The TWELITE wireless microcontroller is written with App\_Twelite (standard app) or App\_Wings, and the serial message from the communication partner is displayed before it is used.

The communication partner is App\_Twelite (standard app), and when it receives a standard app button or analog input status message (0x81 message), its contents are interpreted and displayed by mwm5's parser library.
