Arduino V1.13.6

• Added ability to query homing status during Autohoming(:XGAH#)
• Fixed a bug in Autohomingthat would make it fail if it did not pass over the sensor during the initial 30 degree search
• Added debounce function to detection of sensor state changes in Autohoming. There were single false sensor trigger spikes that incorrectly detected sensor transitions.

• Switched back to official repo for SSD1306-based displays

Arduino V1.13.3

Since the last official release, which was V1.11.5, the following changes have been made:

V1.13.3 - Updates
NOTE: Make sure to do a Factory Reset when using this version.

• Allowed ALT steps per revolution to be set directly
• Removed drift alignment and added ability to add it back with define
• Optimized string memory a little
• Lowered ESP32 second core priority
• Added support for informational display (currently supports 128x64 OLED I2C displays)
• You must upgrade to OATControl V1.1.2.0 to use with this version (at least if you want to use the DEC park/unpark feature)

V1.13.2 - Updates

• Fix for RA steps being incorrectly set on every boot.

V1.13.1 - Updates

• Fix for uploading on AVR platform. Apparently [email protected] (current stable) is broken and can't upload, so we peg it at [email protected] for now.

V1.13.0 - Updates. This was a pre-release!

• Sped up ESP32 stepper code.
• Re-instate some defines that were inadvertently removed.
• Ported some bug fix code from the LCD branch (e.g. track on boot)
• Potentially some DEC guide issues were fixed.
• Inadvertently removed some default #defines. Put them back.
• Allow new stepper lib to be enabled by via #define
• Added ability to detect new firmware flashed
• Removed/disabled parking offset variable and commands, use home offset instead
• Fixed Park command to slew home and then to the parking position (home offset)
• Re-integrated old stepper library

V1.12.17 - Updates

• Fixed a bug that prevented clients from writing the DEC offset.

V1.12.16 - Updates

• Fixed a bug that prevented clients from reading the DEC offset.

V1.12.15 - Updates

• Corrected ALT calculation for OAM
• Allowed overriding AZ_CIRCUMFERENCE in local config
• Allowed overriding the maximum search distance for autohoming in local config, default remains 30degs

V1.12.14 - Updates

• Southern hemisphere fix
• Added and changed some logging

V1.12.13 - Updates

• Added ability to override RA Wheel circumference in local configuration
• Added a physical limit define which defines how far RA can turn before physical issues arise.
• Manual slewing now targets the physical limit of the axis, instead of just going x thousand steps.
• Added support to define the back slew distance that is required to un-signal a signaled end switch. Some
  mechanical switches have a hysteresis that requires a lot (600%!) of back movement to un-signal.
• Manual slewing termination was incorrect and not executing pending operations.
• Set Tracking compensation speed to slewing speed instead of other calculation that was way too slow and
  caused long post-slew delays.
• Firmware returns "OpenAstroMount" for :GVP# Meade command if compiled for OAM.
• Enhanced logging output to show time since last log output.

• Allowed the active state of the hall sensors for auto homing RA and DEC to be configured.

V1.12.10 - Updates

• Fixed a problem where slewing to targets more than 90degrees from the pole (in either hemisphere) would result in a target mirrored around the 'equator'.

V1.12.9 - Updates

• Fixed integer size mismatch for RA and DEC speeds. This caused integer overflows when RA was configured for 256 step microstepping.
• Added some logging at boot to show stepper variables.

V1.12.8 - Updates

• Fixed compile error caused by GPS being enabled in RAMPS environment.

V1.12.7 - Updates

• Fixed a bug where southern hemisphere setting would not persist between session.

V1.12.6 - Updates. This was a pre-release!

• Fixed all known issues related to running in the southern hemisphere.
• Added support for DIR inversion to interrupt stepper library.
• Hemisphere no longer needs to be defined in config, firmware determines it automatically from the given Latitude, switching at the equator.
• Fixed the logic in Sync call to account for both hemispheres.
• Fixed some logic that stopped tracking when setting home position.
• Fixed a bug that caused the firmware to fail to recognize the end of very short slews.
• Added Meade Extension command to query remaining tracking time
• Added Meade Extension command to query the hemisphere that is set.

  • Now using https://github.com/andre-stefanov/avr-interrupt-stepper instead of AccelStepper.
  • Now using dynamic interrupts instead of main loop for stepping control.
  • The maximum stepping rate (in total) increased drastically (theoretically up to 80.000 steps/s but it is recommended to stay under 40.000 to keep UART stable).
  • Improved stepping frequency stability and thus tracking speed accuracy.
  • ESP32 still uses AccelStepper (likely to change in future releases).
• Added CONFIG_VERSION validation to allow breaking changes in local configurations.

V1.11.15 - Updates

• Add DEC Autohoming via Hall sensor (same as RA Autohoming)

V1.11.14 - Updates

• Prevented firmware from hanging at boot if LCD is defined but not connected.
• Fixed a (rare) bug that would throw off GoTo commands when a target coordinate had been set.
