this is the repo for a s17 independent study developping hardware with the bela

notes 2/8/17

bbb is acting as a web server 192.168.7.2 editing code on bbb through browser, gets compiled on bbb and then run on bbb bbb has an OSC server and client waiting for something

running osc.js in node on the laptop to talk to bbb

managed to send custom osc message to bela using oscsend

issues getting osc from force to bela

homeworks: look into led metering / layout / order bela / fix all the circuit related issues in http://blog.bela.io/2016/11/15/analog-synth/

how does bela address LEDs / conversely, can we still program the BBB to directly address LEDstrips

SSL certificates expired on the Force so python script couldnt handshake with the force via webaudio but itll work

received bela - editor works on current setup downloaded fritzing and bela part how many outputs can it drive from a 5v power supply (max current draw)

learned the difference between sinf and sinf_neon (part of the math_neon)

figure out easiest way to send osc message from laptop on windows twisted: pipe network traffic from one port to another

figure out how to generate a square wave on one of the output pins (not the audio out!)

3/9/17

local fork of the force to investigate float/int communication to bela issue learning about floats v ints - FIXED

4/13/17

try analog out example w proper led parts rewrite analogoscout example after copy paste fiasco (Maybe:try using the scope monitoring to view inputs and outputs)

4/19

looks like problem was with chrome, save works fine in firefox made the analog out+osc properly compile, still blinks and receives message but doesn't print / process values properly... OSC routes fine from pd patches (uploaded those) tests fine with Rob sending osc packets over the local network

Todo:

• fix parsing and change rate of LED blinkage
• write the code to affect each channel independently
• test with synth
• figure out how to send data back from Bela
• design, source parts for and build circuit to interface / protect voltage ranges for I/O
• design interesting signals / shapes to make in PD to send to the synth
