Hairless Midi isn't able to read data #32

Closed mr-dgidgi closed 6 years ago

mr-dgidgi commented 6 years ago

Description of the problem or question

When I use Hairless MIDI Serial to test my circuit it is not able to read midi data and I have strange messages like bellow : 


 +233.822 - Serial In: System Message #14
 +233.826 - Serial In: System Message #14
 +233.899 - Warning: got a status byte when we were expecting 3 more data bytes, sending possibly incomplete MIDI message 0xff
 +233.899 - Serial Says: 
 +233.899 - Warning: got a status byte when we were expecting 3 more data bytes, sending possibly incomplete MIDI message 0xff

This only append with Hairless. When I disable HairlessMIDI_Interface and activate USBDebugMIDI_Interface I'm able to see correct midi data.

I'm doing it to repare a Gemini G4v controller with an arduino, my code is huge but I also tried with only one potentiometer and the issue is the same.

Steps to reproduce the problem

Connect few potentiometers to a mux use HairlessMIDI_Interface. Hairless midi serial is set to 9600baud

Hardware

Arduino board: ? Arduino MEGA 2560

Software versions:

MIDI Controller library: ? 3.0.1

Steps taken to try to diagnose or solve the problem

Work properly with midi debug and serial terminal.

The goal of your project and aditional information

I'm fixing a Gemini G4v which has been connected to 12v instead of 5v. Microcontrollers are dead but button, potentiometer, mux, shift register and led are still alive. The goal is to be able to read the data from every pot/buttons of this controller and send the correct midi data to the computer.

The mux configuration is strange because some mux data output pin are connected to other mux data input in order to use less analog pin on the original configuration.

The default Hairless baud rate is 115200 symbols/second.

(You could change it in the settings, but I recommend just changing it in Hairless, as I think it is the default.) https://github.com/tttapa/MIDI_controller/blob/90b8796f8365faf28bcfa15eab8f70336d9381d6/src/Settings/Settings.h#L10

tttapa commented 6 years ago

Note that HairlessMIDI_Interface is just a wrapper for USBSerialMIDI_Interface:

https://github.com/tttapa/MIDI_controller/blob/90b8796f8365faf28bcfa15eab8f70336d9381d6/src/MIDI_Interfaces/SerialMIDI_Interface.h#L89-L94

So if you want, you can just use USBSerialMIDI_Interface with any baud rate you wish, without having to dive into the settings.

Thanks for your quick feedback. I tried 9600 to 38400 baud but as only 9600baud was not crashing Hairless I thought it was the good baud rate. I tried 115200 and it work perfectly. Thx for the information about USBSerialMIDI_Interface.
