Thank you for answering.
I used the firmware when I purchased M5GO.
By using the Japanese manual that you taught, I was able to check the operation in UIFlow.
I did not know that M5GO WebIDE can not be used.
I will use UIFlow or M5Cloud in the future.
I think it would make sense to add forum categories for MicroPython topics and a separate category for arduino topics. Also there needs to be a release notes page for uiflow that indicates the new changes whenever an update occurs for this tool. It would be helpful to see documentation on the changes so users can help to more easily contribute.
