i came into possession of an arduino with a usb host shield () and configured it to read the foot pedal. the developer wasn't able to implement a solution to this issue, referencing system-level reasons that went over my head. Originally, i was using this 3 button footswitch in REAPER via Bidule's HID-to-MIDI converter, but this sucks because it lost its association every time a different USB device was plugged in.

it sends messages that are used for dictation software, but not keyboard characters or anything else that i can use as a joystick/input for REAPER - hence the mystery EDIT - i shouldn't say 'mystery HID,' because it's an infinity in-usb-2 footpedal. SafeString::Output.print(sf2hex) SafeString::Output.Howdy, diy friends. Serial.write((uint8_t)hexValue) // send as unsigned 8 bits <<<<<< this is the real data when not TESTING PrintBinToDebug(hexValue) SafeString::Output.print(' ') // for testing SfTest.substring(sf2hex, startIdx, endIdx) Ignoring last char!!')) ĬSF(sf2hex, 2) // as SafeString to hold two hex chars

SafeString::Output.println(F(' testOutput does not have even numbers of chars. wrap the testOutput in a SafeString from processingĬSFA(sfTest, testOutput) // or createSafeStringFromArray(sfTest,testOutput) cSFA is just shorthand SafeString::setOutput(Serial) // commenting this out removes error msgs and debug printing Here is the sketch // download SafeString library from Arduino library manager TestOutput does not have even numbers of chars. With TESTING not comment out it converts the hex string to bytes and prints the binary version. As I understand it, you have this 'test' string in HEX to send.Ī) convert each pair of the hex chars to a single byte and thenī) write( ) that byte to the Serial connection
