Hello @xbr11332003 have you tried to send the data with trailing CR LF? E.g. uart1.write('hallo\r\n')? Works for me. Thanks Felix

Hello @robski I don't have an ENV II but with an ENV I, I get the same error 'device not found' as reported here. As far as I can tell the issue seems to be the underlying I2C code. Thanks Felix

Seems to be down for me at the moment. Thanks, Matthew

Hello @mascaos you probably know this already - often for things where no native block is available you can use the generic Execute mpy code block as shown in the example in the Project Zone: M5Dial_RFID_as_hex_string_UIFlow2.0.7 Thanks Felix

Worked it out. The Stick was showing V1.13.4, which was the firmware version for UIFlow 1. I had previously flashed that onto the stick. When I was burning UIFlow 2, it didn't erase or overwrite the V1 firmware. I forced an erase by going to Burn / Erase. The stick is now showing the V2 firmware and I am able to flash new programs to it.

@ajb2k3 I would have chosen Monty Arduino. -cheers

@felmue Thank you for the prompt response, I will try it today

I have the same problem with UIFlow2 and Core Basic.

@sergvir looks like it’s a used and returned unit

You have missed a step there, you must Erase the existing firmware before burning new firmware.

Hello @dlhawley are you positive you have burnt the latest UIFlow2 firmware (e.g. v2.0.5) onto your M5Stick Plus (not 2)? I see the following line for my M5Stick Plus (not 2): MicroPython v1.22.0-dirty on 2024-05-11; M5Stack StickC PLUS with ESP32 Thanks Felix

I can't upload image file. According to the response message, "Failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.impl.IOFileUploadException: Processing of multipart/form-data request failed. No space left on device". Perhaps the server's temporary upload area has been exhausted? I think it is the same reason why the project cannot be saved.

Here is a workaround for UIFLow2.0: import M5 import hardware import time # UIFlow2.0 workaround for M5.Power.timerSleep() not working properly # on SOME CoreINK devices. On these decvices the board-power is not # proberly turned off. However, the M5.Power.powerOff() does work # for these devices, i.e. turning board-power properly off M5.begin() #init i2c bus with pins connected to the RTC i2c0 = hardware.I2C(0, scl=hardware.Pin(22), sda=hardware.Pin(21), freq=400000) ##### Put your code here. time.sleep(3) ##### code substitution the timerSleep() function # Set registers of the RTC. ref datasheet for BM8563 RTC for further info # reg 0x00 always 00h # reg 0x01 bit 2-7: always 0, bit 0: enable/disable timer int # 0x01 = timer enabled reg00_01 = bytearray([0x00, 0x01]) # reg 0x0D always 00h - clock out disabled # reg 0x0E bit 7: endable/disable timer, bit 0-1 timer resolution # 10=sec 11 = min # 0x82 = int enabled and seconds resolution # reg 0x0F timer value 0-255 # 0x14 = 20d = 20 sec. if reg 0x0E = 0x83 then 20 min reg0D_0F = bytearray([0x00, 0x82, 0x14]) # i2c device address of RTC is 0x51 # Write to register address 0x00-0x01 i2c0.writeto_mem(0x51,0x00, reg00_01) # Write to register adsress 0x0D-0x0F i2c0.writeto_mem(0x51,0x0D, reg0D_0F) M5.Power.powerOff() ##### end of code substitution the timerSleep() function

Make sure you erase and burn the correct firmware for the controller, UIFlow and uiflow2 are not the same

Statically you can center a label in the UI-editor. Dynamically not so easy as far as I can see, because there is no way to get the width and height of a particular string. If your program is only outputting a known set of strings you could make a small table (dictionary or similar) with the "center coordinates" for each string....
