I’ve ensured that the baud rate settings of my Arduino, the Hairless MIDI Serial Bridge, and CoolTerm are all set to transmit and receive at the same rate (in this example, 57600 baud, 8 data bits, no parity, and 1 stop bit.)

In spite of its simplicity, when running this code on my Mega, CoolTerm still displays delayed serial transmissions in irregular bursts. TestVal = value //pure CC value (0-127) for testing purposes
If (number = 71) //rotary encoder 'B1' on axiom controller Void ControlViaCC (byte channel, byte number, byte value) Void HandleControlChange (byte channel, byte number, byte value) MIDI Controller MIDI output -> Hairless MIDI/Serial Bridge -> Arduino Mega -> CoolTermįor testing purposes, I created a much simpler sketch to rule out any other possible issues in my code: #include This is my serial data flow configuration: I originally noticed this when attempting to debug a large sketch wherein I’m configuring my Arduino to receive MIDI data being transmitted from a MIDI controller and use the MIDI signals to control a variety of LEDs, servos, and a stepper motor. CoolTerm seems to be displaying serial data from the Arduino Mega in short bursts every 5 - 15 seconds even though it should be displaying a continuous stream of values every second.

(FWIW, I’m running on a Mac - OS 10.9.1).
Note that these procedures only work if you don't have hardware flow control active.I’m attempting to use CoolTerm as a serial monitor for debugging purposes when working with an Arduino Mega (2560), but have noticed that CoolTerm is not accurately receiving the serial data being transmitted to it from my Mega.

Windows users can refer here for a similar solution $ sudo interceptty -s 'ispeed 9600 ospeed 9600' /dev/pts/2 /dev/ttyUSB0įor this to work reliably, I have to run first the two instances of interceptty and then open the USB ports (in my case with minicom). This is an example of what I capture writing on port 0 and port 1 with minicom: > 0x48 (H)įor your particular case, you only have one port on your computer, so you can create the virtual port pair with just one link: $ sudo socat -d -d pty,link=/dev/ttyUSB0,raw,echo=0 pty,raw,echo=0Īnd run two sessions of interceptty: $ sudo interceptty -s 'ispeed 9600 ospeed 9600' /dev/pts/1 /dev/ttyUSB0 I will now see all data traveling on the bus. This is the output I get (note the names of the virtual devices created): 3 08:23:32 socat N PTY is /dev/pts/1ģ 08:23:32 socat N PTY is /dev/pts/2ģ 08:23:32 socat N starting data transfer loop with FDs and Īnd then I can run interceptty on a third terminal: $sudo interceptty -s 'ispeed 9600 ospeed 9600' /dev/pts/2 /dev/ttyUSB1 Now, if I want to snif on this link I can do the following: first I create a couple of virtual serial ports and link them to my real ports: $ sudo socat -d -d pty,link=/dev/ttyUSB0,raw,echo=0 pty,link=/dev/ttyUSB1,raw,echo=0 I can open two terminals and send text from port 0 to port 1 or viceversa with minicom or any other terminal utility. I have linked them together with wires: RX on port 0 goes to TX on port 1, port 0 TX goes to port 1 RX.
In my setup, I have two real (well, they are actually USB-to-serial adaptors) serial ports on /dev/ttyUSB0 and /dev/ttyUSB1.
