Roxy-3D 3f0b38ed5d Add Max7219 LED Matrix Debug Support (#7563)
* Add Max7219 LED Matrix Debug Support

The Max7219 8x8 LED Matrix's are very helpful for debugging new code.
And for that matter, just trying to maximize printer settings without
causing stuttering.

The displays are very inexpensive (under $2.00 with shipping) and
provide a lot of help when trying to debug complicated code.

* Try to keep Makefile up to date.

Felix 2.0/3.0 Configuration for Marlin Firmware

Bringing silky smooth prints to Felix.

Build HOWTO

cd Marlin/Marlin
cp example_configurations/Felix/Configuration_adv.h .

The next step depends on your setup:

Single Extruder Configuration

cp example_configurations/Felix/Configuration.h .

Dual Extruder Configuration

cp example_configurations/Felix/DUAL/Configuration.h Configuration.h

Compile Firmware

  • Start the Arduino IDE.
  • Select Tools -> Board -> Arduino Mega 2560
  • Select the correct serial port in Tools -> Serial Port (usually /dev/ttyUSB0)
  • Open Marlin.pde or .ino
  • Click the Verify/Compile button

Flash Firmware

Connected directly via USB

  • Click the Upload button. If all goes well the firmware is uploading

Remote update

Find the latest Arduino build:

ls -altr /tmp/
drwxr-xr-x 5 chrono users 12288 Mar 3 21:41 build6072035599686630843.tmp

Copy the firmware to your printer host:

scp /tmp/build6072035599686630843.tmp/Marlin.cpp.hex a.b.c.d:/tmp/

Connect to your printer host via ssh, stop Octoprint or any other service that may block your USB device and make sure you have avrdude installed, then run:

avrdude -C/etc/avrdude.conf -v -v -v -patmega2560 -cwiring -P/dev/ttyUSB0 \
-b115200 -D -Uflash:w:/tmp/Marlin.cpp.hex:i
