Getting the Additional Libraries

There are several additional Arduino libraries that OnStep and its companion software might need depending on the Config.h options enabled.

Download and unzip the archive contents in your ~/Documents/Arduino/libraries folder to add support for any of these if needed.

• The Makuna DS3231 and DS3234 RTC Library - https://github.com/Makuna/Rtc/archive/master.zip
• The Arduiniana TinyGPS++ Library - http://arduiniana.org/libraries/tinygpsplus/
• The Adafruit Sensor Library (for the BMP280/BME280/etc.) - https://github.com/adafruit/Adafruit_Sensor/tree/ab724dd4d8d97a8e34a1da07914781be50aa1089
• The Adafruit BME280 Library - https://github.com/adafruit/Adafruit_BME280_Library/tree/156a0537d6b21aaab1d1f104a7001a38ca1ffce3
• The Adafruit BMP280 Library - https://github.com/adafruit/Adafruit_BMP280_Library
• The OneWire Library - https://github.com/hjd1964/OneWire
• The DS18B20 Library - https://github.com/hjd1964/Arduino-Temperature-Control-Library
• The Watterot DigitalWriteFast Library (for some STM32) - https://github.com/watterott/Arduino-Libs/archive/master.zip
• The u8g2 Library (SHC) - Arduino Library Manager, use version 2.32.15
• Tip:
  • This is not a complete list but these are the most commonly used libraries.
  • When compiling if a required library is not present, the compiler will throw an error and show the line of code where that error happened.  That line of code will always have a comment showing where to download the library.
  • Some libraries are available in the Arduino IDE for automatic download and install with the Sketch->Include Library->Manage Libraries... menu option.  Sometimes this can lead to trouble as specific library versions are in some cases required and/or not present.

• For the STM32F411 and STM32F401 BlackPill:
  • These have an ROM based DFU (default USB port) capable boot loader for firmware upload.
  • Board Generic STM32F4 series, Board part number BlackPill STM32F411 (or BlackPill STM32F401).
  • Upload method STM32CubeProgrammer (DFU).
  • U(S)ART Support Enabled (no generic 'Serial').
  • USB Support CDC (generic 'serial' superseded U(S)ART).
  • Press and hold button BOOT0 while powering on or resetting then release BOOT0.
  • On Linux, if you installed the stm32flash program, then use the command: stm32flash -g 0x8000000 -b 115200 -w /path/to/OnStep.ino.bin /dev/ttyUSB0
