Description

This is a kind of USB Serial Terminal application that contains some graphics. Also there is a serial monitor in it.

You can use this app with Arduino or another microcontroller for your robotics projects and etc.

This application has feature for communication with Arduinos and other USB serial hardware on Android, using the Android USB Host Mode (OTG).

WARNING!! For now, only these communication parameters are valid:
*** Baud: 115200, Data: 8bits, Stop bits: 1bit, PARITY: NONE ***

You can see real time 3 graphics of some values.
This values must be sent in a sequence.

This sequence must be like that: Evalue1,value2,value3...\n

For example: "E256,-321,982\n" or "E902,1235,10,23,-325,-1240,90\n" etc.

Comments on USB Terminal/Graphics for Android

★★★★☆ Ian Hall · Feb 24, 2022

For a freebie it works nicely for testing a remote project without taking a laptop along. It took me a while to realize it specifically needs the letter "E" in the first serial.print. Would be good to be able to look at a different app and come back without losing all data. If you could name each data stream on a chart key it would help. I've had it charting 2 set points, 2 measured values and 2 outputs at the same time.

Doesn't work on nothing phone 3A pro, can't seem to detect any Bluetooth connections.
