@cloudmonkey it’s on my work list for the documents

@jondaaa refer to examples in Project Zone

Well, I think I've made a beginner's mistake. I didn't restart PaperS3. After flashing it, I pressed the reset/boot/... button and it displayed the UiFlow page on PaperS3. Thanks for your help Felix

To use HTTP GET in uiflow2 for fetching JSON, use the "HTTP Request" block. Set the method to "GET" and provide the URL of the API. Then, process the response with a JSON block to parse the data.

Hello @digiajay ok, understood. Well, you cannot set a different EOL character and therefore you cannot use UART block read line. However you can use block count of available and read 1 bytes etc. to read chars sent from your device. As long as the char received is not your EOL char, append them into a buffer. And when you receive your EOL char do something with the chars accumulated in the buffer, then clear the buffer and start over. Thanks Felix

@ajb2k3 @kuriko I just tested it again but with the firmware 2.1.0. It works on pin 1, 2 and 10. I think there is a bug in the firmware 2.1.9....

@FlappyCat You accidentally entered M5 website hosted by Switch Science Use this: https://m5burner-cdn.m5stack.com/app/M5Burner-v3-beta-win-x64.zip

@echiz I think the support of LVGL has been removed in the newest version of UiFlow2 Maybe change it to a elder version will have chance?

@Bzh2ant2 Did you erase first? Did you hold the boot mode button before erasing and burning firmware?

@mb this issue was fixed in 2.1.8-hotfix

@mb If the program runs normally, I don't think this should be a problem

@Rango known issue, fixing

@ajb2k3 Using M5Burner v3.0.0 on MacOS v14.7 on MacBook M3.

@mb check VolosR YT examples to his UI approach

@kuriko Thank you

@sternj Well, the Arduino IDE ver2 IDE is very good. Just type in C, C++ and download (it compiles automatically.) This is NOT your grandad's Arduino IDE ver 1 !!! Here is a sample program to test serial: bool ticktock; //declare ticktock as a boolean flag void setup() { //runs once on start up Serial.begin(115200); //open the serial port for USB cable delay(500); } void loop() { //runs in circles! ticktock = !ticktock; //every pass through reverse the flag if (ticktock) { //test current value of the ticktock flag Serial.println("tick"); } else { //prints one or the other to the USB port Serial.println("tock"); } delay(1000); //wait for a second and run again! }

@kuriko any pointers on how to do that? There's nothing about it in the docs: https://uiflow-micropython.readthedocs.io/en/develop/software/requests2.html

@kuriko Great! Thanks, can't wait to see it!

@kuriko Thank you for your reply! It seems I might be able to resolve this by reviewing the past file samples. There are still many aspects, like the calibration movements, that I don’t fully understand yet, but I’ll keep working on it and exploring various options. (This is a machine translation, but I hope it conveys my message well!)

Hi @kochikame Would you able to show your code?
