OSC operations for ESP8266 + Max7219 matrixs led with micropython. Need an ESP8266 on a local network with internet gateway at least for install.
|
|
|
|
OSC commands :
|
|
|
|
* /demo
|
|
* /cls
|
|
* /text 'sometext'
|
|
|
|
OSC port : 9001 (change OSCport in maxserver.py)
|
|
|
|
|
|
Obviously change /dev/cu.usbserial-1D1310 with your serial port like /dev/tty.USB0
|
|
|
|
Heavy use of https://github.com/mcauser/micropython-max7219 and https://github.com/SpotlightKid/micropython-osc
