much for your "slight' hint about Adafruit difference with cloudmqtt.com.

  @world101 Thanx! After making new topics and setting them to QoS=0, and retain=0, it finally works with many MQTT subscriptions on both M5Stack and M5Stick-C! (1.4.4 and 1.4.5) (PS! Just changing the old topics that had retain back to no retain, did not work, had to make new ones.)

  @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?

  It seems there may be compatibility issues since uiflow firmware version 1.4.0 http://forum.m5stack.com/topic/1388/gps-data try to downgrade your firmware and retry your code

  Thank you, world101, for your quick response. Now Blynk works at my M5STACK. Your Blynk.m5b has five UiFlow blocks for only three virtual functions. But Blynk offers much more features. Has anyone already generated more UiFLOW blocks they can share?

  Thanks so much I totally overlooked the plus sign and I was searching for a block in the map blocks. I’m grateful for you answering my question.

  @world101 said in Speaker beep and Wait: If you want additional testing help, you’ll need to post exactly what your entire flow/program looks like, including connections and Units. Obviously there is something unique in your setup that I don’t have, because it’s working for me. from m5stack import * from m5ui import * from uiflow import * @timerSch.event('timer1') def ttimer1(): speaker.sing(220, 1/16) pass timerSch.run('timer1', 1000, 0x00) --> It works if I download it to the device --> It does not work if I run it from UIFlow

  Sorry, the last few lines should read: CurrentYear = int(RightNow[RTC_YYYY]) CurrentMonth = int(RightNow[RTC_MM]) CurrentDay = int(RightNowRTC_DD]) CurrentHour = int(RightNow[RTC_HH]) CurrentMinute = int(RightNow[RTC_MN]) CurrentSecond = int(RightNow[RTC_SS]) Sorry, this is my first MicroPython program and just learning it.
