for safety parsing OSC through i2c a logic level converter to use with Eurorack level (5V) is needed.

Quick Start

make sure you're already on Bela board (root@bela). and Bela's WIFI is setup, details here.

# download this repo to Bela.
git clone https://github.com/karnpapon/bela-i2c && cd bela-i2c

# run bela-osc
./build.sh

# build c++ file on Bela (more handy, if you don't want to open Bela user-interface and click build button.)
make -C ~/Bela PROJECT=render.cpp run CL="-p16"

# open another window
cargo run

Usage

osc pattern module/module_number/command/output_port value

msg	description	type	example
module	name of connecting module, currently support only ER301	String	er301
module_number	the order number of connecting module	Int	1
command	command to send to module available command for ER301 documentation please refer to this	String	cv_slew, tr_pulse, tr
output_port	output port number	Int	1
value	value to send to	Float	1000

please refer to module documentation use same configuration as Teletype (value = unsigned 14bits integer (16,384 = 10v))

[Example] sending data via WIFI (eg. use TouchOSC (Mobile) -> Bela)

• setup WIFI on Bela first, details here.
• make sure you're in same WIFI as Bela.
• on Bela
• get wlan IP by ip a on Bela board.
• on TouchOSC:
  • set HOST to IP obtained by previous command (eg. 192.168.1.115 as shown above).<
  • set Outgoing to 7562 (default Bela's listening port).
