Software

• Mainboard firmware: Marlin 2.0.9.2 (fork with config, see Marlin/Configuration{,_adv}.h)
  • diff: nvim -d {Marlin,config/Artillery/Genius}/Configuration.h, same for Configuration_adv.h
    • mostly calibration, new extruder and noise-free PWM for parts fan
    • LIN_ADVANCE instead of S_CURVE_ACCELERATION (don't work together)
  • before 13.11.2020: Marlin 2.0.5.3 (3dprintbeginner) (branch)
• TFT firmware: artillery_tft_fw_1.27.x_patch_9.2 (digant@thingiverse) (TFT-config.ini)
  • Put in Marlin mode (long press, persists on reboot) when printing with OctoPrint because TFT shares serial connection.

Guide to PROGMEM on ESP8266 and Arduino IDE

Intro

On low memory devices like the arduino and esp8266 you do not want strings to be stored in RAM. This occurs by default on these systems. Declare a string const char * xyz = "this is a string" and it will use up RAM.

The solution on these devices is to allow strings to be stored in read only memory, in Arduino this is the PROGMEM macro. Most of my experience is with the ESP8266 which is a 32bit micros controller. This device stores PROGMEM data in flash. The macro PROGMEM on ESP8266 is simply

#define PROGMEM   ICACHE_RODATA_ATTR

With the release of Vivaldi 2.2, this page is now obsolete and unmaintained. Widevine is fetched automatically on post install of our official packages. The information below and the script are left for historical reasons but will not be updated.

If you are using something newer than Vivaldi 2.2, you should not be using this script as there is simply no need. Any need you think you have for it would be a bug IMHO and thus should be logged in a bug report. Before you do so however, you should also checkout the Vivaldi help page on Widevine, on Linux
