spirilis 1,265 Posted June 4, 2013 Share Posted June 4, 2013 grabbed one! woot Quote Link to post Share on other sites
mymaestro 1 Posted August 19, 2013 Share Posted August 19, 2013 I got one in the Tindie store (I see they are all sold out now) and ported my Arduino code over using Energia. The MIDI library for Arduino, version 3.2, http://arduinomidilib.sourceforge.net/ works with no changes! I have a Rockband controller keyboard with a MIDI out, but it only transmits on channel 1. So I wrote the code to have the MSP430+MIDI breakout translate to whatever channel I want, by pressing S2 for channel UP and S1 for channel DOWN. The pots seem to be pretty noisy but I use one of them as a volume knob anyway. RobG 1 Quote Link to post Share on other sites
L293D 11 Posted September 19, 2013 Share Posted September 19, 2013 Does the kit in the 43oh store come with the DAC? I don't see it in the picture (and in the build thread it says it is optional). Quote Link to post Share on other sites
RobG 1,892 Posted September 19, 2013 Author Share Posted September 19, 2013 The current kit doesn't have DAC option (I should have some PCBs with DAC option if you are interested.) Quote Link to post Share on other sites
gonya707 2 Posted October 7, 2013 Share Posted October 7, 2013 I just opened a thread on Stelarisiti for this boosterpack. Check it out here. Thanks again Rob for this wonderful boostepack RobG and bluehash 2 Quote Link to post Share on other sites
ABeardedSwede 0 Posted December 15, 2014 Share Posted December 15, 2014 RobG,We are a group of electrical engineering students experimenting with MIDI communication involving the MSP430G2553. We hope to be able to make a simple MIDI Controller using your MIDI Booster Pack. Currently, we are attempting to understand the UART TX stage of this project. We're compiling our code in TI's CCS software. As of now, we have our ADC10 code working and are able to read ADC values from a potentiometer, but we are confused on how to transmit a MIDI signal via UART. To be specific, we think we know how to initialize the UART registers for proper communication, but we're stuck on how to exactly move our ADC10 signal with the MIDI protocol through UART to the MIDI Shield.We were hoping that you could either point us in the correct direction to build code or provide an example skeleton code for a simple MIDI controller.Any help would be greatly appreciated, thank you for your time. -Nick, Nic, and Chris Quote Link to post Share on other sites
RobG 1,892 Posted December 15, 2014 Author Share Posted December 15, 2014 @@ABeardedSwede, here's a sample code (this is what I used for Tindie video.) This code has some extra things that you don't rally need. To send MIDI, all you need is a circular buffer to which you add necessary number of bytes for each MIDI event. midi_arp_with_adc.cmidi_arpeggiator.hmidi_constants.h ABeardedSwede 1 Quote Link to post Share on other sites
PowerShower 0 Posted March 29, 2016 Share Posted March 29, 2016 This seems to be an older thread but I'm stoked to find it! Is there any way to still buy the booster pack or do I need to make my own? The tindie store says there's a waiting list but this project is due at the end of the semester. Quote Link to post Share on other sites
roadrunner84 466 Posted March 30, 2016 Share Posted March 30, 2016 If you are doing electronics studies, you'd better make your own, the schematic (which is really really simple) is linked to from the tindie store. Also note that the boosterpack sports both midi in and midi out, if you need only one of those, you can skip half the schematic. Quote Link to post Share on other sites
Clavier 34 Posted March 30, 2016 Share Posted March 30, 2016 the schematic is linked to from the tindie store. And it links to this thread! And the schematic is capable of improvement: the output connector's pin 2 must be grounded; the unused inverters' inputs must not float; the optocoupler needs a resistor of about 10 k? between pins 5 and 7; and it needs a decoupling capacitor between pins 5 and 8. zeke 1 Quote Link to post Share on other sites

Sorry I missed your post (I was on vacation.) I will have new version available soon, but I should have one kit left if you need it right away. Quote Link to post Share on other sites
