I have the exact problem: Chrome 107.0.5304.110 on Fedora 35. All buttons in the UI (label, button, line, etc) are nonfunctional as well as the "load", "save" etc buttons. UIFlow is completely unusable with Chrome. I can reproduce this in Konqueror also. The buttons seem to work in Firefox though.

This sensor is surprisingly difficult to use but I still learned a lot. As suggested, I took a look at the raw data from the sensor using an M5Stack Arduino program. Although you can see the pulse data, it is very unstable, noisy and has a varying offset. Here is a very good description of what it takes to make the MAX30100 work. https://morf.lv/implementing-pulse-oximeter-using-max30100 In addition to what the article says, the two Heart sensors I have behave differently and would require individual calibrations.

Hello @roadfox in case you are still looking for a suitable NB-IoT SIM card. I recently got one from Miotiq which works fine for me. See here for more detail. Thanks Felix

@bladehunt0 I know that this is not an answer to your problem...I use a Core Basic to control the HVAC in my home office and the top reading is: Room Temp 24.3 Fortunately the % sign is supported for Humidity!!! Here is an experiment! M5.Lcd.setCursor(272, 98); M5.Lcd.setFreeFont(FS9); M5.Lcd.print("o"); worked surprisingly well. The "98" is 16 pixels higher than the reading. https://imgur.com/qMvmT7s

@tinkerer I made a quick reader nothing special and this is on a Basic Core unit quick video showing it working https://youtu.be/qvtr6Vy-HwY The Tags I use are these ones make sure the port is correct otherwise the bytes out of range error pops up from m5stack import * from m5ui import * from uiflow import * import unit setScreenColor(0x222222) uhf_rfid_0 = unit.get(unit.UHF_RFID, unit.PORTA) uhf_rfid_0.set_region(uhf_rfid_0.REGIN_US) uhf_rfid_0.automatic_freq_hopping(0xFF) uhf_rfid_0.set_channel_freq(924.25) epc_bool = 0 uhf_rfid_0.set_select_mode(0x01) label0 = M5TextBox(128, 59, "Tag #", lcd.FONT_Default, 0xFFFFFF, rotate=0) label1 = M5TextBox(22, 106, "waiting ...

@pengyuyan The m5stack-basic esp32 is mainly used for the Internet of Things. The robotic arm needs a bridge to connect to the computer, where the m5stack-basic esp32 development board is used, which also powers the arm. We have set up some microPython in the m5 to facilitate using some functions.

Glad to hear it worked for you too!

@holofloh good call, but if the // are removed then the ledc commands are “before” the open curly brackets { of the next line, so I am still confused!

was able to get this resolved be removing/re-installing the drivers a bunch of times. Appreciate the assist!

Thanks #teastain that works! I simply changed ADXL345 accel(ADXL345_STD) to ADXL345 accel(ADXL345_ALT) in example code ReadXYZ.ino. Thanks again.

I am a little ashamed, it was not a driver problem. In M5burner I didn't give the information about the wifi which prevented me to burn my M5Stick. It's confusing, the error message is about a port problem. Thank you all for your answers

Hello @kilnageer you are welcome. Thank you for reporting back. I am happy to read that it worked for you. Same to you! Thanks Felix

yes!!

It's built like this image. My solar panel is a 5 volt 60mA panel. The battery is a 500mA lipo battery. The output on the right (in the image the dc-dc step up, my timercam is connected) in the image connects to the onboard connector of the Timercam. I've used the original plastic shipping case to construct a waterproof case for the components.

Hello @swiminthesky Re: Edit2: you'll need to press and hold BtnA to record something. The recording starts after the vibration and ends when BtnA is released (or after a certain amount of data has been recorded). if (data_offset == 1024 * 100 || M5.Touch.ispressed() != true) break; Thanks Felix

Thanks for the hint. That code won't compile: 'MLX90640_BadPixelsCorrection' was not declared in this scope. If you comment out the reference to MLX90640_BadPixelsCorrection it compiles and works OK. In the meantime I got a UIFlow version working more or less. Download from https://github.com/wsanders/WSThermalCore2Cam/blob/main/thermtest1.m5f. It's pretty crude but it autoranges OK if the temperature differences aren't too bad. Using ASCII art pixels because it's faster than drawing two rectangle (you STILL can't draw a borderless rectangle in UIFlow!) Sorry - I deleted my previous post accidentally. It was full of errors anyway.
