  1. Hi everyone, TLDNR: How do I set up MIDI descriptors for MIDI over USB so that I can get my PC to recognize my F5510 as a class-compliant MIDI device, either using the TI USB Dev package, api, and descriptor tool, or manually? I'm working on my first MSP430 project and hoping to get some help setting up the USB interface in CCS. I'm working with an MSP430F5510 on a custom board and trying to set it up so that it's recognized as a class-compliant midi device on the PC - then I will send midi messages to the PC to control music programs, etc. I'm stuck on where to start for configuring the U
  2. I decided to have a crack at building some drum pads, because the keyboard that I'd acquired for the kids to learn piano on had a midi input, and somewhat acceptable drum sounds to boot. After several months of sitting around half-completed under a cupboard, I decided to pull it out over the easter weekend and actually make it work. In words, here's what I did. Six drum pads, made of a square of hardboard with 5mm closed-cell foam glued to the top and standing on 15mm foam pads. Each pad has a piezo electric transducer underneath, attached using hot glue. These six piezos are each hook
  3. Hey forum! I always wanted to make a synthesizer , so i chose the msp430 launchpad, because it's one of the most inappropriate chip i can use for it :grin: When i started to make it i didn't have real goal, i just wanted to make a sound, so this project is kind if all over the place but i have learned a lot doing it so it was totally worth it. The DAC used is a TI TLC5615, it's not the best choice, but i only had this in my parts bin. Probably any other SPI DAC could be used with minimal modification, or even PWM. (I don't sound good with PWM IMO.) The TLC5615 needs 5 volts, but
  4. Hello, I tried out basic functionality with the arduino MIDI library 4.1 on TIVA Launchpad TM4C123G (all others should work also) Download Link: https://github.com/FortySevenEffects/arduino_midi_library/ The only thing to do is to setup the serial interface, you can simply do that with insert following line into midi_Settings.h: #define MIDI_DEFAULT_SERIAL_PORT Serial1 "Serial1" defines PC_4 = RX(1) input on tiva, PC_5 = TX(1) output on tiva, so you should choose every serial port you want (untested). my patched midi_Settings.h is included as attachement I´ve tested succe
  5. My first Tiva project, MIDI -> DMX bridge (this is the 3rd version, the other 2 were MSP430F5xxx based.) It has 6 universes, 512 channels each, and includes PoE. Initially, the software was written (with the exception of MIDI and mapping/sequencing part) entirely using TivaWare, and then most critical parts were optimized.
  6. Hi there. Probably some of you know already the existence of this MIDI boosterpack published on 43oh forums (check the original thread here). This board is a great tool for musicians and/or audio engineers, it features two DIN-5 MIDI connectors (MIDI IN and MIDI OUT) along with two switches and potentiometers. It allows to receive and send MIDI messages through the mcu's UART modules, and the incorporation of the potentiometers help for applications such as arpeggiators, sequencers, harmonizers and everything you can imagine. The original author provides some code examples for MSP
  7. Hi everyone, I'm trying to implement a midi output communication, but there seem to be a problem and I'm not sure if it's with my software or hardware. So here's what I'm getting... I'm trying to do it with a Launchpad rev 1.4 with the MSP430G2231 chip. I connected my launchpad to a midi connector like they told on the Teensy Midi Library page http://www.pjrc.com/teensy/td_libs_MIDI.html So translated to the launchpad: P1_1 (TX pin) to midi Pin 5 (tried with and without a 220 ohms resistor) GND to midi Pin 2 VCC to midi Pin 4 with a 220 ohms resistor For the VCC
  8. Found a french blog with a launchpad (and Energia) flavor to it. A couple of different write ups, from simple button tutorials to adc and lcd, as well as motor control. Google Translate works well enough for english.
