Hey @reverbrick @felmue

I am currently encountering the same porblem. Can you explain me where I can find the i2c.readfrom_mem()?

Thank you very much!

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

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....

@kuriko
The error occurs in version V2.1.9 and V2.1.8. Version V2.1.7 works.

@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?

@drdrewusaf @TiukuP @falbriard @gbelfor @heyheyyt @Rango @RBOUMAN58
already fixed, thanks for patience

Run following command in Terminal:

xattr -c /Applications/M5Burner.app

This will remove the quarantine flags from the app.

this issue was fixed in 2.1.8-hotfix

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:
